The specific list of requests on the basis of which the goal will be broken down into parts is determined by the degree of their development and the level of complexity of the project. In most cases, decomposition is carried out on the basis of the following elements:
Functional requirements : what tasks the system should solve, what is its intended functionality, what types of data it will process.
Non-functional requirements : what properties should the system have (user comfort, reliability, performance, protection from external influences).
Limitations and why purchase dentist database from us assumptions : what factors may influence the system during its development or use (technological limitations, compatibility with other platforms, time frames).
When the project being developed is an integral part of a larger system, information about the need for integration with other resources, applications, and databases is one of the mandatory requirements.
Once all the necessary information has been collected, you can begin to divide the overall task into smaller elements or modules, establish relationships between them, and formulate the final result for each component.

Types of decomposition
There are different ways to break down the upcoming volume of work into specific tasks. The main types of project decomposition are sequential, parallel and single-step. The choice of one of them is determined by the manager based on the current situation.
Sequential (step-by-step)
Many goals require a strict sequence of steps to be achieved. Examples of such projects include preparing a culinary dish according to a recipe, creating a printed publication, or completing personal documents.
In other words, sequential decomposition is the division of a process into stages that follow one another. Its scope of application is the execution of complex multi-component operations, where a strict algorithm of actions is important.
Parallel
There is a group of tasks in which the order of steps is not crucial. Packing a suitcase for a vacation, tidying up the bathroom or buying groceries can be done in any order, the result will be the same.

An example of parallel decomposition is a checklist - a list of tasks that need to be completed to achieve a goal, or a list of items that need to be purchased, collected, prepared.
