During a comprehensive System Study in systems analysis, what activities are included: studying the existing system, documenting it thoroughly, and identifying current deficiencies to set new goals?

Introduction / Context:
A System Study is the opening chapter of any structured systems development life cycle. Its purpose is to understand the as-is environment, capture facts, and translate gaps into measurable goals for the to-be solution. Success here reduces rework and cost later.

Given Data / Assumptions:

• The organization has an existing process or application in production.
• Stakeholders want improvements aligned with business objectives.
• The question asks which activities belong to the System Study phase.

Concept / Approach:
System Study (also called preliminary investigation) typically has three pillars: discovery (study the current system), documentation (record workflows, data, controls, and volumes), and diagnosis (identify deficiencies and set objectives/constraints). These feed feasibility analysis and later detailed design.

Step-by-Step Solution:

Verification / Alternative check:
Well-known SDLC frameworks describe initial phases that culminate in a problem statement, objectives, scope, and baseline documentation—matching the three listed activities.

Why Other Options Are Wrong:

• Study alone misses formal capture and goal setting.
• Documentation alone lacks context and improvement targets.
• Deficiency identification alone lacks grounding in real operations.
• Thus the complete and correct choice is 'All of the above'.

Common Pitfalls:
Jumping to solutions without documenting facts, ignoring controls/compliance, and failing to quantify problems (e.g., cycle time, error rates, costs).

Final Answer:
All of the above
