A working organisation should have aligned the 4 elements. Any change will impact one of those 4 elements.
TASK: What the staff is expected to do. What is the job for each of the roles? PEOPLE: What knowledge and skills people need, and do they require any formal training? How many of them? STRUCTURE: How is the organisation organised. What is measured and monitored? TECHNOLOGY: All the tools, digital and analog that are needed for the staff.
