Here we will share tips of successful event managers with you guys;
1. Plan Early
If you have received a project of event management then start planning for it as soon as possible. Because for larger events it took a lot of time to almost start planning for it 6 months before.
2. Flexibility
Dont behave like a stubborn child, because things need to be flexible. Over the course of the planning phase, things require modification.
3. Negotiation
Everything is negotiable. Determine your costs before vendors come to you and offer a discount of 10-15%.
4. Back-Up plan
Always make sure to have a back-up plan in case something unwanted happens.
