How is efficiency of ppc function measured?
Answers
Explanation:
Functions of production planning and controlling is classified into:
Pre-planning function
Planning function
Control function
Production Planning and Control Functions
The functions of production planning and controlling are depicted in the following figure.
PRE-PLANNING FUNCTION
Pre-planning is a macro level planning and deals with analysis of data and is an outline of the planning policy based upon the forecasted demand, market analysis and product design and development. This stage is concerned with process design (new processes and developments, equipment policy and replacement and work flow (Plant layout). The pre-planning function of PPC is concerned with decision-making with respect to methods, machines and work flow with respect to availability, scope and capacity.

PLANNING FUNCTION
The planning function starts once the task to be accomplished is specified, with the analysis of four M’s, i.e., Machines, Methods, Materials and Manpower. This is followed by process planning (routing). Both short-term (near future) and long-term planning are considered. Standardization, simplification of products and processes are given due consideration.
CONTROL FUNCTION
Control phase is effected by dispatching, inspection and expediting materials control, analysis of work-in-process. Finally, evaluation makes the PPC cycle complete and corrective actions are taken through a feedback from analysis. A good communication, and feedback system is essential to enhance and ensure effectiveness of PPC.
