The variables included in the template are generic. Customize the matrix by making the necessary changes to suit your organizational requirements. Have a clear idea on what people do in the organization, and what defines success in the specific context, and incorporate such variables.
Add such new variables to each section, and delete any irrelevant variable. For instance, contributions to team work may be not applicable to employees who work independently. In such cases, eliminate this variable. Similarly, supervisors would require additional variables such as “ability to get work done by others," “interpersonal skills," “extent of empathy toward others" and more in their list of general work related variables.
The “x" axis in the template lists out months by defaults, and is limited to one year. Add more years if required. Change the months to weeks, quarters, years, days of the month, or anything else as required, and if retaining months, add months for any number of years as required.
