DevOps Braga #22 & DevOps Lisbon [ONLINE]: Mary Poppendieck

Xullo 13 @ 7:00 PM - 9:00 PM

De balde

Yet another very special guest. Mary Poppendieck has been at the forefront of our industry throughout her career. She was one of the first practitioners to bring Lean ideas into software development, well before they were popularized by DevOps and Agile in the last couple of decades.

Mary will share her experience and major themes throughout six decades of software engineering, from mainframes to DevOps!

Don’t miss this chance to hear from a luminary in our field!

Link to Zoom (videoconference) will be visible on this page on the right side (under “Online event”) once you are logged in and registered for this meetup.

The event starts at 19:00 sharp, please try to connect on time!


TALK: Six Decades of Software Engineering
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.


Remember our guidelines of engagement in the video call, to make sure things run as smoothly as possible:

1. When you join, you will be kept muted to avoid noise

2. We ask you to rename yourself to include your name and city/location

3. Turn on your webcam if you don’t mind, so we can recognize each other’s faces and make this more in-person like 🙂

4. After each presentation, there will be a Q&A round

5. If you have a question, “Raise hand” to let us know OR write it in the chat

5.1. If you “raise hand”, we will call your name and unmute you so you can ask the question

5.2. If you write the question in the chat, we will read it out loud

5.3 Try to limit questions to 1 per talk

6. Feel free to use the chat for discussions with other participants

7. We will keep the call open for 10/15m after the talks for further discussion, virtual networking if you like 🙂


IMPORTANT NOTICE: The talks will be recorded and published in the DevOps Lisbon YouTube channel. By signing up for this event you explicitly agree that your image might appear in the video recordings. Nevertheless, you can always get in touch with the organisation ( to have it removed.
