Six Decades of Software Engineering – Mary Poppendieck (46m talk + 36m Q&A) [2020.07 DevOps Lisbon]
Speaker: Mary Poppendieck
Mainframes were born in the 1960’s, along with the earliest electronic telephone switching systems. Minicomputers arrived in the 70’s, and so did ARPANET. PC’s came of age the 80’s, as well as languages that were so simple we figured anyone could use them. This led to many a disaster – from bloated, unmaintainable corporate systems to medical device failures. And so the 90’s became the decade of heavy process; but it was also the decade that open source software came of age.
Then along came Y2K, which brought us the Internet companies, Agile software development, and the decade of teams. Try as they might to be autonomous, the teams inherited monolithic databases and deep dependencies. To solve these problems, the 2010’s became a decade devoted to flow (DevOps) and architecture (microservices). Now in the 2020’s our world has changed dramatically, faster than anyone could have imagined, and we have to learn how to change our software just as fast.
From my first ‘Hello World’ in 1961, I’ve watched software migrate from automating business processes, to a product in its own right, to a fundamental element of our infrastructure. This talk will cover some of the early principles behind great software engineering that are as true today as they were a half-century ago; and it will cover a few mistakes we made that we do not need to repeat.
Mary Poppendieck has been in the Information Technology industry for over fifty years. She has managed software development, supply chain management, manufacturing operations, and new product development. She spearheaded the implementation of an early Just-in-Time production system and led new product development teams that commercialized products ranging from digital controllers to 3M Light Fiber™.
A popular writer and speaker, Poppendieck is the coauthor of four books: Lean Software Development, 2003. Implementing Lean Software Development, 2006. Leading Lean Software Development, 2009, and Lean Mindset, 2013.
