Scrum is a Lean approach to Software development.

The term itself (“Scrum”) was introduced by Takeuchi and Nonaka (1986). The study was published in Harvard Business Review in 1986.

Scrum for software development was introduced in 1993 by Jeff Sutherland at Easel Corporation using the study by Takeuchi and Nonaka (1986) as a basis for by adopting their analogy as the name of the process as a whole for software development. The other name linked to Scrum is of course Ken Schwaber who formalized the process for the worldwide software industry in the first published paper on Scrum at OOPSLA (Schwaber, 1997).

There is one thing in common with a lot of software development companies, or companies that have a software development unit. That’s the system labeled with the monstrous name “Legacy”.

So what’s in it, really?

Is your software change tolerant? Is your software easy to adapt to changes proposed by the business, or the tech department itself? Are you software’s modules independent and enable change? Does your software enable quick releases?

If you were nodding your head negatively about all of the above mentioned questions, then… I am really sorry but you’re dealing with Legacy software.
