CM Variance

Unit Wise CM Variance

Buyer Wise CM Variance

Average Marketing VS Average Used CM

Average Plan Target VS Average Used CM

Findings from Analysis

• CM loss at Marketing  $3,933.0123 [Dec’18-Feb’19]. Only Buyer ‘Promodoro’ Marketing CM gain $5.8259.
• Average Marketing SMV & Average Sewing SMV difference 0.21. SMV used in production less than Marketing, which is a positive fact to gain profit.
• CM loss of Unit-01 & Unit-03 in production, use of more manpower than Marketing, the achievement of less efficiency than Marketing are the reasons for the loss in CM.
• In Unit-02, efficiency gain (52.08%) is more than expected (43.08%) but used CM is more than Marketing & Less than Plan target CM.  If there was no loss during Marketing, CM gain would be profitable.
• Efficiency variation avg 2.40% than expected which results in total CM loss.

Feedback from Analysis

• CM based target need to establish for-profit gain in CM.
• The capacity calculation/ projection should be followed by CM considering SMV, Manpower, Working hour, Efficiency as well as Quality.
• CPM should be standardized/similar for all buyer & all units.

The Necessity of CM Based Target Set-up

• Currently, Garments profit calculation based on FOB. But in practice, it is the total performance of Textile, Fabric finishing, sewing, printing, embroidery, Garments finishing, logistics, etc. & investors profit percentage, deficiency cost.
• Profit calculation & evaluation will be equal for all units.
• CM based target can be used for other units like Textile, AOP, Finishing, Dyeing, etc. to measure performance more precisely.

Pre-activities for CM Based Capacity Allocation which we Want to do for Future

• Production floor should be Industrial Engineering database controlled.
• 6S/7S Training & auditing system should be established for all employees of all departments.
• Floor IE must know operation breakdown, CM & Efficiency analysis.
• Line balancing, workstation standardization, lean management training needed for IE & production people also.
• No modification in Line layout (SMV, MP, M/C) will happen by approval of Corporate IE department.
• The cutting section should be IE based CM calculation to improve efficiency & gain profit from Cut-make section.
• Finishing section should be IE based CM calculation to improve efficiency & gain profit from the make-trim section.
• The textile sector should be IE based to reduce re-process & re-work. In the long run, it will gain more profit from the textile sector.
• Printing IE activities will be vast to CM based capacity allocate for making it more precise in profit gain & efficiency achievement.
• Other production units need to Industrial Engineering controlled to achieve target efficiency & profit.

A Positive Outcome from Proposed Implementation Ideas

• There will be no CM loss during marketing stage. Use of similar CPM will lead the marketing team to work for plant target CM wise order taking.
• CM loss will not happen in the production stage with proper manpower utilization, efficiency achievements; quality products by IE based production system.
• CM profit is the core profit percentage of FOB & our factory profit margin will increase by proper implementation of IE-based activity in every sector.
