Key Insights

• 🫥 Size-based estimation can be done using lines of code (LOC) or function points (FP).
• 💁 Problem-based estimation focuses on determining size using information domain variables.
• 🍳 Process-based estimation involves breaking down the software into tasks and estimating effort for each task.
• 👪 The Kokomo family includes different models for different stages of the software development life cycle.
• ⚾ Empirical parametric methods, like Kokomo, provide formulas based on experimentally determined variables.

Questions & Answers

Q: What are the steps for LOC-based estimation?

The steps for LOC-based estimation include determining the size in terms of lines of code, estimating the cost and effort, and using statistical methods to find the mean value.

Q: How are function points used for problem-based estimation?

Function points are used to determine the size of a software project based on the information domain variables, such as external input, external output, and internal logical file. The size is then used to estimate effort and cost.

Q: How is process-based estimation different from other methods?

Process-based estimation focuses on breaking down the software into small tasks and estimating effort for each task. It uses a work breakdown structure and considers both engineering and project management tasks.

Q: What are the different models in the Kokomo family of estimation methods?

The Kokomo family includes basic Kokomo (Kokomo 81), intermediate Kokomo, complete Kokomo, Kokomo II, and CocoMOM. Each model is designed for specific types of software projects and offers different formulae for estimation.
