The ability to organise is useful in any job. It’s essential if you have any kind of management responsibility. Basically, being organised means understanding the resources you have available to do a task and then putting them to work in the most effective and efficient way. These resources could include time, people, money, opportunities or equipment.
Organised people make plans and think ahead. If something goes wrong, they already have an idea of how to fix the problem.
If you can already manage your own time well, you will probably be quite good at organising your job. If your usual approach to life is more unstructured (or even chaotic), you will have to put more effort into acquiring this skill.
