Hi,
As usual, no predefined framework that can be used everywehere. Common sens will for sure help more :)
If looking for cost reduction, you need to understand :
- what are the main cost of the company : so you need to understand the activity and think about the cost structure it involves. Depending on the business you could identify this with the value chain and / or the type of cost identification (labor, raw material, etc.)
- Focus your effort on the biggest cost categories : this will create more impact in absolute value. eg. 20% saving on 100M€ is better than 20% savings on 1M€ :)
- tackle each category one by one : starting with the biggest cost buckets
Hope this helps
Best
Benjamin
