If you are in charge of organizing a corporate event here are some key elements you will want to take into account before you get started:
Make sure you know who it is that you are talking to. You need to define the target audience as sharply as possible so you can adapt the event architecture to specific traits. Age, education, culture, social habits, relation to the company are a few elements to define and consider before proceeding with any plan.
Type of event
Is it an annual partner business dinner or the training for new employees? Is it a team-building get together or a fundraiser? You have to define the type of event you are handling.
The execution team and their responsibilities
You do not want surprises. So the key element in planning is assigning a defintive role and responsibility list for each of the ones involved in planning and executing the event.
You want to prepare a document with the scenario of the event as you see it from backstage. This document states to do lists, times, responsible person, backup, even crisis communication.
Get aligned with your peers and managers in terms of deliverable and key performance indicators (KPI). If you succeed you need to define success. If you fail you will want something to measure up against for a future growth plan. Make sure you know and understand what it is that is expected of you.
