71. What is CPM & CM
CPM cost per minute. It may be for a production line, a factory, or an organization.
CPM (Cost per Minutes) = (Direct Labor Cost + Operational Cost) of the month/ Usage Minutes (Available Minutes) of the month
CM or COM is the cost of making or making cost. In a broad sense, it is CMT (Cut, Make & Trim) cost for the garments industry. Before finding CM, CPM must be calculated.
CM= (SMV × CPM)/ Expected Efficiency%
Suppose any item SMV is 5.5, Expected efficiency = 62.5 %, CPM= $0.03
CM = (5.5 × .0264)/ .625
= $0.264/PCs
= ($0.264 ×12)/ Dzn
=$3.168 / Dzn “
72. What do you know about takt time?
The average time between the start of production of one unit & the start of production of the next unit, when these must be set to match the rate of customer demand, is called takt time. In short, it reflects the production rate needed to match the demand.
T=Ta /D
Where T=Takt time
Ta=Net available time
D=Demand
Net available time is the time for work completion, including break time, maintenance, loss time, brainstorming, etc.”

76. What is SMED
SMED (Single-Minute Exchange of Dies) is a system for dramatically reducing the time required to complete equipment changeovers. The essence of the SMED system is to convert as many changeover steps as possible to “external” (performed while the equipment is running) and to simplify and streamline the remaining steps. The name Single-Minute Exchange of Dies comes from the goal of reducing changeover times to the “single” digits (i.e., less than 10 minutes).
77. A successful SMED program will have the following benefits:
1. Lower manufacturing cost (faster changeovers mean less equipment downtime)
2. Smaller lot sizes (faster conversions enable more frequent product changes)
3. Improved responsiveness to customer demand (smaller lot sizes allow more flexible scheduling)
4. Lower inventory levels (smaller lot sizes result in lower inventory levels)
5. Smoother startups (standardized changeover processes improve consistency and quality.

Use the PDCA cycle when
1. Starting a new improvement project
2. Developing a new or improved design of a process, product, or service
3. Defining a repetitive work process
4. Planning data collection and analysis to verify and prioritize problems or root causes
5. Implementing any change
6. Working toward continuous improvement.
79. What is OEE & valuable?
OEE (Overall Equipment Effectiveness) is a “best practices” metric that identifies the percentage of planned production time that is genuinely productive. An OEE score of 100% represents perfect production: manufacturing only good parts as fast as possible, with no downtime.
OEE is helpful as both a benchmark and a baseline:
As a benchmark, it can be used to compare the performance of a given production asset to industry standards, to similar in-house assets, or to results for different shifts working on the same purchase.
As a baseline, it can track progress in eliminating waste from a given production asset.”
80. What types of markers are used
