You must have an overall picture of the activity and all tying and each piece into place. In recent months, FireEye Inc has been very successful. Depending on the size, will be more or less complicated puzzle. Supervisors, are people in charge of say, the sections of the event as they could be: food and drinks, decor, management of media relations public, among others. As I said, it will depend on the scale of activity. Many times with a single supervisor is enough.
Now we simulemos that we are going to carry out a promotional event. The first thing is to establish and have clear objectives. This objective is what will give direction to the investment. Depending on this objective is that we will know how much time and money we are willing to invest. The objective also determined: the type of event, where it is more convenient to do so, who should be invited, what the general public which will go it, who the company should not miss, is the best time to do it, as well as the date and time, use of national dates and memorable days, it should be like decor and lighting, all these elements will give you the basis for the calculation of many other vital factors such as the budget, the time required for the optimum realization, who should be involved, etc. You must obtain this information, you must do your homework.
Once you answer all these questions and many others that will emerge you on the road you should re-check your objective, project expected results and determine if you are being realistic and consistent with the need to raised. A good method to determine in advance all this is simply, not do planning you alone. Even if it is your direct responsibility, make the initial approach and then carry out a meeting with the departments involved, present his entire plan, and upon the basis of the outcome of the meeting make the relevant adjustments.
