Decision Analysis Worked Out Example
The governance, Risk, and Compliance (GRC) management system is developed for the IT and ITES domain. The primary objective of the Governance, Risk, and Compliance (GRC) management system is to help companies implement Governance, Quality, and Information Security Management Systems in an integrated manner. It has various features, one of which is to plan and track projects and programs using standards such as CMMI, ISO 9001, and ISO 27001, etc.
Through this example, let us see how the organization comes to a conclusion on whether to purchase the solution or build it in house.
The criteria taken into account and the weightages assigned to each criterion can be seen below:
Adaptability to our needs
Cost of solution
Ongoing maintenance cost
Time to implement
Due to better fitment with organizational needs, it was decided that the system be developed in-house.
Thus, a weighted decision matrix assesses options in which each criterion is weighted based on importance. The higher the weighting, the more important the criterion. In this example, the criteria are weighted on a scale of 1-5, where 5 indicates the best match.
In-house option = 5*5+3*2+3*5+2*2+2*5 = 79
Buy option = 5*3+3*5+3*3+2*5+2*2 = 48
