"I really like the way you can access your work items from within Outlook. I like the way you can bring up the full work item forms, make edits, and save immediately to TFS. It was great to create new meeting requests or mail messages from the work items."

Lori Lamkin
Product Unit Manager for Team Foundation Server at Microsoft

"These types of products are important to the industry."

Joel Semeniuk
CEO and co-founder of ImagiNET Resources Corp.

"I know of a good number of companies that will love having something like this - getting their timesheet management into TFS (so it can be reported on, especially) will make life a lot easier for them."

James Manning
Software Design Engineer for Visual Studio project at Microsoft

"I like the idea of being able to link work items to e-mails and meetings. I also like that it provides non-technical information workers the option of working with TFS in a more familiar environment. Congratulations to TeamExpand on the release!"

Jason Barile
Principal Test Manager for Visual Studio Team Foundation Server at Microsoft

"TX Chrono, by TeamExpand, allows users to easily track how they are spending their time, store that information in TFS, and make it available for reporting in the warehouse."

Brian Harry

The difference between SDLC and ALM?

January 22nd, 2008

Just thought of the difference between Software Development Life Cycle and Application Lifecycle Management…as similar as they sound, and as different as they are conceptually, I often find people confusing the two. It’s probably easier to see the difference if you think of SDLC as one of the ALM stages or as a part of ALM.

The notion of ALM presupposes something more than solely developing a software application from the bottom up and getting it to work, it’s much more than that. ALM starts a lot earlier than development and ends much after the application is actually developed and ready to be used. ALM starts when the idea to create a software solution to a certain problem is born, in business. It starts as a new challenge, maybe a need, or that very first vague and blurry vision. After it’s thoroughly discussed and formulated, the idea gets into the SDLC stage of ALM, where developers, coders, testers, project managers, etc. get to work on it.

But that is not at all the final stage. After your solution is ready, it needs to actually be “up and solving” and executing the tasks it was designed for. The application here needs to be promoted, marketed, sold and implemented. This stage may take years, or, in the worst case, less. =)

Hope this clears things out a bit.
