I have been fortunate to have 10 years as an Organizational Analyst specializing in Job Evaluation (with exposure to Peromnes, Paterson, Hay, Task as well as the 1984's USA State Department's Post Classification System - adopted by a Steel Company with over 15,000 employees). From there, I moved into Quality Management Systems (15 years in both automotive and non-automotive environments).
Advice on Quality Management Systems
My advice is to use the process-approach as advocated by the ISO 9001:2008 QMS standard and to ensure that these 'functional' responsibilities are encapsulated into the organigram and then from there into the relevant Departmental Head Job Profiles. These should be cascaded downwards to the subordinates as required by your company (keep in mind Lean Organization Lessons). Succession planning plays a crucial role for key/critical positions and has been neglected since the 90's when companies felt they could just "buy" talent and not nurture it. The newly emerging title of Talent Manager and the exorbitant salary of such a position demonstrate the failure of reducing Job Evaluation to Salary Surveys and market-related recruiting. One such author, circa 1994, had a chapter in his book, Job Evaluation RIP, which advocated the demise of Job Evaluation.
Aligning Job Evaluation with ISO 9001
I believe that Job Evaluation is coming full circle again, but the approach needs to be aligned to the ISO 9001's process ownership approach. Few HR managers or HR Consultants understand this, and in many companies, I have witnessed dual systems created, thus creating conflict between HR and Quality Management due to this lack of understanding and lack of integration between the two disciplines.
Defining Roles with Key Performance Indicators
Key Performance Indicators (Company Dashboard) and the development of a KPI tree per Function should be the tool to define roles and responsibilities within the Job Description/Profile.
Hiring Initiatives and Group Dynamics
Hiring initiatives should consider influences of Group Dynamics and Personal Profile Analysis (with JPA), either Thomas International or Carlton Publishing Company. Other similar instruments based on research into the 4 Temperaments of Hippocrates (i.e., Brain-dominance theory) should also be considered once the organizational structure is in place. This is because employees get hired for CV-qualification implied competence but fired for performance, and such behavioral identification instruments reduce this risk.
I trust these thought-starters will be of some assistance.
