Hi Nelly and Rajesh!
Developing a competency matrix would involve processes such as:
Job Descriptions: As rightly pointed out by Rajesh, you begin with a job description of the different technical and commercial positions existing in your organization. The job descriptions should specifically focus on the primary and secondary roles and responsibilities that the position demands and the KSA (knowledge, skills & attitude) required for the position.
Developing a competency dictionary: By conducting BEI/semi-structured interviews, you can develop a comprehensive dictionary of generic, functional, technical, and leadership competencies. In the dictionary, you would be defining the competencies.
Competency Profiling: Once the competencies are defined, 3-4 competencies can be clustered into one specific competency cluster, and then you can define the proficiency levels for each competency existing in the competency cluster.
Role Fingerprinting: Once the competency profiling is done, you then define the proficiency levels of the competencies for each level.
Competency Mapping: Once the role fingerprinting for each position is done, then all the employees at that level are mapped for those competencies as against fingerprinted ones. Some of the tools used during the process include psychometric tools, technical tests, and other role-based interventions.
And then you identify the competency gaps, and accordingly, interventions are designed.
Thus, the process of competency mapping is completed, but it is a more permanent intervention, generally lasting over more than five years.
I hope I have been able to explain the process briefly. In case you require additional information, kindly revert back.

Shweta
