What is a most important management skill? Without that skill management is not complete.

Skill in Communications.

Once your skill in communications is developed to a high degree , you can be very effective in any managerial work of your chosen career as your superiors as well as your colleagues can understand your messages very well and instructions to your subordinates  & people are received clearly.

We have to take note that high degree of  communications skill requires the following abilities and attributes;

a) Excellent command of English or the required language or medium of communication in a

company.

b) Can reply appropriately to the question being asked or make comment fitting to the issue being discussed in a meeting or conversation.

Creating work environments to help people work to the best of their ability; supporting and encouraging others; helping others find meaning and fulfillment in work, deal with a variety of personalities.

Management functions: planning, organizing, coordonating, leading, controlling. 

There is no such ONE skill. Without all these skills, one cannot be a manager, but simply an assistant to the one that has the missing skills. 

Team buliding and people development

Management is a set of skills that should be used all together to have appropriate and sufficient outcomes. These skills are connected like a chaine, and missing one might affect others, however If I want to choose one I would say "Decision Making" Skill could be the most important one !

This is a difficult one, as you are asking for the most important! 

I would say PLANNING! 

Without planning, no matter what skills or tools you have, you will always end up messing with the project, either waste time and resources on the start, or deliver late, etc. Therefore, planning is most important to me!
