# Planning Process

This chapter provides a comprehensive overview of the entities and objects we have delineated to encompass all facets of software development and delivery, including the actual process itself.

#### A quick overview

* **Tasks** \
  Tasks are our smallest entity, describing a requirement, issue, or change request. They are assigned to releases and developers for implementation.
* **Release**\
  A software release is the sum of the stages of development and maturity for a piece of computer software. Releases continuously increase the feature set of your application without prolonging the wait.
* **Estimation**\
  Estimation in software development refers to the process of predicting the most realistic amount of effort (usually in terms of time or manpower) required to develop or maintain software. Proper estimation is crucial for planning, management, and setting stakeholder expectations.\ <br>
