I’ve said elsewhere that I’m wary of too much emphasis on tools – one big risk being that learn a good tool and there’s a temptation to look for problems needing it as a solution and it’s easy to end up twisting the problem to fit the tool. A good professional has a broad range of tools at his/her disposal and, whilst not necessarily an expert in every one of them, understands when to use them. To this end, I’m including a number of items to describe some of the tools available.
Some may be known by other names and described differently elsewhere but I’m not going to go into great depth on them – these pages are meant to serve as an introduction and overview. There are many good books and online locations to pursue them in detail – probably for when you first need to use a new tool in anger.
