Proper use of animation is the primary reason for Prezi being rated higher in the study. So why did Prezi rate higher in the first experiment? Heres what the authors write, because zuis are defined by their panning and zooming animations—and animation is an ancillary (and frequently misused) feature of slideware—the most parsimonious explanation for the present results is in terms of zuis and slideware in general, not Prezi and PowerPoint. The younger audience group in the first experiment liked the flashy animation. In a business setting, the misuse of animation effects has led some organizations to ban animation. As I pointed out earlier, the attributes that are most important to business presenters, being clear and professional, are the terms associated with PowerPoint. So as business presenters, what should you conclude? The bottom line is that clear, focused, visual presentations are effective, no matter what tool you use.

So what is the overall conclusion? Heres what the study authors wrote, the non- or marginal significance of some between-format comparisons (e.g., powerPoint versus Prezi) is difficult to interpret. We hesitate to dismiss these differences as statistical noise given their general alignment with rating results, as well as the correlation between business decisions and presentation ratings (which do vary significantly with format). For the more objective outcome of decision-making, we can, at the very least, provisionally conclude that Prezi presentations are more effective than oral presentations, and that software-aided presentations are more effective than oral presentations. It doesnt say that one tool is better than the other. What it says is that using software is better than no software and that it is difficult to conclude that there is a true difference between the tools. Presentation medium is not the primary determination of presentation success. The authors go on to get specific about the tool as they wrote, like others 107, we caution against technological determinism: Presentation medium is but one of many factors that determine presentation success, and presentations that rely on any given medium can succeed or fail. The tool is only one of many factors in the success of a presentation. To state that one tool is the key to success is just not accurate.
This was true for 23 of the 24 rating dimensions (visually boring was the exception with the largest effects for ratings of effectiveness and persuasiveness. Those who rejected the offer rated the overall presentation, visual aids, and presenter as less effective than those who accepted the offer, with effect sizes (Cohens d).93,.83, and.78, respectively. These effects were consistent across formats, all interaction.05. For both Prezi and PowerPoint, the key was how good the presentation was, not the tool used. Effective visuals matter when presenting, the study also looked at the specific elements in each presentation. Heres what they wrote, presenters and presentations were rated worse if they had too much or not enough text, and not enough graphs, images, and animations; in terms of audience decision-making, presentations were less effective if they contained too much or not enough text,. Overall, regardless of tool, the effective use of visuals was key. General Discussion, after from discussing the details of the two experiments, the study authors shared some discussion and conclusions. The study did not conclude that Prezi is better than PowerPoint for decision-making.
I look at those descriptors and think that words associated with PowerPoint like professional and clear are ones that match what real business audiences have told me they want in a presentation. Experiment 2, the second experiment focused on how persuasive a presentation was in convincing a different audience panel to make a decision to buy a product. In many business presentations, making a decision is a key component. In the key dimension of helping the audience make a decision to buy, prezi was no more influential you than PowerPoint. In this more important dimension of business presentations, the authors wrote about the findings on which tool was more effective. Heres what they said, Specific comparisons revealed that Prezi presentations were significantly more influential than control presentations, exact p 0003, marginally more influential than oral presentations, exact.06, and no more influential than PowerPoint presentations, exact.39; Clearly Prezi is not more effective than PowerPoint. The key in getting a positive decision was the effectiveness of the presentation, not the tool used. This experiment looked at convincing an audience to make a decision. Heres what the study authors wrote about how much influence the presentation had on the decision, those who rejected the i-mart offer rated presentations as worse than those who accepted the i-mart offer.
Here is what they wrote about this testing, As part of the expertise-related measures for PowerPoint and Prezi, we asked participants to identify whether or not it had particular functionalities (e.g., the capacity to record narration, create custom backgrounds, print handouts). Most business presentations dont include narrating slides, most organizations supply a branded template so most business presenters should never change the background, and pdf files have replaced print handouts. So i am not convinced that the skills being assessed were the right ones to be checking for business presentations. The audience descriptions of PowerPoint presentations are what business presenters want. In addition to numerical scores, the audience participants were asked to comment on the presentations. Heres what the study authors wrote about the written commentary, in explaining their rank-ordering of the presentation formats in terms of their general effectiveness, 8 of participants who preferred Prezi mentioned that it was new or different or that PowerPoint presentations were old or outdated. More commonly, they described Prezi as more engaging or interactive (49 organized (18 visually interesting, visually compelling, visually pleasing, sleek, or vivid (15 or creative (13). Of participants who preferred PowerPoint, 38 described it as more concise, clear, easy to follow, familiar, professional, or organized than the other presentation formats. An equal percentage explained their choice in terms of negative judgments of Prezi, including comments that Prezi was disorienting, busy, crowded, amateurish, or overwhelming.

The mean audience age in this experiment was.4 (source: Table 2). Most business presenters face audiences of executives that are much older, so the evaluation of this young group will likely not be the same as the typical business presentation audience. Most audience members were not business professionals. Of the audience participants evaluating a real-world business presentation, 102 of the 152 (67) were students (source: Table 2). They were asked to play the part of executives in a company, which most would not have any experience.
So i am not sure how much I would trust their judgement of what an effective business presentation would. Older audience members (those who are likely the age of business professionals) preferred PowerPoint. The study authors looked at the effect of audience participant age on the preferences between the tools. Heres what they found, Among demographic variables, only age showed reliable correlations with the audiences evaluations of presentations: the older the participant, the more effective they rated PowerPoint presentations,.23,.007, the more persuasive wallpaper they ranked PowerPoint presentations,.24,.006, and the less organized and. So for the typical business presentation audience of middle aged executives, powerPoint was found to be more effective. As part of assessing how well the presenters knew the products, the questions were on topics not related to most business presentations. The study assessed how familiar the presenter participants were with the tools.
Should business professionals be concerned? Most of what you read in the articles doesnt apply to the presentations you do and the conclusions you see in those headlines may not even be supported by the study. I encourage you to read the study. The study was funded by Prezi, so some might conclude that the conclusions were pre-determined. I believe the authors when they say that they followed all protocols to ensure there was no bias.
I also trust that they did a proper and complete study that followed all guidelines and best practices. The issue i have is with the headlines that have come from a cursory glance at the study results that imply a conclusion that may not be accurate. Here what I picked up as I read the study, specifically thinking about business presentations. The study had two experiments and some general conclusions. Ive listed my thoughts in these groups as the study lists them. Experiment 1, this part of the study focused on comparing PowerPoint, Prezi, and oral presentations. This is the part that some commenters claim proves Prezi is better than PowerPoint. Audience age doesnt match the average age of most business audiences.
Do's and Don'ts of making
The idea is to identify the places where the business logic calls up to ui components to ask the user a question and gather data, and then to encapsulate those into a set of interfaces. Each method on that interface will contain the ui-oriented code from lab the original workflow, and the ui class will then implement that interface. The new code that wants to reuse the business logic in question will also implement this interface, but substitute either new windows or possibly pre-fab or parameterized answers to the questions originally answered by the ui components. This way, the biz logic can be treated as a real library, albeit with a somewhat resume awkward interface parameter passed to some of its methods. Is this a decent approach? How better should I go about this? I will defer to your collective internet wisdom. A recent study has resulted in articles that declare that according to a harvard study, prezi is better than PowerPoint.
Considering a hypothetical situation where an old, legacy presentation library has been maintained over the years, and has gradually had more and more business logic coded into it through a process of hasty corrections and lack of proper division architectural oversight. Alternatively, consider a business class or namespace that is not separated from presentation by assembly boundaries, and was thus capable of referencing something like rms without being forced to add a reference (a much more sobering action than a simple using clause). In situations like this, it's not unimaginable that the business code used by this ui code will eventually be called upon for reuse. What is a good way to refactor the two layers apart to allow for this? I'm loosely familiar with design patterns-at least in principle anyway. However, i don't have a whole ton of practical experience so i'm somewhat unsure of my intuitions. I've started along the path of using the Strategy pattern for this.
