In our approach we used the same methodology we adopted in analyzing the 2000 Edition.
This methodology shows how process analysis can be simplified if process relationships
are presented in terms of process inputs and outputs. Doing this opened the door for a wide analysis of the context of inputs and outputs.
The assessment of context was achieved by answering a variety of questions
related to each input and output, such as:
- Can we differentiate each component?
- Is this set of components sufficient to continue to the next process?
- Do we need all listed components for a particular input set?
- Is it necessary to generate all listed components for a particular output set?
- Do we need all relationships listed for a particular component?
- Do we need to relate a particular component with some other process?
- What other outputs can be generated with the same set of inputs?
- What can be reduced, grouped, removed, introduced, etc., to make a process acceptable?
Consequently, knowing the context of inputs and outputs, it was possible to develop a sequence of outputs/inputs and also to complete a sequence for processes and process groups defined in the 2004 Edition.
An important part of the methodology was to reveal how feed forward and feed back exchanges of information take place between process groups. Understanding how information is constantly exchanged between process components was crucial to determine how each component can be updated.
A source methodology for establishing relationships, sequences and updating procedure for components of the latest Guide, was the network planning technique. Special attention has been given to adopting a set of rules for coping with a particular situation.
Finally, we have made a statistical examination of events to indicate the magnitude of some of the changes between different editions of the various Guides.
