Platform as a Product

There’s a lot of information (and misinformation) on the concept of “Platform as a Product” in respect to current thinking in DevOps and organisational dynamics, and this is where I’m gathering my thoughts on that.

The core premise of “Platform as a Product” is to make explicit the need for a platform (low variability) to exist as a separate system from the customer-facing products (high variability), and requires a long-lived platform team, practices, and budget to support it. Platform as a Product is not a perfect approach, and it certainly isn’t the “only” way to utilise the power of cloud platforms for development teams, but this approach has been shown to work for teams and organisations at various stages of maturity.

Evan Botcher describes a platform as follows:

A digital platform is a foundation of self-service APIs, tools, services, knowledge and support which are arranged as a compelling internal product. Autonomous delivery teams can make use of the platform to deliver product features at a higher pace, with reduced co-ordination.

From “What I Talk About When I Talk About Platforms” by Martin Fowler

In this article, I’ll try to outline my thinking in the rationale and benefits of adopting a Platform as a Product approach to technology and platform teams themselves.

Types of work:

When we’re building software, we’re not manufacturing goods: i.e. we’re not producing the same thing over and over and trying to minimise variation. Neither are we building a single large deliverable, like a bridge or a custom car. We’re building a long-lived evolving product.

types of work

And that’s important to remember: products evolve over time, and there are elements of the product that we want to stay the same and benefit from stability, reliability and security as a result. But there are elements of the product that we want to change frequently, such as features, UX, and integrations. A platform as a product approach allows us to differentiate between the different needs and requirements of different parts of the system, and decouple those elements that need to change fast and often, from those that need to provide stability and reliability, and change less often. Different parts of the system demonstrate different levels of variability, and thats where platforms come in.

Cost of Delay

Part of the reason we want to be able to move quickly and introduce new features and changes is to reduce our Cost Of Delay – see the charts below:

cost of delayThe chart above shows the cost of delay for a simple product: the sooner you get the product to market, the sooner, you begin to realise value.

cost of delay - opportunityThe chart here shows what happens if a competitor releases before you do. Not only do you miss out on the revenue due to the delay, but your competitor has grabbed the customers that you would have acquired if you’d released sooner. And because you can’t now get those customers, the loss is far greater: this is a case of missing the market window. So, let’s use platform as a product approach to reduce our cost of delay.

Software Delivery Performance

Accelerate Nicole Forsgren

Nicole Forsgren, in her book, Accelerate, describes four key DevOps delivery metrics :

  • Lead time to change
  • Deployment frequency
  • Mean time to restore (MTTR)
  • Change failure rate

These metrics all describe capabilities that ultimately reduce your cost of delay, as well as customer satisfaction. So, let’s try to improve these metrics by implementing platform as a product approaches.

(Note: we shouldn’t be trying to reduce change failure rate or MTTR to zero – for all these metrics, we should be optimising them rather than striving to get them to zero or maximise deployment frequency.)

Handoffs and Flow

Handoffs reduce flow. Just ask these baton runners. Even with many hours of practice, a handoff can still result in failure and an impediment to speed. So, let’s reduce handoffs between team members by using a platform as a product so that developers can use and deploy systems on-demand.

Not only do handoffs reduce flow, but if someone is busy, they can’t even accept the work you’re trying to give them. This is the only chart in the Phoenix project and describes the exponential impact on wait time as utilisation increases above ~80%. So, let’s reduce utilisation to acceptable levels at the same time as reducing handoffs (or eliminating them completely) by adopting the platform as a product approach and saving developers time that might be spent on maintenance and management of the underlying infrastructure.

Team Size

The two diagrams above show us that team sizes shouldn’t exceed certain numbers. Communication complexity shows us that above 8-9 team members (such as SLAM teams), communication becomes a blocker via exponentially increasing complexity. Dunbar’s theories also suggest (possibly as a result of communication complexity) that teams should remain below 15 people. So, let’s keep team sizes appropriately small by having a separate platform product team and development product teams.

Developer Cognitive Load

From Fraser, K. et al. (2018) “Cognitive Load Theory for debriefing simulations: implications for faculty development”, Advances in Simulation, 3(1). doi: 10.1186/s41077-018-0086-1.

Cognitive load is critical in software development.

Intrinsic cognition is all the stuff you already know, such as how to make a decent cup of tea. Where the teabags are, how to operate the kettle, how much milk to put in, etc.

Extraneous cognition is all the external stuff that you need to find out or understand, such as where someone left the teabags because you can’t find them. It also includes “noise” such as distractions, how to operate unfamiliar equipment, or how to comply with regulatory requirements.

Germane cognition is active learning and problem solving. That’s the stuff of real value – such as comparing Tetley tea to Yorkshire Tea in a taste test to find out which is better.*  It’s also the process by which learning is transferred from short-term to long-term memory. It’s only through Germane cognition that we actually achieve anything or provide real value.

So, let’s minimise our extraneous cognitive load for developers and reduce the need for intrinsic cognitive load, so that the maximum effort can be put into the germane problem solving. The platform product does this by improving the developer experience (DevEx) and making it easier for developers to do what they need to do without referring to documentation or asking someone how to do something.

Thinnest Viable Platform

The platform itself needs only be as big as necessary to reduce the cognitive load of developers: so it may be sufficient for the platform to be a simple one-page repo describing how to deploy to AWS, or the platform could be a fully contained, multi-region, multi-cloud, self healing pipeline and platform. Matthew Skelton refers to this approach as the “Thinnest Viable Platform”.

Evidence for Platform As A Product successplatform as a product - devops reports

The State of DevOps reports from 2020 and 2021 provide strong evidence that adopting a platform as a product approach, using internal platform teams, improves software delivery performance, via many of the mechanisms described above.

Platform Teams

Matthew Skelton and Manuel Pais, in their book Team Topologies, describe four team types that enable fast flow in software development (and in other domains too). We won’t go into all four types and the three interaction modes here – there’s a ton of great information on the Team Topologies website. The platform team is essentially just like any other stream-aligned team, except their product is the platform itself, and their customers are the developers who use it.

Personal note: I’m uncomfortable with the premise of teams in an organisation categorising other teams as customers or suppliers because it can subordinate one team to another. I worry that language could lead us back to the bad old days of Ops teams being subordinate to Dev teams and a reversion back to silos. Instead, I suggest that you can use this concept to determine the boundaries of teams and create “Team APIs” and social contracts to surface and make explicit how teams communicate with each other. 

Platform As A Product

I would strongly advise also looking at internalising service design capabilities and expertise to help teams design and build the platform. The platform as a product approach is fundamentally a practice to enable improved efficiency, improved product quality and reliability and faster speed to market, via reducing cognitive load for developers, faster flow of work, reduced handoffs, and enabling developers to focus on delivering value.


Criticisms of the Platform as a Product Approach

This approach certainly isn’t perfect. As with any framework or defined practice, it should be considered as a stage of a journey, and it may well be the case that very mature and highly capable technology delivery teams don’t require this approach, and can adopt a rather more polycentric, shared commons approach that doesn’t require the platform to have a dedicated team, but distributes ownership across multiple teams. Check out Jabe Bloom on the Boundaryless podcast if you’re interested further – Platforming inside and between organizations: differentiation, scale, and scope.

However, I believe that most teams are not yet at that stage of maturity or capability, and it may take a long time to get there, so I feel that the Platform as a Product approach is a valid and effective path to high performance and effective delivery.

Hybridisation and the heterosis of hybrid work.

heterosis in wheat

Hybrid work is upon us. 

Hybridisation in biological systems often creates a phenomena known as heterosis (also known as “hybrid vigour”): where the combining of two distinct varieties or genotypes results in a far stronger, more vigorous offspring, even though the resulting hybrid is usually sterile. Many commercial crop varieties are based on this principle, and the mule is a good example too, as the offspring of a male donkey and a female horse.

I’ve also been thinking about “hybrid” ways of working, and whether this kind of hybridisation also results in stronger and “better” outcomes. It’s much, much harder to create successful hybrid working systems and environments, but if we get it right, it allows us to exploit the benefits of both: the time saving efficiencies and comfort of remote and home working, combined with the power of high-bandwidth, in-person collaboration. But done badly, it results in the exclusion of individuals dialling in remotely to an in-person meeting, unpredictable travel patterns and lack of habit and ritual formation that’s so important to a high performing team.

If we’re going to make hybrid work, work for us, we need to be very intentional in designing the systems, processes, environments and practices that we use. And we must adopt an experimental approach, constantly evaluating and re-evaluating our decisions in order to keep, improve, or discard them in response to feedback. 

Hybridisation of work can make us stronger, but only if we’re intentional and humble in our approach. If we are not, we risk degrading our outcomes as well as burning out our people.

Maybe the sterility of the outcome is where the analogy ends however!
