If you don't have experience creating presentations and designs, there may be several design rules that you are not aware of like what colors to avoid or which fonts are illegible; also, you may not have access to a graphics library. On the other hand, there are many websites devoted to presentation design articles and tips. Gary Reynolds offers this advice, "You can take your own high-quality photographs with your digital camera, purchase professional stock photography, or use the plethora of high-quality images available online."
According to OSHA, you must "account for production time in your planning and selection process." Your level of familiarity with creating presentations and designs will determine how much time you have to expend on this project, and if you're a beginner, it will take considerably longer. On the other hand, if you don't have a rapidly approaching deadline or other projects or tasks that require immediate attention, time should not be a determining factor.
If there is no one in your department who creates presentations and designs, you may have to pay a third party to perform this service. Depending on their rates and the length and complexity of your project, this can be quite costly. In addition, if there are mistakes on your original information, the vendor may charge you an additional fee for corrections. On the other hand, if you already own or have access to presentation software, you can avoid these expenses.
If you encounter problems while you're creating the presentation, you will be responsible for troubleshooting. Depending on your schedule, this may cost you valuable time, and in the end, you may not be able to solve the problems alone. On the other hand, since presentations are so popular there's a high probability that you have a coworker or friend who can assist you. In addition, most presentation software includes troubleshooting tabs, online manuals, and tech support via phone or email.
