The last factor to consider deals with the experience level of the project team members. This is called the environmental complexity factor (ECF). Take each factor in Table C-4 and assign it a rating between 0 and 5. Consider the following contexts:
For the first four factors, 0 means no experience in the subject, 3 means average, and 5 means expert.
For the fifth factor, 0 means no motivation for the project, 3 means average, and 5 means high motivation.
For the sixth factor, 0 means extremely unstable requirements, 3 means average, and 5 means unchanging requirements.
For the seventh factor, 0 means no part-time technical staff, 3 means average, and 5 means all part-time technical staff.
