Answer: C

"Assumptions are made when adequate information is not
available. When an IS project manager makes an assumption,
there is a high degree of risk because the lack of proper
information can cause unexpected loss to an IS project.
Assumptions are not based on "

known"

constraints. When constraints are known in advance, a
project manager can plan according to those constraints
rather than assuming the constraints won't affect the
project. Having objective data about past IS projects will
not lead to making assumptions, but rather helps the IS
project manager in planning the project in a better manner.
Hence, if objective past data are available and the project
manager makes use of them, risk to the project is less.
Regardless of whether made by qualified people or
unqualified people, assumptions are risky."
