Weighting Project Participants

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.

Table C-4. Weighting Factors for Project Participants
Technical Factor Weight Rating Extended Weight (weight x rating) Reason
1. Use of a formal process 1.5 3 4.5 Project team has average experience with using the Synergy Process.
2. Application experience 0.5 5 2.5 Users are very knowledgeable about Remulak's needs.
3. object-oriented concepts. 1 0 0 The development team and users have virtually no knowledge about
4 Lead analyst capability 0.5 5 2.5 The lead analyst must be very competent.
5. Motivation 1 5 5 There must be high motivation to get the project up and running.
6. Stability of requirements 2 5 10 Requirements must be unchanging.
7. Number of part-time workers -1 0 0 There must be no part-time staff.
8. Difficulty of programming language -1 3 -3 Visual Basic is very easy to learn and apply, but the staff isn't very familiar with it.
E factor   21.5  

  • For the eighth factor, 0 means easy-to-use programming language, 3 means average, and 5 means very difficult programming language.

The total extended weight for all environmental factors is called the E factor. Now that we have this value, we plug it into a formula to obtain the environmental complexity factor: ECF = 1.4 + (–0.03 × E factor). For Remulak Productions, we get the following:
