Critical Path Method and Garmenting
Time consumed in product development (PD) is the biggest issue. Approvals and bulk fabric in-house consumes approximately 75% of the total pre-production activity time and as far the most time-consuming task. Whole supply chain needs a system which
Reduces time spent in PD.
Co-ordinates internally for all pre production activity.
Producing a high quality clear-cut specifications for manufacturing and quality purposes
About 60% of the delays are at pre production stage and remaining at the production stage and reduction of such time can help the company in meeting the delivery dates on time. Controlling the delay would enable the company to reduce the deviation from the schedules lead time and honor the delivery date.
SCOPE OF CRITICAL PATH METHOD
Garment merchandising activities are characterized by people oriented function .
Interdependent activities are synchronized between succeeding and preceding activities to make process network .
Critical chain is the solution the garment industry is looking for as it is based on task dependency.
CRITICAL PATH METHOD
The Critical Path Method, abbreviated CPM, or Critical Path Analysis, is a mathematically based algorithm for scheduling a set of project activities. It is an important tool for effective project management. The essential technique for using CPM is to construct a model of the project that includes the following:
1. A list of all activities required to complete the project (also known as Work breakdown structure),
2. The time (duration) that each activity will take to completion, and
3. The dependencies between the activities.
The shortest time possible to complete the project.
The longest path of planned activities to the end of the project.
The earliest and latest that each activity can start and finish without making the project longer.
Which activities are “critical” (i.e., on the longest path) and which have “total float” i.e., can be delayed without making the project longer.
