4 types of feasibility
|
•Technical Feasibility - does the company have the technological resources to undertake the project? Are the processes and procedures conducive to project success?
•Schedule Feasibility - does the company currently have the time resources to undertake the project? Is the project completable in the available time? •Economic Feasibility - given the financial resources of the company, is the project something that can be completed? The economic feasibility study is more commonly called the cost/benefit analysis. Operational Feasibility - this measures how well your company will be able to solve problems and take advantage of opportunities that are presented during the course of the project |
