Mistakes in Communication & Vendor Coordination
Communication is the fundamental element in events. Without it, the entire event can fall apart. Let’s examine some common mistakes in communication and vendor coordination.

Miscommunication with Vendors.
Suppliers are late. Equipment is never delivered. Catering orders are incorrect. Most of these nightmares are often caused by miscommunications.
Hence, write everything down. Confirm in advance. Follow up from time to time. Avoid vendor communication mistakes to save yourself from a great deal of embarrassment.
Unclear Roles for Team/Volunteers
Checking in guests, managing VIPs, and monitoring the sound systems are all tasks that you need to complete. If nobody is appointed to these tasks, your event can become a complete mess. The chaos at the event can even become difficult for you to handle.
Hence, team coordination in event planning is of great importance. Even the simplest events deserve detailed planning with all tasks assigned.
No Risk / Contingency Planning
When a microphone dies, there is no need for panic. If the projector won’t connect, it’s okay because a backup plan is in place. If it rains in the middle of your outdoor wedding, don’t worry. These are all typical issues. Forgetting to establish a plan B is the real failure.
You must know how to manage vendors in event planning, especially when preparing for a backup plan. Hence, you must have spare equipment, other venues, and even alternate schedules to handle any mishap.
Mistakes That Impact Attendee Experience
The experience of the attendees makes or breaks your event. Even if you make a small mistake while planning or executing, it will cast a negative impression on your attendees. Below are the common mistakes that can impact attendee experience.

Ignoring Audience Needs
There is everything wrong with the approach of trying to please everyone without defining the target audience. Blocking all networking opportunities at a corporate event frustrates employees. A family event with no kids’ activities is the same as taking a half-finished painting to an art gallery.
Without understanding the event audience’s needs, you can end up providing the wrong food and seating that is uncomfortable. What is important is that these fundamental things should be the basis of your plan.
Our piece on marketing strategies for event planners will give you practical methods to enhance participation and create memorable experiences.
Poor Attendee Engagement Design
There is a common misconception that people attend an event solely to sit. Long speeches or poorly designed slideshows, paired with low attendee interaction, can cause boredom. The audience can find it challenging to escape lethargy. This is one of the simplest event engagement mistakes.
Engagement doesn’t have to be difficult. You can engage the audience using techniques such as live polling, icebreakers, moderated Q&As, or even a dedicated event hashtag for social media.
Neglecting Accessibility & Inclusivity
Apart from being unethical, excluding guests is really bad for your business. No wheelchair access, inadequate signage, no dietary considerations, no interpreters, and so on.
If you overlook the factors required for inclusive event planning, you tell your audience that you don’t value them. Such event accessibility mistakes are significant enough to damage your reputation.
A personal experience: At a local art exhibition that I organized, I was told that one young lady needed a wheelchair ramp. Despite not having one in place, I rushed in and found a portable ramp. It didn’t cost me much. However, it made a huge difference. This is when I learned the importance of inclusive planning.
Venue & Logistics Mistakes to Dodge
The entire event logistics planning is about a smooth flow. Access to facilities, seating arrangements, and flow of movement all need to be considered while selecting a venue. If not, guests will be irritated and planners will feel ashamed.

Selecting the Wrong Venue
Disorganized venue selection can get you into big trouble. For instance, having a mini concert inside a large hall,, not having enough parking,, or having a very poor sound system.
These are all common event venue mistakes. When selecting an event venue, you must consider the size of the audience, accessibility, and the facilities available.
Inefficient Check-In Processes
The first impression people get about the event is often influenced by the venue’s entrance. Smooth and quick entry increases confidence in the event. On the other hand, long and complicated lines kill the first impression.
Ignoring Nearby or Competing Events
Having a concert on the same night as your fundraiser is an example of poor venue selection. It heavily impacts the attendance. So, when choosing the right venue for event planning, think beyond the four walls.
Mistakes in Follow-Up and Feedback
Hence, according to acumenintelligence around 92 percent of marketers are focusing on improving post-event engagement. Feedback is essential for improving performance. If you don’t use it, your growth can slow down.

Forgetting Post-Event Communication
The closing of an event does not need to mean the end of the relationship. What better way to stay on top of someone’s mind than sending some thank-you notes or highlight newsletters?
Failing to communicate after an event is one of the most basic post-event mistakes that people make. They end up missing a chance to deepen the relationships.
No Feedback or Analysis
You don’t learn anything without surveys or debriefs. You expose yourself to the possibility of repeating the same mistakes.
The importance of event feedback is evident from the fact that it is the most cost-effective means to achieve growth. It is quite obvious why feedback matters in event planning. It is how you plan to improve next time.
Not Building a Community
It is a fact that the proper execution of events helps to foster relationships. If you are unable to connect with the people after the event is over, you might lose potential repeat clients. A skilled event planner would never miss an opportunity to build long-term relationships.
