Question 1

Activities vs. events – identify the incorrect statement Which of the following statements about project activities and events is wrong?

Accepted Answer

Introduction / Context: Project networks distinguish between activities (work that takes time/resources) and events (milestones or instantaneous points). Confusing the two leads to faulty schedules and misleading progress tracking. Given Data / Assumptions: Activity: time- and resource-consuming task (e.g., “turn job on lathe”). Event: a zero-duration milestone (e.g., “job turned”). We follow standard CPM/PERT terminology. Concept / Approach: An activity is the process; an event is the state change marking its start or completion. Activities are represented by arrows or bars; events by nodes or milestones with zero duration. Step-by-Step Solution: Identify which statement reverses definitions.“Turning of a job on a lathe” clearly consumes time/resources, so it is an activity.“Job turned” signifies completion, which is an event (instantaneous).Therefore, the given statement in option (d) is wrong. Verification / Alternative check: Gantt or arrow diagrams label activities with durations; milestones have zero duration and mark “start” or “finish” events like “job turned.” Why Other Options Are Wrong: Options (a), (b), and (c) correctly reflect standard definitions; option (e) cannot be true because one statement is indeed wrong. Common Pitfalls: Treating milestones as buffer tasks; assigning resources to events. Final Answer: The turning of a job on a lathe is an event, whereas “job turned” is an activity.

Question 2

Methods-Time Measurement (MTM): What is MTM primarily used for in industrial engineering and work study?

Accepted Answer

Introduction / Context: Methods-Time Measurement (MTM) is a classic predetermined motion time system used in industrial engineering and work study. It decomposes manual tasks into basic motions and assigns standard times to each motion, allowing analysts to design or evaluate methods before the job reaches the shop floor. Given Data / Assumptions: An MTM system is available (e.g., MTM-1, MTM-2) with a recognized set of motion codes and times. Objective: clarify the primary uses of MTM in a production context. Focus on method improvement, time setting, and pre-production method design. Concept / Approach: MTM converts observed or planned motions into standard times independent of individual worker pace. Because of this, MTM supports three major aims: designing efficient methods in advance, improving existing methods by eliminating waste motions, and establishing fair, defendable time standards without prolonged stop-watch studies. Step-by-Step Solution: Identify MTM as a predetermined time system based on basic human motions.Use MTM tables to calculate operation time from motion sequences.Apply the analysis to compare alternatives and remove non-value-adding elements.Adopt the final motion sequence as the standard method and its computed time as the standard time. Verification / Alternative check: Cross-check MTM-derived standards with pilot runs or limited time studies; results typically align closely, validating that MTM can substitute or complement traditional timing. Why Other Options Are Wrong: Each individual purpose listed (only improvement, only time standards, only pre-production method design) captures part of MTM, but MTM is commonly used for all of them together. Common Pitfalls: Confusing MTM with simple stop-watch timing; ignoring allowances for fatigue and delays; assuming MTM is only for repetitive work—while best for repetition, it can inform low-variation tasks too. Final Answer: All of the above

Question 3

Facility layout and scheduling: In which layout is production scheduling simpler, enabling high output and high labour efficiency?

Accepted Answer

Introduction / Context: Facility layout decisions impact throughput, scheduling, material handling, and labour productivity. A product (line) layout arranges resources in the sequence of operations for one or a few high-volume products, whereas process layouts group similar machines, and fixed position layouts keep the product stationary. Given Data / Assumptions: The goal is to simplify scheduling and achieve high output with high labour efficiency. Products are standardized or have limited variants. Demand is steady enough to balance the line. Concept / Approach: In a product layout, each workstation performs a fixed, repetitive task; jobs flow in a single, predefined path. Line balancing and takt-based planning simplify scheduling. Workers specialize, changeovers are minimized, and material flow is streamlined, raising output and labour efficiency compared with process or fixed-position layouts. Step-by-Step Solution: Identify the need for simple scheduling and high volume.Map this need to a stable sequence of operations suited to a line.Recognize that product layout minimizes routing complexity and WIP.Conclude that product (line) layout best satisfies the criteria. Verification / Alternative check: Empirical results in assembly lines (e.g., consumer goods, automotive subassemblies) show predictable schedules and high throughput when demand is stable. Why Other Options Are Wrong: Process layout: flexible but complex routing and scheduling; higher WIP. Fixed position layout: suited for large projects; scheduling is component/crew oriented and complex. Combination layout: useful when needed, but typically more complex to schedule than a pure line. Common Pitfalls: Trying to use a line layout for highly customized products; ignoring balance losses and bottlenecks that reduce theoretical efficiency. Final Answer: Product (line) layout

Question 4

Quality control strategy: Acceptance sampling is most appropriately applied in which production context?

Accepted Answer

Introduction / Context: Acceptance sampling is a statistical quality control technique for deciding whether to accept or reject a lot (batch) based on inspecting a sample rather than 100% of items. It balances inspection costs with risks of accepting bad lots or rejecting good ones. Given Data / Assumptions: A “lot” or “batch” exists that groups many similar units. Sampling plans (e.g., single, double, or sequential) are available. Inspection is destructive or costly enough to avoid 100% inspection. Concept / Approach: Acceptance sampling requires a population of items produced under similar conditions, naturally aligning with batch production where lots are formed. While mass production also forms lots, the question asks for the most appropriate context from the listed choices with one correct answer; batch production is the canonical fit because the term “lot” literally corresponds to batches dispatched or received. Step-by-Step Solution: Identify that acceptance sampling evaluates a lot based on a sample.Recognize that lots are inherent in batch production.Infer that job production (one-off) has no meaningful lot to sample.Select “Batch production” as the best match. Verification / Alternative check: Standard texts define acceptance sampling in the context of lot-by-lot inspection, frequently illustrated with batch receipts from suppliers. Why Other Options Are Wrong: Job production: no lot to sample; full inspection or bespoke assurance is typical. Mass production: possible, but many systems move to process control; the question expects the prototypical “batch” context. All of these: incorrect because job production does not suit lot sampling. Common Pitfalls: Confusing acceptance sampling with statistical process control (SPC); SPC monitors process over time, while acceptance sampling decides lot disposition. Final Answer: Batch production

Question 5

Break-even analysis: The break-even point on a cost–volume–profit (CVP) chart is the intersection of which two lines?

Accepted Answer

Introduction / Context: Break-even analysis studies how costs and revenues change with volume to determine the output level at which a business neither makes a profit nor a loss. The break-even point (BEP) is a cornerstone of managerial decision-making. Given Data / Assumptions: Total cost = Fixed cost + Variable cost. Sales revenue = Selling price per unit * Quantity. Linear relationships are assumed over the relevant range. Concept / Approach: On a CVP graph, the total cost line starts at the fixed cost on the Y-axis and rises with slope equal to unit variable cost. The sales revenue line passes through the origin with slope equal to selling price per unit. The BEP occurs where total cost equals total revenue, i.e., profit = 0. Step-by-Step Solution: Plot fixed cost as a horizontal line; total cost adds the variable component.Plot the revenue line through the origin with slope equal to price.Find the intersection of total cost and sales revenue lines.That intersection gives BEP units and BEP revenue. Verification / Alternative check: Algebraically, BEP quantity Q = Fixed cost / (Price per unit - Variable cost per unit). At this Q, total cost equals total revenue, matching the graph intersection. Why Other Options Are Wrong: Fixed vs variable cost lines: their intersection is not BEP. Fixed vs total cost lines: they intersect at the fixed-cost intercept only. Variable vs total cost lines: always parallel difference by fixed cost; no BEP meaning. Common Pitfalls: Using average cost instead of marginal; forgetting the relevant range where linearity holds. Final Answer: Sales revenue and total cost lines

Question 6

Components of break-even analysis: Which elements are included in a standard cost–volume–profit study?

Accepted Answer

Introduction / Context: Break-even (CVP) analysis quantifies how profits respond to changes in volume by modeling revenue and costs. Understanding the inputs ensures accurate computation of BEP and margin of safety. Given Data / Assumptions: Fixed expenses do not vary with volume within the relevant range. Variable cost changes directly with units produced/sold. Sales revenue is price per unit times quantity. Concept / Approach: Profit = Sales revenue - Total cost, and Total cost = Fixed expenses + Variable cost. CVP analysis requires all three components to derive BEP, contribution margin, and profit targets. Step-by-Step Solution: Express total cost as fixed + variable.Compute contribution margin per unit = Price - Variable cost per unit.Calculate BEP units = Fixed expenses / Contribution margin per unit.Relate profit targets to the same three components. Verification / Alternative check: Graphical CVP shows fixed cost, total cost, and revenue lines; the intersection defines BEP, confirming the role of all three. Why Other Options Are Wrong: Picking any single element ignores the integrated nature of CVP; you need all components to compute BEP. Common Pitfalls: Forgetting to separate semi-variable costs into fixed and variable parts; using list price instead of realized net price. Final Answer: All of these

Question 7

Inventory control – EOQ: In the classical Economic Order Quantity model, EOQ occurs where ordering cost equals carrying (holding) cost. Is this statement true?

Accepted Answer

Introduction / Context: The Economic Order Quantity (EOQ) model determines the order size that minimizes total annual inventory cost by balancing ordering costs against carrying (holding) costs for steady demand. Given Data / Assumptions: Deterministic, constant annual demand D. Ordering cost per order S and annual holding cost per unit H. No shortages; instantaneous replenishment; constant prices. Concept / Approach: Total annual cost = Ordering cost + Holding cost = (D/Q)S + (Q/2)H. Differentiating with respect to Q and setting derivative to zero yields the optimal Q and implies equality of ordering and holding costs at the optimum. Step-by-Step Solution: Total cost TC(Q) = (D/Q)S + (Q/2)H.Set dTC/dQ = -DS/Q^2 + H/2 = 0.Solve for Q = sqrt(2DS/H).At Q, Ordering cost = (D/Q)S and Holding cost = (Q/2)H are equal. Verification / Alternative check: Substitute Q into both cost components to confirm equality; both evaluate to sqrt(DSH/2), proving the balancing condition. Why Other Options Are Wrong: “False” contradicts the first-order optimality condition in the basic EOQ model. Common Pitfalls: Applying the equality when quantity discounts, shortages, or variable demand invalidate the classical assumptions; in those cases, the condition may not hold. Final Answer: True

Question 8

Organisation structure: Line organisation is most suitable for which types of industries?

Accepted Answer

Introduction / Context: Organisation design affects authority, communication, and control. Line organisation features a clear, direct chain of command from top to bottom, best for stable, routine operations with standardized processes. Given Data / Assumptions: Industries listed perform repetitive, process-oriented operations. Decision-making can be centralized with clear authority lines. Low product variety and stable processes. Concept / Approach: Where tasks are routine and interdependencies are sequential, line structures can deliver clarity, speed of decisions, and accountability. Industries like sugar, oil refining, and textiles often exhibit continuous or repetitive processes suited to line or line-and-staff forms; the core line chain remains dominant for operations control. Step-by-Step Solution: Identify industry characteristics: repetitive, standardized, and process-driven.Map these to the strengths of line organisation: simplicity and unity of command.Conclude that all listed industries can adopt line-dominant structures effectively.Choose “All of these”. Verification / Alternative check: Organisational case studies show line or line-and-staff prevalence in continuous processing plants due to clear process flow and safety-critical command chains. Why Other Options Are Wrong: Choosing only one industry ignores the general applicability of line structures across similar process industries. Common Pitfalls: Confusing pure line with line-and-staff; many large plants add staff functions, but the line authority remains primary. Final Answer: All of these

Question 9

Operations research application: Queuing theory is applied to which of the following problem domains?

Accepted Answer

Introduction / Context: Queuing theory studies waiting lines where entities arrive, wait for service, are served, and depart. It is an operations research tool for designing and controlling service systems, manufacturing flows, and transportation networks. Given Data / Assumptions: Stochastic arrivals (often Poisson) and service times (e.g., exponential) are common assumptions. Performance measures include average queue length, waiting time, server utilization, and probability of delay. Goal is to balance service capacity against waiting costs. Concept / Approach: Queuing models (e.g., M/M/1, M/M/c, M/G/1) capture the dynamics of systems with variability. They apply to machine repair, call centers, hospital triage, traffic intersections, and even production scheduling when stations and buffers behave as queues. Step-by-Step Solution: Formulate arrival and service processes and choose an appropriate queue model.Compute key metrics (utilization rho, Lq, Wq, L, W) to evaluate system performance.Use results to size servers, set priorities, or sequence jobs to reduce waiting and congestion.Generalize insights to traffic and inventory-related service contexts where replenishment or checkout behaves as a queue. Verification / Alternative check: Simulation of arrival/service variability confirms analytical predictions and aids complex, non-Markovian cases. Why Other Options Are Wrong: Each single domain alone underrepresents the breadth of queuing theory; it is relevant across all listed areas. Common Pitfalls: Assuming deterministic flow; neglecting variability leads to undersized capacity and long waits. Final Answer: All of these

Question 10

Project management acronyms: In network planning, CPM stands for which term?

Accepted Answer

Introduction / Context: CPM is a fundamental technique in project management for planning, scheduling, and controlling complex projects by identifying the longest path of dependent activities that determines the minimum project duration. Given Data / Assumptions: Activities with specified durations and precedence relationships. No resource leveling in the basic algorithm. Deterministic activity times in classic CPM (PERT uses probabilistic times). Concept / Approach: Critical Path Method computes earliest and latest start/finish times, floats, and identifies the critical path with zero total float. Managing critical activities prevents schedule slippage. Step-by-Step Solution: Construct the activity-on-node network with dependencies.Perform forward pass to get earliest start/finish times.Perform backward pass to get latest start/finish times.Identify activities with zero float; their chain is the critical path. Verification / Alternative check: Compare computed project duration with simulation or historical benchmarks; changes in any critical activity immediately change total duration. Why Other Options Are Wrong: Alternative expansions are nonstandard; CPM universally abbreviates Critical Path Method. Common Pitfalls: Ignoring resource constraints and assuming durations are fixed; in practice, resource leveling may alter the critical path. Final Answer: Critical Path Method

Question 11

Operations research – optimization: The mathematical technique for best allocation of limited resources to maximize or minimize an objective is called

Accepted Answer

Introduction / Context: When resources such as materials, labour hours, machine time, or budget are limited, managers seek an optimal allocation that maximizes profit or minimizes cost. Linear programming (LP) is the core operations research method for such problems with linear objectives and constraints. Given Data / Assumptions: An objective function that is linear in decision variables (e.g., maximize profit = c1x1 + c2x2). Linear constraints representing resource limits (e.g., a11x1 + a12x2 ≤ b1). Non-negativity of decision variables. Concept / Approach: LP models define a feasible region (a convex polytope). The optimal solution lies at an extreme point of this region. Algorithms such as the simplex method or interior-point methods efficiently find the optimum in large problems. Step-by-Step Solution: Formulate decision variables representing production or allocation choices.Write the linear objective to maximize or minimize.Translate resource limits into linear inequalities or equations.Solve using simplex or an LP solver to get optimal variable values and shadow prices. Verification / Alternative check: Sensitivity analysis tests robustness of the solution to changes in coefficients, validating practical implementability. Why Other Options Are Wrong: Value analysis: improves product value by function–cost study, not optimization modeling. Network analysis: schedules projects (CPM/PERT), not general resource allocation. Queuing theory: analyzes waiting lines rather than solving linear allocation problems. Common Pitfalls: Modeling nonlinear realities as linear without justification; forgetting integer requirements that would require integer programming. Final Answer: Linear programming

Question 12

In production planning and control, what does “scheduling” primarily specify? (Assume a typical manufacturing shop with defined routing and dispatching functions.)

Accepted Answer

Introduction / Context: Within production planning and control, different functions have precise meanings. Confusing routing, scheduling, dispatching, and follow-up leads to poor coordination. This question checks whether you can identify the core role of scheduling. Given Data / Assumptions: A manufacturing setting with known process routes for parts. Standard definitions of routing, scheduling, dispatching, and follow-up. Objective is timely completion with balanced machine loading. Concept / Approach: Scheduling creates the time-table. It fixes when each operation should start and finish on specific resources, subject to capacity constraints and due dates. Routing defines where work should go; dispatching releases work-orders; follow-up (or expediting) monitors actual progress against plan. Step-by-Step Solution: Clarify terms: routing = path; scheduling = timing; dispatching = authorising start; follow-up = control of progress.Match the option that describes timing of operations.Option (b) states the detailed programme (start/finish) → scheduling. Verification / Alternative check: Textbook PPC frameworks always depict scheduling as the time dimension, complementing routing (sequence) and dispatching (release). Why Other Options Are Wrong: (a) Routing concerns the route/sequence, not the calendar.(c) Dispatching triggers starts but does not plan times in detail.(d) Follow-up regulates progress and handles delays.(e) Time study sets standard times, not shop calendars. Common Pitfalls: Equating “sequence” with “schedule”; assuming dispatching is the same as scheduling. Final Answer: Determines the detailed programme of start and finish times for operations (time-table of work)

Question 13

Industrial engineering: What does a comprehensive time study typically involve before establishing a reliable standard time?

Accepted Answer

Introduction / Context: Time study is a cornerstone of work measurement. It establishes a fair and achievable standard time by observing work, analysing elements, and applying ratings and allowances. A narrow approach risks inaccurate standards. Given Data / Assumptions: A defined repetitive operation suitable for stop-watch study. Competent, trained operator under normal working conditions. Use of standard rating and allowance practices. Concept / Approach: A robust time study includes: gathering contextual information (method, tools, layout), element breakdown for clarity, direct timing of several cycles, performance rating to convert observed to normal time, and allowances to cover fatigue, personal needs, and delays. Step-by-Step Solution: Record job details, conditions, and method to ensure reproducibility.Break the job into small, definable elements to improve consistency.Time multiple cycles, compute representative (average) time, apply rating to get normal time, then add allowances to obtain standard time. Verification / Alternative check: Standard IE texts (work measurement) prescribe exactly these steps; omitting any reduces validity. Why Other Options Are Wrong: Options (a), (b), and (c) alone are incomplete; the correct practice is all combined.“Only rating” without observation is impossible and invalid. Common Pitfalls: Not stabilising the method before study; too few cycles; ignoring allowances; poor element definition. Final Answer: All of the above

Question 14

Organisational design: In a classic functional organisation (specialist departments), which of the following advantages typically apply?

Accepted Answer

Introduction / Context: Functional organisation groups activities by specialism (e.g., planning, quality, maintenance). Expertise deepens, but coordination requires care. This question focuses on typical advantages. Given Data / Assumptions: Functional lines staffed by specialists. Clear allocation of technical responsibilities. Stable, routine manufacturing environment. Concept / Approach: Specialisation enhances know-how, standardisation, and process control. This often improves quality, reduces waste, and provides continuous expert guidance and training to operators. Step-by-Step Solution: Identify benefits linked to specialisation: depth of expertise → quality improvement.Expert oversight and standard methods → lower wastage.Departmental experts → better guidance to workers. Verification / Alternative check: Management literature cites better technical control and economies of specialisation as advantages, despite drawbacks like weaker unity of command. Why Other Options Are Wrong: Single benefits alone understate the broader advantages of functional organisation.“Only faster communication” is not a typical primary advantage; communication can, in fact, be slower across functions. Common Pitfalls: Ignoring disadvantages (conflicting authority, coordination overhead) while acknowledging valid strengths. Final Answer: All of the above

Question 15

Value analysis (cost reduction for existing products) is especially worthwhile under which production context?

Accepted Answer

Introduction / Context: Value analysis reviews an existing design to maintain function while lowering cost. Its payoff depends on how often the savings recur, making production scale a key driver. Given Data / Assumptions: Existing product with established function and performance. Feasible alternatives in materials, processes, or tolerances. Implementation costs can be amortised over production volume. Concept / Approach: Because value analysis generates repeated per-unit savings, it is most attractive where unit volumes are high. Even small cost reductions yield large total savings when multiplied by thousands or millions of units. Step-by-Step Solution: Assess production context: jobbing vs. mass.Recognise that fixed effort of analysis is justified by recurring savings.Select large-scale production as the best scenario. Verification / Alternative check: Case studies from automotive and appliances consistently show large returns from value analysis because of high volumes. Why Other Options Are Wrong: Jobbing/small runs: savings do not recur enough to offset effort.Few components or prototypes: benefits are limited by low repetition.Costly equipment alone does not guarantee payoff without volume. Common Pitfalls: Ignoring tooling and qualification costs; overlooking life-cycle impacts (warranty/quality) when making substitutions. Final Answer: Large-scale or mass production where savings repeat across many units

Question 16

Work measurement: “Standard time” for an operation is defined as which of the following?

Accepted Answer

Introduction / Context: Accurate standards underpin planning, costing, and incentive schemes. The relationship among observed time, normal time, and standard time must be clear to avoid under- or over-estimating capacity. Given Data / Assumptions: Observed times taken over several cycles. Performance rating system to convert to normal time. Allowances for fatigue, personal needs, and delays. Concept / Approach: Representative (average) observed time * rating factor = normal time. Then, standard time = normal time + allowances. This ensures the standard reflects both expected performance and legitimate interruptions. Step-by-Step Solution: Compute average observed time.Apply rating: normal time = representative time * rating factor.Add allowances: standard time = normal time + allowances. Verification / Alternative check: Classic work measurement texts define standard time exactly as normal time plus allowances. Why Other Options Are Wrong: (a) Subtracting allowances is incorrect.(c) Describes normal time, not standard time.(d) A single fastest cycle is not representative.(e) Allowances alone are meaningless without normal time. Common Pitfalls: Using too few observations; misrating performance; misapplying allowances. Final Answer: Normal time plus allowances

Question 17

In time study terminology, the average time recorded across observed cycles (before applying performance rating) is called the ________.

Accepted Answer

Introduction / Context: Understanding the ladder from observed time to standard time is essential: observed → representative → normal → standard. Each step formalises adjustments for performance and allowances. Given Data / Assumptions: Multiple cycle observations are timed. Performance rating and allowance systems are available. Stable method and conditions. Concept / Approach: Representative time is the mean (or statistically suitable average) of observed times after eliminating abnormal values. Normal time = representative time * rating factor. Standard time = normal time + allowances. Step-by-Step Solution: Collect observed times → compute average → representative time.Apply rating → obtain normal time.Add allowances → obtain standard time. Verification / Alternative check: Time study manuals explicitly define these terms in the same sequence. Why Other Options Are Wrong: Standard/Normal are later-stage results; allowance time is only a component.“Rated time” is ambiguous and not the standard terminology here. Common Pitfalls: Confusing “normal” with “observed”; failing to filter outliers before averaging. Final Answer: Representative (average observed) time

Question 18

Production control visuals: A Gantt chart (bar chart) is primarily used to communicate which of the following on a time scale?

Accepted Answer

Introduction / Context: Gantt (bar) charts are classic tools to show planned and actual timing of activities. They provide a visual schedule that managers and operators can understand at a glance. Given Data / Assumptions: Activities or jobs with start and finish dates/times. A need to track progress versus plan. Possibly multiple machines or departments. Concept / Approach: A Gantt chart represents activities as bars on a time axis. It communicates when jobs should start/finish and how they overlap, and it can display progress. Routing is a different document; detailed machine utilisation typically requires load charts or analytics. Step-by-Step Solution: Identify the primary communication need: schedule on a timeline.Map each job/operation as a bar with planned duration.Optionally overlay actual progress for control. Verification / Alternative check: Standard PPC references list Gantt charts for scheduling and progress tracking, not for routings or sales metrics. Why Other Options Are Wrong: Routing sheets show sequences and work centers, not time bars.Sales and inventory topics are unrelated to Gantt timing bars.Machine utilisation can be inferred but is not the primary purpose. Common Pitfalls: Overloading the chart; failing to update progress; ignoring resource conflicts not evident on a simple bar chart. Final Answer: Production schedule and progress of jobs/operations over time

Question 19

Principles of material handling: Which set best reflects widely accepted handling principles?

Accepted Answer

Introduction / Context: Material handling strongly affects cost, safety, and throughput. Foundational principles emphasise eliminating unnecessary moves, choosing proper equipment, and minimising distances and touches. Given Data / Assumptions: General factory layout with multiple handling alternatives. Varied loads (weights, volumes) and paths. Goal is lower cost per unit with improved flow. Concept / Approach: Classical principles include: plan handling; use gravity and shortest paths; minimise handling; standardise methods; select efficient equipment; and match the system to load characteristics and flow requirements. Step-by-Step Solution: Eliminate non-value handling → reduce cost and risk.Choose equipment that fits load, distance, and frequency to raise efficiency.Short, direct routes and minimal moves for heavy loads reduce effort and time. Verification / Alternative check: IE references list nearly identical principles under various wordings, all aligning with options (a), (b), and (c). Why Other Options Are Wrong: (e) Automation is a tool, not a principle; poor methods automated become expensive mistakes. Common Pitfalls: Automating bad layouts; ignoring ergonomics; underutilising gravity or unit loads. Final Answer: All of the above

Question 20

Value engineering job plan: Choose the correct sequence of the early phases (using the closest standard terminology available in the options).

Accepted Answer

Introduction / Context: Value engineering follows a structured job plan to improve value (function/cost) for a product or process. Understanding the phased sequence ensures disciplined creativity and sound decisions. Given Data / Assumptions: Standard VE approach with cross-functional team. Phases include information, creative (idea generation), analysis/investigation, and evaluation/selection. Later phases such as development and presentation follow, but are outside this question. Concept / Approach: The usual early sequence is: gather facts (information), generate alternatives (creative/speculation), analyse functions/costs and feasibility (investigation/analysis), and then evaluate/select the best ideas (evaluation) for development. Step-by-Step Solution: Start with Information: define functions, costs, constraints.Creative: brainstorm ideas freely without judging.Investigation/analysis: screen and analyse ideas for merit and feasibility.Evaluation: rank and select concepts to carry forward. Verification / Alternative check: Classical VE texts describe the same flow; naming varies, but the sequence of information → creativity → analysis → evaluation is consistent. Why Other Options Are Wrong: Options starting with Creative skip the essential fact-finding foundation.Sequences that jumble phases break the logic of ideation followed by analysis and selection. Common Pitfalls: Prematurely evaluating ideas (stifles creativity); weak information phase leading to solving the wrong problem. Final Answer: Information phase → Creative (speculation) phase → Investigation/analysis phase → Evaluation phase
