After publishing Excel and Word versions, today the SWOT Analysis Template for Microsoft PowerPoint is available for download.
Why copy and paste your already completed swot form in other formats only to paste it into a PowerPoint presentation when you can just complete it in PowerPoint from the start? Of course, this will depend on how you intend to use the template? If if its for strictly use in a lean six sigma effort, Excel would be fine; if you intend to use it for academic purposes, go for Word. You can find the SWOT template for Microsoft Excel here and the Microsoft Word version here.
