Project Assumptions refer to any events and circumstances that are expected to occur throughout a project to protect this project from possible risks and issues. They define accepted causes and relationships of project risks and simulate different realities or possible situations that may be favorable to the project. As a rule, project assumptions are accepted as true, without any proof or demonstration. They are outside total control of the project team.
Project assumptions are the basis for creating "what if" scenarios. A thorough analysis of assumptions helps identify the driving force that determines project success. Assumptions analysis along with project scenario planning is used to state assumptions and determine their accuracy and impact. Both activities aim to identify and reduce all potential project risks.
Assumptions are made to any object related to a project. For instance, business requirements, technology, customer expectations, product features, schedules, etc. There are 6 common categories of assumptions such as:
