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.
