Nordstrom Case Study from The DevOps Handbook through the Lens of Slowify, Simplify, Amplify (Part 1)
The goal of science is to explain the most amount of observable phenomena with the fewest number of principles, confirm deeply held intuitions, and reveal surprising insights. This is known as the principle of parsimony .
With Wiring the Winning Organizations, we present a very simple and parsimonious theory of performance, based on the three mechanisms of slowification, simplification, and amplification. I’ve been continually amazed at how every transformation can be described using these three mechanism:
Over the next several months, I’ll be showing examples of these mechanism at work. I’ll be picking some of my favorite case studies from The DevOps Handbook and describing them through the lens of slowification, simplification, and amplification.
Below is an abbreviated version of the Nordstrom case study from The DevOps Handbook, 2nd Edition, followed by specific examples of the three mechanisms from Wiring the Winning Organization .
(We used GPT-4 to halve the word count down the original 1000-word case study. Astonishingly, the examples of the three mechanisms were also generated by GPT-4. To me, the fact that GPT-4 can do this so well is strong evidence of the correctness and expressiveness of our model. In other words, we can explain so many observable phenomena, using fewer words!)
Abridged Nordstrom Case Study: Digital Transformation?
Let us examine how the Nordstrom team started their DevOps transformation initiative in 2013, which Courtney Kissler Hawkins , their VP of E-Commerce and Store Technologies, described at the DevOps Enterprise Summit in 2014 and 2015.
Founded in 1901, Nordstrom is a leading fashion retailer focused on delivering the best possible shopping experience to its customers. In 2015, Nordstrom had annual revenue of $13.5 billion.
The stage for Nordstrom’s DevOps journey was likely set in 2011 during one of their annual board of directors meetings... The strategic topics discussed were the need for online revenue growth. They studied the plight of Blockbuster, Borders, and Barnes & Noble... These organizations were clearly at risk of losing their position in the marketplace or even going out of business entirely...
In 2011, the Nordstrom technology organization was very much optimized for cost—It had outsourced many of their technology functions, and had an annual planning cycle with large batch, “waterfall” software releases...
Kissler and the Nordstrom technology management team had to decide where to start their initial transformation efforts... They focused on three areas: the customer mobile application, their in-store restaurant systems, and their digital properties...
The Nordstrom mobile application had experienced an inauspicious start...any fixes to the application would have to wait months to reach the customer.
Their first goal was to enable faster or on-demand releases... They created a product team that was solely dedicated to supporting the mobile application… They had the goal of enabling the mobile application team to be able to independently implement, test, and deliver value to customers...
Furthermore, the mobile application team moved from planning once per year to a continuous planning process... Over the following year, they eliminated testing as a separate phase of work; instead, they integrated it into everyone’s daily work... They doubled the features being delivered per month and halved the number of defects...
Their second area of focus was the systems supporting their in-store Café Bistro restaurants... In 2013, Nordstrom had completed eleven “restaurant re-concepts”...
As Kissler stated, “One of our business leaders suggested that we triple our team size to handle these new demands, but I proposed that we had to stop throwing more bodies at the problem and instead improve the way we worked.”... They were able to reduce code deployment lead times by 60% and reduce the number of production incidents 60-90%.
These successes gave the teams confidence that DevOps principles and practices were applicable to a wide variety of value streams.?
In 2015, Kissler said that in order for the selling or customer-facing technology organization to enable the business to meet their goals, “we needed to increase productivity in all our technology value streams, not just in a few...”
She continued, “This is an audacious challenge... Our first target condition requires us to help all our teams measure, make [the work] visible, and perform experiments to start reducing their process times, iteration by iteration.”... From a high-level perspective, we believe that techniques such as value stream mapping, reducing our batch sizes toward single-piece flow, as well as using continuous delivery and microservices will get us to our desired state...
Nordstrom’s Transformation Viewed through the Three Mechanisms of Wiring the Winning Organization
Now that we have reviewed this case study from The DevOps Handbook, 2nd edition, let’s see how Nordstrom moved from the danger zone to the winning zone using the three mechanisms of slowification, simplification, and amplification introduced in Wiring the Winning Organization.?
Slowification
Nordstrom shifted from a fast-paced, cost-optimized approach to a more deliberate focus on speed and agility. This shift was triggered by the need for online revenue growth and the realization that traditional retail models were at risk.
They decided to focus on specific areas of the business to experiment and learn, rather than causing upheaval in the whole system. This allowed for more deliberate planning and practice. (In other words, they created a model line—a small but coherent unit in which they could more safely experiment and change.)
They targeted the customer mobile application, in-store restaurant systems, and digital properties for initial transformation efforts.
Simplification
Nordstrom simplified their approach by focusing on specific areas of the business for their initial transformation efforts. This made the complex task of transformation more manageable.
They created a dedicated product team for the mobile application, enabling the team to independently implement, test, and deliver value to the customer. This reduced the need for coordination with other teams.
They moved from an annual planning cycle to a continuous planning process, simplifying the prioritization of work based on customer needs.
Amplification
Nordstrom amplified the issues with their mobile application by acknowledging the negative reviews and the inflexible structure that allowed only biannual updates.
They identified the need for faster releases and quicker responses to customer feedback, which highlighted the issues with their existing processes.
Their focus on reducing code deployment lead times and reducing the number of production incidents in their in-store Café Bistro restaurants also amplified the issues in these areas and led to significant improvements.

1 年What's with the ... between sentences in the (abridged) Nordstrom case study paragraphs? It looks odd when every other paragraph has regular punctuation.
