Regarding developmental performance management, it is essentially in the name. Developmental performance management can be considered a specific approach in the sense that it focuses on developing the individual capabilities and skills of employees with the aim of improving their effectiveness in their respective roles and possibly assisting them in addressing weaknesses as well as preparing them for promotion (where applicable). For example, suppose that you hold some sort of a managerial role at a particular business and that your responsibilities include managing a team of employees who report directly to you. You happened to be pleased with the performance of one of your subordinates to the point where you deduce that they have the potential to undertake more complex tasks and make a more substantial contribution to the business (potentially implying the need for a promotion). Developmental performance management would be appropriate in this context.
Conversely, administrative performance management can be considered a more general approach, which encompasses the use of information (which is often gathered following an annual appraisal) by management to plan HR targets, including:
- Training
- Rewards
- Performance
In other words, this model focuses on relevant data collection in order to better manage the HR function, the aim being to closely align individual and business goals, ultimately achieving the strategic goals of the business.
A simple practical manifestation of administrative performance management would be collecting KPI-related information for a recent time period, based on which management could maintain or make changes to particular targets as needed.
I hope this helps!
