to determine whether it is sensible to develop some system. The most popular
model of feasibility study is "TELOS", standing for Technical, Economic, Legal,
Technical Feasibility: does the technology exist to implement the proposed
system? Is it a practical proposition?
Economic Feasibility: is the system cost-effective? Do benefits outweigh costs?
Legal Feasibility: is there any conflict between the proposed system and legal
requirements, e.g. the Data Protection Act?
Operational Feasibility: are the current work practices and procedures adequate
to support the new system?
Schedule Feasibility: can the system be developed in time?
After the feasibility study, the requirements analysis should be carried out.
