What prompts a new system?

Feasibility

Technical feasibility
does the technology exist to implement the proposed system, or is it a practical proposition?

Economic feasibility
is proposed system cost-effective – if benefits do not outweigh costs, it’s not worth going ahead.

Legal feasibility
Is there any conflict between the proposed system and legal requirements – e.g. the Data Protection Act?

Operational feasibility
Are current practices and procedures adequate to support the new system?

How will the system change the working lives of the staff involved?

Schedule feasibility
how long will the system take to develop, or can it be done in a desired time-frame?
