Project decomposition levels

[Mimaktsa10]

Ideally, the overall goal is broken down into elements to the extent that their full implementation, testing and management are possible. When determining the levels of project decomposition, one should proceed from its scale, complexity and specificity, and also take into account the professionalism of the team of performers.

Breaking down a goal into too small tasks can lead to excessive management and unjustified growth in implementation costs. On the other hand, an insufficient level of decomposition can cause loss of control and increased risks in achieving the desired result.

The optimal solution would be to divide the goal into separate components, taking into account:

Project features : if it is simple belarus email list to implement and small in volume, decomposition can be quite rough. For large-scale projects, serious detailing of tasks with the construction of a hierarchical structure is necessary.

Number of performers : the more people involved in the project, the more specific the tasks assigned to them should be. This increases management efficiency and avoids duplication of functions of individual team members.

Project risks : at a high level, decomposition should be more detailed, which will allow you to control the solution of each task and minimize the risk of failure at any stage.

Decomposition is considered to be carried out at an ideal level if the manager has achieved a compromise between management efficiency, risk control and achievement of project goals.

Before you begin the process of breaking down the goal into smaller tasks, you need to study all the requirements to determine the future components and systems and the principles of their interaction.

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 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.
