Assumptions and Constraints
Assumptions and Constraints – Many projects begin with limited accuracy. Only a few of them begin with adequate certainty. Some issues and facts are known at the beginning but most isssues and parameters must be estimated during the planning phase. Successful project managers and business analysts keep in mind the effects of assumptions and constraints while managing their projects. In this article we will review the concept Assumptions vs Constraints
An assumption is something that is believed to be true based on our knowledge, experience and information provided by our team members. These are anticipated events or issues that are expected to occur during our project’s life cycle.
Assumption analysis is a part of risk management process. If it is not made properly analyze, it may affect the projects health.The project management plans need to changed if assumptions are verified wrong.
Project constraints are anything that restricts or dictates the actions of the project team such as the limitation of cost, schedule, resources. Projects must be executed within the boundaries restricted by the constraints.
All of the six constraints influence each other in that any one getting affected impacts one or more of the rest.
A constraint can be of two types
1. Business Constraints
2. Technical Constraints
Business Constraints focus on the available time, money and resources for a project. Common business constraints include resource limitations and budget and time restrictions.
Technical constraints focus on architecture and engineering decisions that limit designs. For instance, we’re constructing an abutment, and according to the design our abutment should be able to withstand a certain amount of pressure. This pressure limit is our technical constraint.
It is important to define, analyze and document project assumptions and constraints so that as the project progresses the project manager is able to verify and validate the accuracy of assumptions and capture lessons learned. Assumptions and Constraints are inputs to many project management processes.
