ActivitiesProcessOutcome

Start of Production Planning• Forecasting Decision: Based on Sales Estimates.• Management Decision : Based on Demand

Estimates, product design, etc.•

Engineering Decision : Based on manufacturingdesign, process design, materials required, etc.• Capacity Decision : Based on existing resources of

plant, machinery, tools, Planning the facility, etc.•

Financial Decision : Based on funds, profitability.• Resource availability :Employee workflow,

availability of skilled labour, etc.

• At office level – Printing & stationery, Brooms,Dusters, etc.

• At selling & distribution level – Packingmaterials, printing & stationery, etc.

Examples of Indirect labour

• At factory level – foremen’s salary, worksmanager’s salary, gate keeper’s salary,etc.

• At office level – Accountant’s salary, GM’s

salary, Manager’s salary, etc. • At selling and distribution level – salesmen

• At office level – office rent, office insurance,office lighting, etc.

• At sales & distribution level – advertising,show room expenses like rent, insurance, etc.

Output of Cost Planning

• Know the value addition at each stage ofproduction.

• Break up of material, production andoverhead costs. Know the direct / indirectcosts.

• Know the cheapest production line.•

Analyse the profitability of make / buydecision.• Know the reason for rise in costs.
