This is a tricky situation and will occur a lot of times. It is best to 1. Approach with Openness and Respect - It is best to acknowledge the perspective of the colleague Start by acknowledging their perspective to make them comfortable. 2. Focus on the Shared Goal Shift the focus from the disagreement to the objective: "to deliver the right message to the audience". Focus more on the presentation topics, what will be addressed. this will be more crucial, if you focus on the delivery points which are important to the business. The format then should not be so important.

It is not a bad idea to disagree on the format unless there is a pre-defined one. Few steps that I would take: 1. I would place my understanding and logic behind my disagreement. 2. Listen to my colleague's perspective to the approach. (it could even be I would agree if it logically makes sense) 3. Constructively argue for the betterment of the objective of the presentation. 4. Negotiate and confirm the approach to finalize the format. But format is just one aspect of the presentation and there are more things to worry about such as the contents, crispiness, storytelling, right information rightly represented visually so that it appeals to the audience and properly articulates the objective, outcome, and expectations.

This happens most of the time when there is no structured format to present and a pitch is being made either for business development, raising money, selling a business etc. I learnt several years back that before a presentation gets developed one should write one line statement which is the core message of the presentation and then develop the present around it. To choose a format over another the reverse should be done ie whichever format of presentation conveys the central theme best should be the preferred format. If in difficulty, do it to a third party and get the core message received by them and choose the one that is closest to what you want to convey.

It’s not a big deal :) It’s just a formate , as long as the content is clear and meets the training/ presentation objectives so others things can be handled smoothly

Differing opinions in the workplace are normal. Get curious and have respectful conversations around understanding others' points of view. Sometimes, I have learned that my approach may not have been the best either and it's an opportunity to learn new ways to present. Being open to listening and learning is important. Building relationships is important. Decide what price you want to pay when navigating conflict.
