Factors in choosing a software process
Choosing the right software process model for your project can be difficult. If you know your requirements well, it will be easier to select a model that best matches your needs. You need to keep the following factors in mind when selecting your software process model:
Project requirements
Before you choose a model, take some time to go through the project requirements and clarify them alongside your organization’s or team’s expectations. Will the user need to specify requirements in detail after each iterative session? Will the requirements change during the development process?
Project size
Consider the size of the project you will be working on. Larger projects mean bigger teams, so you’ll need more extensive and elaborate project management plans.
Project complexity
Complex projects may not have clear requirements. The requirements may change often, and the cost of delay is high. Ask yourself if the project requires constant monitoring or feedback from the client.
Cost of delay
Is the project highly time-bound with a huge cost of delay, or are the timelines flexible?
Customer involvement
Do you need to consult the customers during the process? Does the user need to participate in all phases?
Familiarity with technology
This involves the developers’ knowledge and experience with the project domain, software tools, language, and methods needed for development.
Project resources
This involves the amount and availability of funds, staff, and other resources.
