4 Major Causes of Project Changes
Performance variation is an inevitable component of project work and can be used by several common factors. Here are some of the causes of project changes.
#1 Inaccurate initial changes
There are many reasons why initial time and cost estimates for completing the project work prone to be inaccurate.
These reasons may range from lack of experience, lack of information, or importance to inaccurate data, excessive optimism, technological difficulties, and unreliable resources.
Getting those original estimates to be as realistic and accurate as possible makes the control process more manageable.
#2 Speculation changes
The project can open up new avenues of development and design that were not considered during the initial planning of the project work and scope.
New options from a product or service become apparent, customers, sponsors, or the project manager may broaden the project’s scope to include new specifications and deliverables.
#3 New regulations
As project work is progressing, new government or industry-specific regulations may be enacted. This can be especially true for very lengthy projects. If the new regulations are related to ongoing projects, project changes become necessary.
Accommodating new regulations or legislation can also mean revisiting the planning process to determine the effect of the new regulations will have on resource needs, schedule duration, and quality specifications.
#4 Mixed requirements
Many times the requirements are identified by reviewing the documentation and interviewing the end-users and policy makers . However, there are times when complete and comprehensive understanding may not be possible.
For example, even though the interviewer feels that he or she has expressed everything significant, there still may be no meeting of the minds.
Although an RTM is prepared, the same confusion may arise in a written document. Even, prototyping demonstrates the functional and technical requirements of the project.
Although all these techniques reduce the chances of missing any requirements, they cannot guarantee that every requirement is captured. In most cases, there are some discrepancies that surface at different phases in the project.
