How do you decompose a large project?

Decomposition of a large project is the process of breaking it down into smaller, manageable parts to simplify planning, development, and control. Main steps:

1. Defining goals and requirements — clearly articulate what the project should do.
2. Breaking into modules or components — identify logical parts of the system that can be developed and tested separately.
3. Decomposing tasks — break each part into specific tasks or user stories.
4. Identifying dependencies — understand which parts depend on each other to plan the sequence of work correctly.
5. Estimating and allocating resources — assess labor costs and assign responsible persons.

For example, in developing a web application, you can distinguish frontend, backend, database, and integrations with external services. Each of these modules is further broken down into specific functions and tasks.
