Chapter 9 -
Evaluating Third-Party Products
Determine Impact to the
Information Technology Support Infrastructure
-
If the product requires support from the development area, can the
application personnel effectively administer the selected product?
-
Risk vs Benefit. Is the additional
functionality/competitive advantage worth any additional risk the
product brings to the business or IT units? This is often described
as the comfort ratio.
-
Identify changes to the organizational
infrastructure required to support the product (staff additions,
training, etc.)
-
Identify changes to other technologies and
products.
-
Identify additional products required to
support the selected product.
-
Identify changes to existing technologies and
products the selected product will require.
-
Identify changes to policies and procedures the
selected product will require.
Analysis Evaluation
The analysis evaluation determines the
resources required to evaluate, select, implement and support the
selected product. Some problems may not be cost-effectively solved
by existing technologies. Evaluation personnel must estimate the
costs required to evaluate the competing products. In other words,
don’t spend $100,000 to evaluate a $1,000 product. As a rule of
thumb, the evaluation, selection and procurement costs should range
from three and ten percent of the project budget. The time required
to perform the evaluation is also determined during this phase.
