Explain the advantages and disadvantages of sub-systems in technological systems.
System can get too complex if too many sub-systems included e.g. redundant systems on aircraft
Design
Specialisation can allow development of high quality components at a reasonable price.
e.g. Nvidia graphics cards, Rolls Royce engines for jets, Hella with vehicle lights.
Development
People can be trained relatively quickly to do a job that focussed on a limited range of skills e.g. house building.
But, it may take several teams of people to build a house - not always good.
Maintenance
Sub-systems can be easily removed and replace without interfering with the rest of the system.
