A research paper I published on Project Escalation and causes for a specific project where I was leading testing side.
It is not a very odd thing for Information System projects to go over budget. Furthermore these projects can reach a point where the cost of the project has surpassed the expected utility, where still investment keeps on going. The phenomenon is known as project escalation. Researchers have identified what are the possible causes of a project to escalate. Apart from some fundamental points, there is variation in the total sum of all forces acting upon the project management team. As the research has evolved, it is understood factors from inside the company are playing an important role such as culture.
