The success of an inside platform is outlined by what number of groups undertake it. Because of this a
platform crew’s success hangs on their means to collaborate with different groups, and particularly to get
code modifications into these groups’ codebases.
On this article we’ll take a look at the completely different
collaboration phases that platform groups are likely to function in when working with different groups, and
discover what groups ought to do to make sure success in every of those phases.
Particularly, the three platform collaboration phases we’ll be are
platform migration, platform consumption, and platform
evolution. I’ll describe what’s completely different in every of those phases,
focus on some working fashions that platform groups and product supply groups
(the platform’s prospects)
can undertake when working collectively in every part, and take a look at what cross-team collaboration patterns work
finest in every part.
When contemplating how software program groups collaborate, my go-to useful resource is the fantastic
Group Topologies guide. In chapter 7 the authors
outline three Group Interplay Modes: collaboration, X-as-a-service, and facilitating.
There may be, unsurprisingly, some overlap between the fashions I’ll current on this article
and people three Group Topology modes, and I will level these out alongside the way in which. I will additionally
refer again to a number of the common knowledge from Group Topologies within the conclusion to this
article – it truly is an especially precious useful resource when enthusiastic about how groups work
collectively.
Platform Supply groups vs. Product Supply groups
Earlier than we dive in, let’s get clear on what distinguishes a platform crew
from different varieties of engineering crew. On this dialogue I’ll usually consult with
product supply groups and platform supply groups.
A product supply crew builds options for an organization’s prospects – the
finish customers of the product they’re constructing are the corporate’s prospects.
I’ve additionally seen some of these engineering crew known as a “characteristic
crew”, a “product crew” or a “vertical crew”. On this article I will use
“product crew” as a shorthand for product supply crew.
In distinction, a platform supply crew builds merchandise for different groups contained in the
firm – the top customers of the platform crew’s product are different groups
inside the firm. I will be utilizing “platform crew” as a short-hand for “platform supply crew”.
Within the language of Group Topologies, a product supply crew would sometimes be characterised
as a Stream Aligned crew. Whereas the Group Topologies authors initially outlined
Platform Group as a definite topology, they’ve subsequently come to see “platform”
as a broader idea, reasonably than a definite method of working – one thing I very a lot agree with. In
my expertise in the case of Group Topologies terminology a very good platform tends to function as both
a Stream Aligned crew – with their platform being their worth stream – or as an Enabling crew, serving to
different groups to succeed with their platform. Actually, in most of the cross-team collaboration patterns we’ll
be on this article the platform crew is performing in that Enabling mode.
“Platform” > Inner Developer Platform
There’s numerous buzz in the intervening time round Platform Engineering, primarily
centered on Inner Developer Platforms (IDPs). I wish to make it clear that
the dialogue of “platforms” right here is considerably broader; it encompasses different inside merchandise
resembling a knowledge platform, a front-end design system, or an experimentation platform.
Actually, whereas we might be primarily involved with technical platforms, numerous the concepts
offered right here additionally apply to inside merchandise that present shared enterprise capabilities – a cash motion
service at a fintech firm, or a product catalog service at an e-comm
firm. The unifying attribute is that platforms are inside merchandise utilized by different groups inside a company.
Thus, platform groups are constructing merchandise whose prospects are different groups inside their firm.

Phases of platform adoption
Okay, again to the several types of cross-team work. We will look
at three eventualities that require collaboration between platform groups
and product supply groups: platform migrations, platform consumption, and
platform evolution.
As we take a look at these three phases, it is vital to notice two particular
traits: which crew is driving the work, and which crew owns
the codebase the place the work will occur. The solutions to these two
questions significantly have an effect on which collaboration patterns make sense in every
situation.
Platform Migrations
We’ll begin by platform migrations. Migrations contain
modifications to product groups’ codebases in an effort to swap over to some new
platform functionality.
We see that in these conditions it is a platform crew that is driving the
modifications, however the possession of the codebase that wants altering is sits with a special crew – a product crew.
Therefore the necessity for cross-team collaboration.
Examples of migration work
What varieties of modifications are we speaking about? One comparatively easy
migration could be a model upgrade- upgrading a shared element
library, or upgrading a service’s underlying language runtime.
A typical, bigger migration could be changing direct integration of
a third social gathering system with some inside wrapper – for instance, shifting
logging, analytics, or observability instrumentation over to utilizing a
shared inside library maintained by a platform crew, or changing
direct integration with a fee processor with integration through an
inside gateway service of some variety.
One other kind of migration is perhaps changing an present integration right into a deprecated
inside service with an integration into it is substitute – maybe shifting from an outdated Person
service to a brand new Account Profile service, or migrating utilization of a
credit-puller and credit-reporting service to a brand new consolidated
credit-agency-gateway service.
A last instance could be an infrastructure-level re-platforming –
dockerizing a service owned by a product crew, introducing a service
mesh, switching a service’s database from MySQL to Postgres, that kind
of factor.
Word that with platform migrations the product crew is usually not particularly motivated
to make these modifications. Generally they’re, if the brand new platform goes to supply some
significantly thrilling new capabilities, however usually they’re being requested to make this shift
as a part of a broader architectural initiative with out really getting an enormous quantity of worth
themselves.
Collaboration Patterns
Let’s take a look at what cross-team
collaboration patterns would work for platform migration
work.
Farm out the work
The platform crew might File a Ticket within the
product groups’ backlogs, asking them
to make the required modifications themselves.
This strategy has some benefits. It’s scalable – the
implementation work could be farmed out to all of the product groups whose
codebases want work. It’s additionally trackable and simple to handle – usually
the ticket submitting could be carried out by a program supervisor or different mission
administration kind.
Nevertheless, there are additionally some drawbacks. It’s actually gradual –
there might be lengthy lead instances earlier than some product groups get round
to even beginning the work. Additionally, it requires prioritization
arm-wrestling – the groups being requested to do that work usually don’t
obtain tangible advantages, so it’s pure that
they’re included to de-prioritize this work over different duties that
are extra pressing or impactful.
Platform crew does the work
The platform crew would possibly choose to make modifications to the product crew’s
codebases themselves, utilizing three related however distinct patterns –
Tour of Obligation, Trusted Outsider, or Inner Open Supply.
With Tour of Obligation, an engineer from the
platform crew would “embed” with the product crew and do the work
from there.
With Trusted Outsider and Inner Open Supply the product crew would settle for pull
requests to their codebase from an engineer within the platform crew.
The excellence between these final two patterns lies in whether or not
any engineer can contribute to the product
crew’s codebase, or solely a small set of trusted exterior
contributors. It is uncommon to see product supply groups make the
funding required to assist the complete inside open-source
strategy, however common for contributions to be accepted by a
handful of trusted platform engineers.
Simply as with taking the file-a-ticket path, having the platform
crew do the work comes with some professionals and cons.
On the plus aspect, this strategy usually reduces the lead time to
get modifications made, as a result of the crew that wants the work to be carried out
(the platform crew) can be the one doing the work. Aligned
incentives imply that the platform crew is more likely to
prioritize their work than the product crew which owns the codebase
would.
On the detrimental aspect, having the platform crew do the migration
work themselves solely works if the product crew can assist
it. They both have to be comfy with a platform engineer
becoming a member of their crew for some time, or they should have already spent
sufficient time with a platform engineer that they belief them to make
modifications to their codebase independently, or they should have made
the numerous funding required to assist an inside
open-source strategy.
One other detrimental is that this do-it-yourself technique is just not
scalable. There’ll at all times be much less engineering capability on the
platform crew in comparison with the product supply groups, and never
delegating engineering work out to the product groups leaves all that
capability on the desk.
Actually, it’s kind of extra sophisticated
In actuality, what usually occurs is a mix of those
approaches. A platform crew tasked with a migration may need
a program supervisor file tickets with 15 product supply groups after which
spend some time frame cajoling them to do the work.
After some time, some groups will
have carried out the work themselves however there might be stragglers who’re
significantly busy with different issues, or simply significantly
disinclined to tackle the migration work. The platform crew will
then roll up their sleeves and use a number of the different, much less scalable
approaches and make the modifications themselves.
Platform Consumption
Now let’s discuss one other part of platform adoption that includes
cross-team collaboration: platform consumption. That is the
“regular state” for platform integration, when a product supply crew
is utilizing platform capabilities as a part of their day-to-day characteristic
work.
One instance of platform consumption could be a product crew
spinning up a brand new service utilizing a service chassis
that is maintained by an infrastructure platform crew. Or a
product crew is perhaps beginning to use an inside buyer analytics
platform, or beginning to retailer PII utilizing a devoted Delicate Information
Retailer service. For example from the opposite finish of the software program stack,
a product crew beginning to use parts from a shared UI element
library is a kind of platform consumption work.
The important thing distinction between platform consumption work vs platform
migration work is that the product crew is each the motive force of the work, and
the proprietor of the codebase that wants altering – the product crew has a broader aim of its
personal, and they’re leveraging the platform’s options to get there. That is in distinction
to platform migration the place the platform crew is attempting to drive modifications into different crew’s codebase.
With platform consumption With the product crew as each driver and proprietor, you would possibly assume that this platform
consumption situation shouldn’t require cross-team collaboration.
Nevertheless, as we’ll see, the product crew can nonetheless want some assist
from the platform crew.
Collaboration patterns
A worthy aim for a lot of platform groups is to construct a completely self-service
platform – one thing like Stripe or Auth0 that’s so well-documented and
simple to make use of that product engineers can use the platform with no need
any direct assist or collaboration with the platform crew.
In actuality, most inside platforms aren’t fairly there,
particularly early on. Product engineers getting began with an
inside platform will usually run into poor documentation, obtuse
error messages, and complicated bugs. Usually these product groups will
throw up their palms and ask the platform crew to pitch in to assist
them get began utilizing the options of an inside platform.
When a platform client is asking the platform proprietor for
hands-on assist we’re again to cross-team collaboration, and as soon as
once more completely different patterns come into play.
Skilled companies
Generally a product crew would possibly ask the platform crew to
write the platform consumption code for them. This is perhaps as a result of
the product crew is struggling to determine the way to use the
platform. Or it might be as a result of this strategy would require much less
effort from the product crew. Generally it is only a misunderstanding
the place the product crew would not assume they’re speculated to do the work
themselves – this may occur when shifting right into a devops mannequin the place
product groups are self-servicing their infra wants, for instance.
On this situation the platform crew form of turns into just a little
skilled companies group inside the engineering org, integrating
their product into their buyer’s techniques on their behalf.
This skilled companies mannequin makes use of a mix of
collaboration patterns. Firstly, a product crew will sometimes File a Ticket
requesting the platform crew’s companies. This is identical
sample we checked out earlier for Platform Migration work, however
inverted – on this state of affairs it is the product crew submitting a ticket
w. the platform crew, asking for his or her assist. The platform crew can
then really carry out the work utilizing both the Trusted Outsider or
Inner Open Supply patterns.
A typical instance of this collaboration mannequin is when a product
crew wants some infrastructure modifications. They wish to spin up a brand new
service, register a brand new exterior endpoint with an API gateway, or
replace some configuration values, so that they file a ticket with a
platform crew asking them to make the suitable modifications.
This sample is often seen within the infra house, as a result of it
perpetuates an present behavior – earlier than self-service infra, submitting
a ticket would have been the usual mechanism for a product crew
to get an infrastructure change made.
White-glove onboarding
For a platform that is in its early levels and missing in good
documentation, a platform crew would possibly choose to onboarding new product
groups utilizing a “white glove” strategy, working side-by-side with
these early adopters to get them began. This may also help kickstart
the adoption of a brand new platform by making it much less onerous for the product
groups who go first. It will probably additionally give a platform crew actually precious
insights into how their first prospects really use the platform’s
options.
This white-glove mannequin is usually achieved utilizing the Tour of Obligation
collaboration sample – a number of platform engineers will
spend a while embedded into the consuming crew, doing the
required platform integration work from inside that crew.
Fingers-on would not scale
We will see that the extent of hands-on assist {that a} platform
crew wants to supply to shoppers can differ lots relying
on how mature a platform’s Developer Expertise is – how nicely it is
documented, how simple it’s to combine and function in opposition to.
Within the early days of a platform, it is sensible for platform
consumption to require numerous vitality from the platform crew
itself. The developer expertise continues to be just a little rocky, platform
capabilities are maybe nonetheless being constructed out, and consuming groups
are maybe just a little skeptical to speculate their very own time as guinea
pigs. What’s extra, working side-by-side with product groups is a
smart way for a platform crew to know their prospects and what
they want!
Nevertheless hands-on assist would not scale, and if broad platform
adoption is the aim then a platform crew should spend money on the
developer expertise of their platform to keep away from drowning in
implementation work.
It is also vital to obviously talk to platform customers what
assist mannequin they need to anticipate. A product crew that has obtained
white-glove assist within the early days of platform adoption will look
ahead to having fun with that have once more sooner or later except
knowledgeable in any other case!
Platform Evolution
Let’s transfer on to have a look at our last platform collaboration part: platform
evolution. That is when a crew utilizing a platform wants modifications within the platform itself, to fill a spot within the platform’s
capabilities.
For instance, a crew utilizing a UI element library
would possibly want a brand new kind of <Button> element to be added, or for
the present <Button> element to be prolonged with extra
configuration choices. Or a crew utilizing a service chassis would possibly need that chassis to emit extra
detailed observability data, or maybe assist a brand new
serialization format.
We will see that in Platform Evolution part the crew’s respective
roles are the alternative of Platform Migration – now it is the product
crew that is driving the work, however the modifications must happen within the
platform crew’s codebase.
Let us take a look at which cross-team
collaboration patterns make sense on this context.
File a ticket
The product crew might File a Ticket with the platform crew,
asking them to make the required modifications to their platform. This
tends to be a really irritating strategy. Usually a product crew solely
realizes that the platform is lacking one thing in the intervening time that
they want it, and the turnaround time for getting the platform crew
to prioritize and carry out the work could be method too lengthy – platform
groups are sometimes overloaded with inbound requests. This results in
the platform crew turning into a bottleneck and blocking the product
supply crew’s progress.
Transfer engineers to the work
With adequate warning, groups can plan to fill a spot in
platform capabilities by briefly re-assigning engineers to work
on the required platform enhancements. Product engineers might do a
Tour of Obligation
on the platform crew, or alternatively a platform engineer might
be part of the product crew for some time as an Embedded Professional.
Transferring engineers between groups will inevitably result in a
short-term influence on productiveness, however having an embedded engineer
can improve effectivity in the long term by lowering the quantity of
cross-team communication that is wanted between the product and the
platform groups. The embedded engineer acts as an envoy,
smoothing the communication pathways and lowering the video games of
phone.
This equation of fastened upfront prices and ongoing advantages means
that re-assigning engineers is an possibility finest reserved for bigger
platform enhancements – shifting an engineer to a different crew for a
couple of weeks could be extra disruptive than useful.
A majority of these momentary assignments additionally require a comparatively
mature administration construction to keep away from embedded engineers feeling
remoted. With an Embedded Professional – a platform engineer re-assigned
to a product crew – there’s additionally a danger that they turn out to be a common
“additional hand” who’s simply doing platform consumption work, reasonably than
actively engaged on the enhancements to the platform that the
product crew want.
Work on the platform from afar
If a platform crew has embraced an Inner Open Supply strategy then a
product crew has the choice of straight implementing the required platform modifications
themselves. The platform crew’s function could be principally consultative,
offering design suggestions and reviewing the product crew’s
PRs. After a number of PRs, a product engineer would possibly even acquire sufficient
belief from the platform crew to be granted the commit bit and turn out to be
a Trusted Outsider.
Many platform groups aspire to get to this case – would not it
be nice in case your prospects have been empowered to implement their very own
enhancements, and prevent from having to do the work! Nevertheless, the
actuality of inside open-source is much like open-source basically
– it takes a stunning quantity of funding to assist exterior
contributions, and the big majority of shoppers do not turn out to be
significant contributors.
Platform groups must be cautious to not open up their codebase to
exterior contributions with out making some considerate investments to
assist these contributions. There could be deep frustration all
round if a platform crew proudly proclaim in an all-hands that
their codebase is a shared useful resource, however then discover themselves
repeatedly telling contributors from different groups “no, no, not like
THAT!”.
Conclusion
Having thought of Platform Migration, Consumption, and Evolution, it is clear that there is a wealthy selection in how
groups collaborate round a platform.
It is also obvious that there is not one right type of collaboration. One of the simplest ways to work collectively relies upon not simply on
what part of platform adoption a crew is in, but in addition on the maturity of the interfaces between groups and between techniques.
Anticipating to have the ability to combine a brand new inside platform in the identical hands-off, as-a-service mode that you simply’d use with a
mature exterior service is a recipe for catastrophe. Likewise, anticipating to have the ability to simply make modifications to a product supply
crew’s codebase once they’ve by no means accepted exterior contributions earlier than is just not an inexpensive assumption to make.
be collaborative, however just for a bit
In Group Topologies, they level out that one of the best ways to design good boundaries between two groups is to initially work collectively
in a centered, very collaborative mode – consider patterns like Embedded Professional and
Tour of Obligation. This era can be utilized to discover the place the perfect boundaries
and interfaces to create between techniques, and between groups (Conway’s Regulation tells us that these two are inextricably entwined).
Nevertheless, the authors of Group Topologies additionally warn that it is vital to not keep on this collaborative mode for too lengthy. A platform
crew must be working exhausting to outline their interfaces, seeking to transfer rapidly to an “as-a-service” mode, utilizing patterns like
File a Ticket and Inner Open Supply. As we mentioned within the Platform Consumption part,
the extra collaborative interplay fashions merely will not scale so far as the platform crew is anxious. Moreover, collaborative modes
impose a a lot higher cognitive load on the consuming groups – shifting to extra hands-off interplay kinds permits product supply groups
to spend extra of their time centered on their very own outcomes. Actually, Group Topologies considers this discount of cognitive load as
the defining objective of a platform crew – a framing which I very a lot agree with.
Navigating this shift from extremely collaborative to as-a-service is, for my part, one of many largest
challenges {that a} younger platform crew faces. Your prospects turn out to be comfy with the high-touch expertise. Constructing nice documentation is difficult.
Saying no is difficult.
Platform groups working in a collaborative mode must be maintaining a climate eye for scaling challenges. As the necessity for a shift
in the direction of a extra scalable, hands-off strategy seems on the horizon the platform crew ought to start signaling this shift to their prospects.
An early warning as to how the interplay mannequin will change – and why – provides product groups an opportunity to organize and to begin
shifting their psychological mannequin of the platform in the direction of one thing that is extra self-sufficient.
The transition could be painful, however vacillating makes it worse. A product supply crew will recognize clearly
communicated guidelines of engagement round how their platform suppliers will assist them. Moreover, eradicating the crutch of hands-on
collaboration supplies a powerful motivation to enhance self-service interfaces, documentation, and so forth. Conway’s Regulation is in impact right here –
redefining how groups combine will put strain on how the crew’s techniques combine.
A platform crew succeeds on the again of collaboration with different groups, and that collaboration can take many varieties. Choosing the proper
type includes contemplating the kind of platform work the opposite crew is doing, and being lifelike concerning the present state of each groups
and their techniques. Getting this proper will enable the platform crew to develop adoption of their platform, however as that adoption grows the
crew should even be intentional in shifting to collaboration modes which can be much less hands-on, extra scalable, and reduce cognitive load for the
shoppers of that platform.
