Single Correct Answer Multiple Choice Question

A type of exam question that presents a statement with multiple choices, only one of which is correct. The correct answer is often disguised by plausible incorrect options.

Multiple Correct Answer Multiple Choice Question

A type of exam question that presents a statement with multiple choices, and more than one choice may be correct. The learner must identify all the correct answers.

Critical Path Analysis

A technique used to identify the critical path in a project, which is the sequence of activities that determines the shortest possible completion time for the project.

PERT Analysis (Program Evaluation and Review Technique)

A method for estimating the duration of a project by considering the optimistic, pessimistic, and most likely durations of each activity.

Time Estimate Accuracy

Critical path analysis relies on accurate time estimates for each task. If these estimates are inaccurate, the analysis might be misleading.

Ignoring Non-Critical Tasks

Critical path analysis focuses on the longest path in a project, potentially neglecting tasks outside the critical path that could impact the project's timeline if delayed.

Flexibility in Project Execution

Critical path analysis assumes a fixed sequence of tasks and durations. In reality, projects can be dynamic, with changes in task order or durations.

Benefits of Critical Path Analysis

The benefit of using critical path analysis is that it allows for the identification of the most important tasks in a project. This allows for a focused effort on these tasks and allows better control of the project schedule.

Oversimplification in Critical Path Analysis

A common problem in critical path analysis is that it can be overly simplified and may not account for all possible factors that could affect the project's schedule.

Study Notes

CS3SPM Assessment Material

  • The exam format differs from previous years.
  • Section A (compulsory) is now 20 marks of multiple choice, rather than 35 marks written.
  • Section B has three 40-mark questions, students can answer two.
  • The exam is 100 marks and 2 hours long.

Multiple Choice Questions

  • Expect single-correct-answer and multiple-correct-answer questions.
  • Example of a multiple-correct-answer question: nominal data examples.

Agile Development Characteristics

  • Agile development characteristics:
    • Work is organized into sprints.
    • Each phase is thoroughly documented.
    • Change is viewed positively.
    • Teams of any size can work in an agile way.

Nominal Data Example

  • Examples of nominal data:
    • Number of people on a team
    • Language used on a project
    • Defects/SLOC
    • Project duration as a percentage of another project's duration
    • Phase of the current project

Critical Path Analysis Example

  • A table shows tasks, prerequisites, and durations for a project.
  • Instructions to create a network diagram, calculate project duration, and define critical path.
  • Instructions identifying delays in tasks, impacting the critical path.
  • Question on the limitations of critical path analysis.

Formulae for the Exam
