Modern Cost Estimation Approaches

Modern software projects often use Agile methods to estimate costs. These methods are flexible and adapt to changes. Two popular techniques are Planning Poker and T-shirt sizing.

Planning Poker

Planning Poker is a team-based estimation game. Each team member gets cards with numbers. These numbers represent effort or complexity. Team members pick a card to estimate a task. Everyone shows their card at the same time. The team discusses any big differences in estimates. This helps the team agree on how much work a task needs.

T-shirt Sizing

T-shirt sizing assigns sizes like Small, Medium, or Large to tasks. Each size matches the amount of effort a task requires. This method is quick and easy to understand. It helps teams estimate without getting stuck in details.

Cost Estimation Models

There are models that help estimate software development costs. Three common ones are COCOMO, Function Point Analysis, and Use Case Points.

COCOMO

COCOMO stands for Constructive Cost Model. It uses math formulas to predict costs. The model looks at factors like size and complexity. It also considers the team's experience. COCOMO helps estimate how much time and effort a project will need.

Function Point Analysis

Function Point Analysis measures the functions of the software. It counts things like inputs and outputs. It also looks at user interactions. This method helps estimate effort based on what the software does.

Use Case Points

Use Case Points estimate effort based on use cases. A use case describes how a user interacts with the system. This method counts the number of use cases. It adjusts for how complex each one is. This helps predict how much work the project will involve.
