Excellent The best practices have been implemented and it is fully

Strong System addresses the factor and the best practices have
been used for the best practices.
1 Cause for
Concern
A critical issue has been raised for the development of the
system and the qualification factor has to be addressed. It
is also inadequately used for the best practices.
Recommendation
From the above mentioned scores it is clear that the development of the system by a
vendor is a better option as they would be able to provide a better development option for the
system as the in –house development of the system would not be feasible in terms of
efficiency as required by the organization. The in-house development would also be very
difficult for the organization due to lack of manpower for the development of the system

while on the other hand the outside vendor would be having a suitable team to back the idea
formulated by the organization and implement the system efficiently.
