ICUKU (Impact, Control, Known, Unknown, Uncontrollable) is a 9-square Matrix tool that can be deployed for Categorizing the possible solutions on an Impact Vs Implementation grid. On the "X" axis we Impact categories (Low, medium, High) and on the Y-axis we have Controllable ( further subcategorized as Known and Unknown ) and Uncontrollable factors.
This Matrix will help us to first categorize and then prioritize the factors/solutions ( Vital "Xs" , independent variables ).
The Solutions that have been identified by the teams through various various RCA techniques can then be placed in either of the 9 cells basis the impact that the action may yield on the proposed change and the ease of implementation basis the factors that the team can also attribute the controllable , uncontrollable scope of those known and unknown solutions.
Its becomes very critical that while constructing the ICUKU matrix , the team is realistic and exercises pragmatic approach when placing the solutions in the matrix cells, the success or the failure of achieving the desired results will depend upon the solutions we have identified and then categorized then as accurately as possible.
Resources are limited and cost optimization along with maximum yield in shortest duration of time is what all want to achieve and this exercise will help to deliver to those expectations to an extent if done correctly.
So the Solutions that exist in the HK , MK , HUK, MUK will be our scope of priority in deploying the Actions , to maximize the output.
The Example below for an AHT Improvement project showcases the actions that can be deployed ,where ICUKU will be able to help us in planning our actions for best possible results.
So the Actions in the cells identified as per the first Matrix , should help us identify the actions that are in our control to implement and will yield immediate results compared to rest of the actions identified.
