Functions of Production Planning and Control in Garment Manufacturing

Production planning and control (PPC) department is one of the most important departments in garment manufacturing industry. It plays an important role in apparel production. Because the highest efficiency in production is obtained by manufacturing the required quantity of product at the required quality and required time by the best and cheapest method. This implies the necessity of the harmonious implementation of PPC functions.

Functions PPC department in apparel industry:
The main functional parameters of production planning and control in garment manufacturing industry can be classified in 10 categories:
Functions of production planning and control

Each functions has been explained briefly just overview about the task.

1. Materials:
Raw materials, finished parts and bought out components should be made available in required quantities and at required time to ensure the correct start and end for each operation resulting in uninterrupted production. The functions include the specification of materials (quality and quantity), delivery dates, variety reduction, procurement and make or buy decisions.

2. Methods:
The purpose of this function is to analyze all the methods of garment manufacturing and to select the best method according to the given set of circumstances and facilities. It determines the sequence of operations and the division of product into assemblies and sub-assemblies, modified by the limitation of existing layout and work flow.

3. Machine and manpower:
Methods of garment manufacturing have to be related to the available production facilities coupled with labor and a detail study of equipment replacement policy. Maintenance policy, procedure and schedule are also functions connected with managerial responsibility.

4. Routing:
The flow of sequence of operation and processes to be followed in manufacturing a lot is routing. Routing determines what work will be done on the product or parts and when, where and how it will be done. It estimates the garment operation, their path, sequence, proper class of machines and personnel.

5. Estimating:
Once the overall method and sequence of operations are fixed process sheet for each operation is available, then the operation times are estimated. Apparel estimation is carried out using extensive analysis of operations along with methods and routing and establishing a standard time for operation using work measurement techniques.

6. Loading and scheduling:
The schedule is a detailed plan for an immediate and relatively short time period. It requires greater importance in manufacturing. Machines have to be loaded according to their capacity and performance.

7. Dispatching:
It involves assignment of work to different machines or work places to release the order. It is an important step as it translates production plans into reality or physical work.

8. Inspection:
It involves the activities that ensure the quality of goods.

9. Expediting:
It involves following up the parameters which regulate the progress of materials and parts through the production process.

10. Evaluation:
A thorough analysis of all the factors influencing the production planning and control helps to identify the weak spots. However, the corrective action necessary to overcome the discrepancy will be affected by a feedback.
