If you complete tender responses from to time you may recognise this feeling.
You might have previously created, in the heat of the moment, some material for a tender, submitted it and then forgotten about it. You are now doing another tender. You are pretty sure that the previously written material would be really useful, but you can’t find it, at least, not without wading through many files and much material.
My tip is simple. When you have completed a tender response take five minutes to bookmark the material that might be useful in future. This is the time to do it, when it is fresh in your mind. Create a hyperlink to this from a central index index for all such material, and in future you will not only be able to go straight to the right file, but straight to the right place as well.
All that earlier creativity won’t be wasted!
