Successful Meetings
As a busy project manager> the last thing you need to happen is being involved in meetings that are unsuccessful to you, in terms of their outcomes. Going in to any meeting you have to know exactly what you need to achieve in it, and take away from it, in order for it to be a successful meeting. So, what can you do to ensure that you achieve your $1meetings objectives?
Personal skills.

Inter-personal skills.
Using a forceful personality, assertiveness>, to effect push something through, should be seen very much as the last resort. If at all possible you need to get others in the meeting agreeing with you and understanding, or at least accepting, that your ideas are the ones needed for the project to progress> correctly. (Notwithstanding of course that others may well make helpful contributions that can be incorporated.) To do this you need to ensure that from the outset of the meeting you have $1established objectives> that are mutually agreeable to all around the table, preferably by building a $1joint agenda>. In doing these things you can be confident that there is common ground on which all the participants will be engaged in. Thereafter - you need to present your case with the degree of $1clarity> with which it was prepared, being quite comfortable in $1maintaining flexibility> to any points made about it, being constantly alert to any negative $1body language or overtones in any responses to your case. Do give time for others to air their views too, but be sure to make your response one that finds common ground between their point and your objectives - in order to $1promote the sense of everyone benefiting from the outcome you desire.
