Our 4th Open Space discussion challenged people to identify the things that they don’t like about the Continuous Delivery book: things that don’t work in practice, things that are plain wrong, etc. – a slightly cheeky session!
tl;dr: Jez Humble and Dave Farley – authors of Continuous Delivery – did not get anything wrong in their book but they “did not say enough” about the culture/people aspect of Continuous Delivery. People and culture are tricky – who knew?! 🙂

Applying the principles and practices of Continuous Delivery for new software is fairly straightforward (at least, until you deal with data and databases). However, existing “legacy” systems that were built without many automated tests and without much concern for repeatable deployments of discrete functionality pose a challenge for moving to Continuous Delivery.

Continuous Delivery for web applications is (in 2017) largely a solved problem but where data and databases are concerned, Continuous Delivery becomes more difficult (I have written quite a bit about Continuous Delivery and Databases on the Redgate Simple Talk website – worth a read if you’re interested). In the meetup, we explored some of these challenges and some solutions to Continuous Delivery for databases. (Thanks to Alex Yates of DLM Consultants for his expertise in facilitating the discussion!)

How do we continuously address security concerns with modern software development? That was one of the questions we discussed and tried to answer at LondonCD meetup group on 12 June 2017. “The yearly PEN test is dead!”, said one person, meaning that reliance on an infrequent, specialist test to address all security problems is simply not good enough any more.
I was recently asked to answer some questions about Continuous Delivery for someone’s undergraduate university research. The questions were interesting, so here are my answers 🙂
- What do you feel are the benefits of adopting Continuous Delivery?
- How do you feel adopting Continuous Delivery has affected your development cycle?
- Do you think Continuous Delivery is an important approach for a company to pick up, If so Why?
- How do you think Agile compares to more traditional models like Waterfall?
- What is the biggest change you’ve noticed since adopting Agile?
- What do you foresee in the future for these models in the industry?
1. What do you feel are the benefits of adopting Continuous Delivery?
The benefits of Continuous Delivery are huge:
- Greater focus on finishing and shipping.
- Increased awareness of need for setting up the work to enable feedback and learning.
- Sense of ‘flow’ within teams.
- Decisions made using actual data rather than opinions alone.
- Higher quality software.
- More joy in work.
(Can I stop yet?)
2. How do you feel adopting Continuous Delivery has affected your development cycle?
(Answering on behalf of our clients) Continuous Delivery has helped us to increase the ownership over software and focus on the value-add things that our organisation produces, rather than ceremonies around testing and releasing.
3. Do you think Continuous Delivery is an important approach for a company to pick up, If so Why?
Yes: adopting CD properly can be truly transformative for the organisation as a whole. IT becomes a means to receive rapid feedback on product/marketing/service offerings, allowing the business to invest more wisely and do more with less risk and lower costs.
4. How do you think Agile compares to more traditional models like Waterfall?
Agile is woefully misunderstood (as was Waterfall) so in that regard, they are similar (!). Truly agile organisations are rare because agility challenges entrenched, comfortable positions within an organisation. Agile done well really makes the nature of an organisation transparent.
5. What is the biggest change you’ve noticed since adopting Agile?
(Answering for our clients) We’re able to improve the software delivery part of the process, but this has highlighted the lack of clarity and vision in the Business.
6. What do you foresee in the future for these models in the industry?
We’re starting to see a backlash against Agile and DevOps already, because people misunderstand or misrepresent what’s going on. Things like SAFe seem to be rebranded PRINCE2 which is a shame. Essentially, many organisations are going to fail because their management does not see the need to change.
At Skelton Thatcher Consulting we have put together a handy Continuous Delivery checklist template (on Trello) to help you assess the things you need to address within your organisation:
In an environment of rapidly-changing technology and approaches, an internal tech conference can be a powerful and effective way of spreading new ideas and practices and sharing learning & experience. Having organised and run several internal tech conferences (at different organisations), Victoria Morgan-Smith and I decided to write about our experiences in an article for InfoQ: Internal Tech Conferences – How and Why. We also interviewed several other people from various organisations who have also run internal tech conferences in order to give a broader perspective.
Our aim was to inspire and enable other people to develop and run internal tech conferences in their own organisations, building on the experiences of the teams and organisations in the article.
In this article we draw on our personal experience of running internal tech events at companies we’ve worked with, along with reflections and advice from people at Paddy Power Betfair, Callcredit Information Group, ING and others. You’ll find further reading & listening material at the end of the article – there is so much inspirational work happening in so many organisations.
Key points from the article are:
- Software engineering today is as much about people as the technology itself: an internal tech conference can give a huge boost to your organisation’s social capital – that currency by which relationships flourish.
- The format you choose for your internal tech conference depends on what you want to achieve from it: it can be “by the people for the people”, or a showcase to celebrate achievement. You can keep the audience or speakers to just a single department, or invite other divisions, or even invite external speakers and/or audience.
- Making the event a success takes effort: choose your speakers well, and mentor themas they prepare their talks. Work on the logistics – it’s the little things that count.
- Remember to have fun: ‘death by PowerPoint’ will mean people remember the event for the wrong reasons!
- Follow through: for a lasting impact, keep sight of the outcomes you seek and be ready to work with others to keep the momentum going.
We hope that the article is useful for people thinking of running or improving their own internal tech conferences!
Thanks to everyone involved: people we interviewed, the amazing InfoQ team, and to my co-author Victoria Morgan-Smith.
Back in 2010 when Jez Humble and Dave Farley wrote their ground-breaking book Continuous Delivery, the Windows and .NET platforms lagged behind the Linux/Mac world in terms of automation capability. That is no longer the case – every core feature in Windows and .NET now has a PowerShell API and all the core tooling needed for Continuous Delivery – package management, artifact repositories, build servers, deployment pipelines tools, infrastructure automation, monitoring,and logging – are all now available natively on Windows/.NET.
Chris O’Dell (@ChrisAnnODell) and I decided we should explain how to make Continuous Delivery work with Windows and .NET, and thanks to the great editorial team at O’Reilly, we’ve published a short eBook:
The dedicated book website is at CDwithWindows.net and O’Reilly have published the first chapter of the book online as an article: Introduction to Continuous Delivery with Windows. We’d love your feedback: firstname.lastname@example.org
UPDATE: we’ll be at both PIPELINE Conference (March 23 2016) and WinOps Conference (May 24 2016) with printed copies of the book.
Note: we began writing the book in August 2015, and it’s astonishing (and exciting!) how much has changed in the 8 months since then, with Windows Nano, Azure and Windows support for Docker and containers, .NET Core, SQL Server on Linux, and even SSH for Windows. These and more recent developments do not feature in the book – perhaps we’ll do an updated version soon.
