It occurred to me today that I can roughly track my career progression using the components of the extended Microsoft Office suite. That is, you can tell where I was based on which Microsoft software product I was using the most at that time.
Word & Access
When I first started my career, for example, the two components I used the most were Access to Word. This was when most of my work was technical in nature and I was the guy who built things - like Access databases - from the ground up. I then documented them and wrote manuals about them in Word.
When I moved into more of a senior developer or project lead role my focus shifted from Access to Project. This is because I wasn't building things any more, I was tracking the progress of my team and the products we were building.
My next step up was into an analyst role and in this I used a lot of Excel. I used that for both analysis (technical, business, and financial) and reporting (productivity, web traffic stats, budgets, and so on).
Later, after my MBA, I did more of the same but this time I was also a big user of Outlook. That was my step up from the start-up and nonprofit world into the corporate and enterprise world.
Now what I use the most is PowerPoint. I still use all the other tools, of course - though not Access and not too much Project these days - but I've gone from being purely a professional to being a manager and an ideas person, hence the need for good presentations.
Come to think of it, I can also track my career progression just by talking about what I used Word for. That is, I went from using it to document and write manuals to writing proposals and reports to writing policies and strategies.
Neat, huh? :)
