Explain how the 'separation of concerns' principle contributes to improving the maintainability and understandability of a software system.

Study Notes
Receivables Aggregation
- Compared to automotive industries, contract manufacturing for final assembly is much less prevalent
- Most auto companies have their own assembly plants because product life cycles are longer and demand are more stable
- designing assembly plants for multiple brands is also difficult
- A successful contract manufacturer in automotive is Magna Steyr International from Graz
- The key is to "build up to five different vehicle types/derivatives on a single assembly line."
Sharing Rewards to improve performance
- The success of the process relies on putting in the work to have a aligned incentive, resutling in benefits for all
- A similar situration arrises if the supplier adds cost, shared rewards contract that makes it beneficial for everyone
- Also applied to toxic materials which require the same type of agreement
- In general sharing the benefits is key to align all stakeholders, including penalities for suppliers that dont improve
Warehousing Aggregation
- All requires good info
Quantity Flexibility
- Can be difficult when suppliers want low quality materials
Buybacks
- A downside to the buyback clause (or any equivalent practice, such as holding-cost subsidy or price support) is that it leads to surplus inventory that must be salvaged or disposed
- The task of returning unsold product increases supply chain costs
- The cost of returns can be eliminated if the manufacturer gives the reatiler a markdown allowance and allows it to sell the product at a significant discount
