Technical feasibility
◦ Is the solution technically practical?
◦ ؟ﺔﯾﻧﻔﻟا ﺔﯾﺣﺎﻧﻟا نﻣ ﻲﻠﻣﻋ لﺣﻟا لھ
◦ Does our staff have the technical expertise to design and build this solution?
◦

◦ “Technical feasibility study is the complete study of the project in terms of input, processes, output, fields, programs and procedures. It is a very effective tool for long term planning and trouble shooting. The technical feasibility study should most essentially support the financial information of an organization.”

◦ Operational feasibility determines if the human resources are available to operate the system once it has been installed
◦ Users that do not want a new system may prevent it from becoming operationally feasible

Estimating Time
Project is broken down into phases
Further broken down into tasks or activities
Finally broken down into steps or even smaller units
Estimate time for each task or activity
May use a most likely, pessimistic, and optimistic estimates for time
