Not so long ago, I impressed the daylights out of a friend, by showing him his face on my PC's screen. As I tapped away at the minus key, the picture slowly zoomed-out, revealing that it was a picture of the two of us, and it soon became clear where the picture was taken. As I continued to zoom out, more details came into view; the picture was actually a small part of a scanned photograph of the two of us sitting by my desk, watching the monitor. The photo was merely lying on the desk when the high-resolution picture was taken.

Aside from the fact that even just viewing this high-resolution picture took up obscene amounts of disk space and memory, and slowed down my PC to the speed of a Sinclair ZX-81, the story also serves as a fairly long-winded analogy to an important business concept. We constantly lose track of the big-picture; we forget what we're trying to achieve, and get sidelined dealing with email enquiries, financial issues, bug-fixes, submitting our site to the search engines and other day to day tasks. All part of running a small web-based business. The bigger companies have staff to deal with the correspondence, answer the phone, market their products and spend day or weeks on getting their new logo just right. We do not.

But there's a serious risk to this; not only is it incredibly easy to lose track of where you are and what you're doing, chances are you won't even see the threats and opportunities that may be passing you by without you even realising.

Which is why I love the SWOT analysis - one of the few genuinely useful tools that I picked up during my years at the Leeds Business School. SWOT stands for Strengths, Opportunities, Weaknesses and Threats - and offers a fast, simple and powerful tool for internal and external appraisal.

The idea that you as a company should play to your strengths and improve on your weaknesses is a simple and obvious one, but first of all you need to identify them. Ten minutes is all you need to give this a go
