Answer: d. Unity of direction
Explanation:
The principle of Unity of Direction is one of the 14 principles of Fayol in relation to administration. Summarised into one phrase, the principle would mean, One Head One Plan.
This is because the principle believes that when in a company, different departments aim to achieve distinct goals, the departments should have a sole leader and a sole plan for the goals that should be accomplished so that there is no confusion.
This is why the Akika Corporation wants to create independent domains that reflect the actions they perform and will have the distinct roles needed to help them perform the actions efficiently.
