If you take a ready template with http://www.pptstar.com/, then 30 minutes. If everything is done by hand and draw a background of the picture, and the week will be enough.
Building the 10 slides (I assume we are looking at a 45-60 minute presentation) should not take more than an hour or two as long as:
- You already have your storyline sorted out
- You have a good idea of how little text to put on the slides (it's easy to write a dozen lines to transmit an idea, it's much harder to use a picture or just a couple of key words)
- you have your image resources (photos, graphs, cartoons, etc) already to hand.
From start to finish (from idea to white paper to storyline to presentation) takes me anything from half a day to 3 weeks depending on the topic.
So I guess I'm saying "it depends" :D
Recommended reading though is Nancy Duarte's brilliant book "Slide!ology"
The real question you should be asking is what do I put on those 10 slides and in what order do I deliver my message?
I teach a very specific 10 slide format that works well for Federal prospects and for teaming as a sub contractor with other firms.
You start with a short intro about your firm and why are you are there and you wrap up with a next steps and thank you. The eight slides in the middle are the key pieces where you explain the opportunity or the problem you can solve, your core capabilities, your key differentiators, and the results your audience will get from working with you.
You should also follow the "rule of 6's" on each slide: no more than 6 bullets per slide and no more than 6 words per bullet point.
A good slide presentation of 10 takes me about 1 to 2 hour depending on the graphics, images and any videos
It depends what you mean by "make", Chris. If I am simply creating slides to go with material I've already developed, this could take 10 minutes (simple background reinforcement of the topic) to an hour (detailed information on-screen for complex topics like insurance training).
If you are including the development of the topic, itself, and not just the slides, this is an unanswerable question, since 10 slides could be 30 minutes or it could be 3 hours, depending upon the topic. Furthermore, the time to develop a topic depends upon experience with the topic. I can deveop a 3-hour workshop in a couple of hours if all I'm doing is reorganizing information I've presented before and am an expert on. For a new topic, it may take me hours to craft just the right presentation for a 30-minute spot.
If all the Data and information is available it should not take more than 90 minutes max.
This truly depends on understanding what the key points are that you are trying to get across in your presentation. It also depends on knowing your target audience, which can give you a better understanding of what content they may want to know. I've made presentations for various situations (academic and industry) and that is key in my opinion. I also think that each presentation is unique so having a time limit on it is relative. However, once you do one presentation and have a template you like, it can become quicker from there.
I think "Good" is a relative term to what the objective is. If you are well prepared and have a solid outline with a clear concise message, the presentation can be completed rather quickly.
If you really want to learn how to effectively give a presentation, I would read "SPIN Selling by Neil Rackham". It helped me develop a sales strategy that made presentations a thing of the past.
Best of Luck!
It really depends on your pace. Are you doing 1 slide per minute of talking, or 1 slide for 10 minutes of talking? The design and approach is different.
When I make slides for myself, I average about 10-15 minutes per slide, which covers 3-5 minutes of talking. This includes fitting into a "script", digging up images or research data, formatting, and proofing. If I'm going to spend more time talking on a slide, I tend to spend more time preparing it.
