Software Engineering: Project Estimation

Project Estimation Objectives

• Estimation of projects involves assessing multiple factors including team size, time, and costs.
• Teamwork estimation focuses on predicting how many team members are required.
• Time estimation aims to determine the total duration for project development.
• Cost estimation calculates the overall financial requirements for the project.

Projects Estimations Process

• An important activity in software definition is project estimation.
• Estimates help identify the size of the development team needed.
• It determines the total time allocated for the development process.
• It calculates the total cost for completing the project.

Employment Rate and its Importance

• Estimating the employment rate of the development team is crucial for projecting actual costs.
• Higher employment rates typically indicate longer project timeframes, especially during the detailed design stage.

Total System Time Estimation

• Total system time is estimated by dividing the project's size by the individual effort expected in a month.
• This calculation helps in planning and distributing project timelines effectively.

Distribution of Project Time

• An agreed-upon distribution allocates project time across different phases, such as:
  • 2% of total time for requirements analysis.
  • Remaining time divided among design, programming, and production phases.

Factors Contributing to System Setup Failures

• Requirements edits can lead to misalignment and failures in project setup.
• Reliance on previous studies must be approached cautiously to avoid literal implementation without context.

Project Cost Estimation Techniques

• Essential methods for cost estimation include:

  • Top-Down Method: Calculates total project costs based on visual and invisible factors, such as:
    • Preparing team costs.
    • Accounting for costs of operational resources.
    • Training system users.

• Bottom-Up Method: Focuses on estimating costs of individual system components (subsystems) but excludes administrative work costs.
