As a professional practice, we do not recommend native PPT animations in a typical business presentation. Animation is only useful if it’s adding any value to the presentation; otherwise it may actually distract the audience from core message. Our design team would focus their efforts in making an impact through design and not animation. However, if you insist and feel it may add value to your presentation, we will add the basic (non-fancy) slide transitions and animation effects once the PPT is finalized by you.
There are some specific cases like process flows, diagram explainers etc where-in animation may actually add lot value. In such cases, we may make an exception. If you need animation only for cosmetic reasons i.e. to make it look very dynamic, we recommend different presentation formats like animated video based presentations.
