The gap analysis also can be used to analyse gaps in processes and the gap between the existing outcome and the desired outcome. This step process can be summarised as below:
Identify the existing process
Identify the existing outcome
Identify the desired outcome
Identify the process to achieve the desired outcome
Identify Gap, Document the gap
Develop the means to fill the gap
Develop and prioritize Requirements to bridge the gap[1]
Gap analysis can also be used to compare existing processes to processes performed elsewhere, such as those obtained by benchmarking. In this usage, you compare each process side-by-side and step-by-step and note the differences. Then analyze each difference carefully to determine if there is any benefit obtained by incorporating the other process or portions of the other process. This analysis must be done carefully and objectively to realize any potential gains. Sometimes the gap analysis will reveal that the two processes can be combined to create a new one that is superior to either original.
