Flash is a great multimedia tool. Here are some of the advantages:

• Fairly easy to create
• Files are small
• Great for the Web
• Can be used in PowerPoint (walk-in, intro, breaks, closing)
• Can be used on a laptop (as a product demo, ROI calculator, a full presentation, to name a few)
• Far cheaper than video
• More powerful, natural animation than presentation software can provide

A few disadvantages:

• Not easily revised, unlike PowerPoint
• Flash .exe files can’t be easily emailed. All firewalls strip .exe file from the email since they’re one of the top ways to spread viruses.
• Heavily photographic pieces can be problematic
• Can’t be created by a non-pro
• Much longer timeline due to multiple steps – script, theme, photos, music, voice over, storyboard, first draft, approvals, final drafts and revisions
• Can be expensive
