Production planning and control (PPC) organizes and plans manufacturing processes to achieve quality, quantity, time, and place goals through balanced resource utilization. PPC objectives include ensuring quality output, maximizing resource use, maintaining flexibility and inventory levels, and increasing efficiency. The PPC process involves planning, routing, scheduling, dispatching, follow-up and expediting, and inspection. Planning defines inputs and gathers data. Routing defines production sequences. Scheduling determines operation times. Dispatching selects vendors and releases plans. Follow-up regulates progress. Inspection checks and documents quality. PPC is limited by assumptions in forecasts and dependencies on external factors.

2. What is it?
Production Planning & Control is the organizing
and planning of manufacturing processes.
It ensures economic & balanced utilisation of
resources to achieve the desired manufacturing
results in terms of quality, quantity, time and
place.
“What work shall be done, How the work shall be done and
When the work shall be done ”

3. Objectives?
➔ to ensure quality output
➔ to ensure maximum utilisation of all resources
➔ to maintain flexibility in manufacturing operations
➔ To maintain optimum level inventory
➔ To increase overall efficiency

Process

5. Planning
It is the base of PPC
It answers “What shall be done..”
Involves design discussions, finalizing
inputs and gathering data.
Quality of Inputs
matter a lot

6. Routing
Defining the process and sequence of
operations to be followed in production.
It answers “How shall be done..”
We must choose best and cheapest
sequence of operations.
Involves discussion with
vendors/suppliers.
Requires a lot of
thought process

7. Scheduling
Determining the time & date for
sequence of operations.
It answers “When shall be done..”
Involves assigning priorities to the
operations.
Critical! It has cascade
effects on the whole process

8. Dispatching
Vendor selection.
Ordering of plans to be executed.
Releasing of drawings and process
sheets.
Vendor selection
is very important

9. Follow-up & Expediting
Regulating the progress throughout the
process.
Identifying & removal of bottlenecks.
Documentation of changes &
modifications.
Be ready for quick
troubleshooting

10. Inspection
Checking the quality of work.
Documentation of Inspection reports.
Comparison between attained and
desired quality.
Inspection is to be carried
out on Input as well

11. Limitations?
➔ Based on certain assumptions and forecasts
(customer’s demand, availability of materials)
➔ Process is time consuming (scheduling and routing)
➔ Dependency on external factors
