How to fill out measuring cohesion and coupling

1. Understand the concept of cohesion and coupling: Cohesion refers to how closely the components of a module or class are related to each other and how much they work together as a coherent unit. Coupling refers to the interdependence between different modules or classes in a system.
2. Determine the purpose of measuring cohesion and coupling: Measuring cohesion and coupling can help evaluate the design and architecture of a software system. It can aid in identifying potential issues related to modularization, dependencies, and maintainability.
3. Identify the metrics for measuring cohesion and coupling: There are several metrics available to measure cohesion and coupling, such as LCOM (Lack of Cohesion in Methods), CBO (Coupling Between Objects), and RFC (Response For a Class). Each metric focuses on different aspects of cohesion and coupling.
4. Define the criteria and thresholds for measuring cohesion and coupling: Based on the specific context and requirements of the system, establish the desired level of cohesion and coupling. This can be done by setting thresholds or guidelines for each metric that should be met.
5. Collect data and calculate the metrics: Analyze the software system's codebase and collect relevant data for the chosen metrics. Use appropriate tools or techniques to calculate the cohesion and coupling metrics based on the collected data.
6. Interpret the results and take action: Once the metrics are calculated, interpret the results to evaluate the cohesion and coupling of the system. Identify any areas that need improvement or optimization. Take appropriate actions to address the issues and improve the overall design and architecture of the system.

Who needs measuring cohesion and coupling?

1. Software architects and designers: Measuring cohesion and coupling can assist architects and designers in assessing the quality of a software system's design and making informed decisions about architectural improvements.
2. Software developers: Developers can benefit from measuring cohesion and coupling to identify areas of the codebase that are highly coupled or have low cohesion. This information can help them refactor the code for better maintainability and modularization.
3. Project managers: Project managers can utilize cohesion and coupling measurements to identify potential risks and dependencies in the software system. This information can aid in resource allocation, scheduling, and making informed decisions during the project lifecycle.
4. Quality assurance teams: Measuring cohesion and coupling can help quality assurance teams in identifying potential design issues or architectural flaws that may impact the system's performance, scalability, or maintainability. This knowledge can guide their testing and validation efforts.
5. System maintainers: Measuring cohesion and coupling can provide valuable insights to system maintainers, allowing them to understand the existing design and make improvements or modifications more efficiently. It can also help in identifying potential impacts of changes in one module on other modules.
