The success of an inside platform is outlined by what number of groups undertake it. Which means that a
platform crew’s success hangs on their skill to collaborate with different groups, and particularly to get
code adjustments 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 taking a look at 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
greatest in every part.
When contemplating how software program groups collaborate, my go-to useful resource is the fantastic
Workforce Topologies e-book. In chapter 7 the authors
outline three Workforce Interplay Modes: collaboration, X-as-a-service, and facilitating.
There’s, unsurprisingly, some overlap between the fashions I’ll current on this article
and people three Workforce Topology modes, and I will level these out alongside the best way. I will additionally
refer again to a number of the normal knowledge from Workforce Topologies within the conclusion to this
article – it truly is an especially invaluable useful resource when fascinated with 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 forms 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 a corporation’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 tip customers of the platform crew’s product are different groups
throughout the firm. I will be utilizing “platform crew” as a short-hand for “platform supply crew”.
Within the language of Workforce Topologies, a product supply crew would usually be characterised
as a Stream Aligned crew. Whereas the Workforce Topologies authors initially outlined
Platform Workforce as a definite topology, they’ve subsequently come to see “platform”
as a broader idea, moderately than a definite means of working – one thing I very a lot agree with. In
my expertise on the subject of Workforce Topologies terminology an excellent 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. In truth, in lots of the cross-team collaboration patterns we’ll
be taking a look at on this article the platform crew is appearing in that Enabling mode.
“Platform” > Inside Developer Platform
There’s lots of buzz in the intervening time round Platform Engineering, primarily
centered on Inside Developer Platforms (IDPs). I wish to make it clear that
the dialogue of “platforms” right here is considerably broader; it encompasses different inside merchandise
similar to a knowledge platform, a front-end design system, or an experimentation platform.
In truth, whereas we will probably be primarily involved with technical platforms, lots of the concepts
introduced 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’ll 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 taking a look at platform migrations. Migrations contain
adjustments to product groups’ codebases so as to change over to some new
platform functionality.
We see that in these conditions it is a platform crew that is driving the
adjustments, however the possession of the codebase that wants altering is sits with a unique crew – a product crew.
Therefore the necessity for cross-team collaboration.
Examples of migration work
What forms of adjustments are we speaking about? One comparatively easy
migration could be a model upgrade- upgrading a shared part
library, or upgrading a service’s underlying language runtime.
A standard, bigger migration could be changing direct integration of
a third get together system with some inside wrapper – for instance, transferring
logging, analytics, or observability instrumentation over to utilizing a
shared inside library maintained by a platform crew, or changing
direct integration with a cost processor with integration by way of an
inside gateway service of some sort.
One other sort of migration may be changing an present integration right into a deprecated
inside service with an integration into it is alternative – maybe transferring from an outdated Consumer
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 remaining 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.
Be aware that with platform migrations the product crew is commonly not particularly motivated
to make these adjustments. Generally they’re, if the brand new platform goes to offer some
notably 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 may File a Ticket within the
product groups’ backlogs, asking them
to make the required adjustments themselves.
This method has some benefits. It’s scalable – the
implementation work may 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 may be executed by a program supervisor or different mission
administration sort.
Nonetheless, there are additionally some drawbacks. It’s actually gradual –
there will probably 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 may decide to make adjustments to the product crew’s
codebases themselves, utilizing three related however distinct patterns –
Tour of Obligation, Trusted Outsider, or Inside 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 Inside 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
method, 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 execs and cons.
On the plus aspect, this method usually reduces the lead time to
get adjustments made, as a result of the crew that wants the work to be executed
(the platform crew) can also 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 should be snug 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
adjustments to their codebase independently, or they should have made
the numerous funding required to assist an inside
open-source method.
One other detrimental is that this do-it-yourself technique just isn’t
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 difficult
In actuality, what usually occurs is a mixture of those
approaches. A platform crew tasked with a migration might 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 executed the work themselves however there will probably be stragglers who’re
notably busy with different issues, or simply notably
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 adjustments themselves.
Platform Consumption
Now let’s discuss one other part of platform adoption that entails
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 may be beginning to use an inside buyer analytics
platform, or beginning to retailer PII utilizing a devoted Delicate Information
Retailer service. For instance from the opposite finish of the software program stack,
a product crew beginning to use parts from a shared UI part
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 purpose 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 adjustments into different crew’s codebase.
With platform consumption With the product crew as each driver and proprietor, you may suppose that this platform
consumption situation mustn’t require cross-team collaboration.
Nonetheless, as we’ll see, the product crew can nonetheless want some assist
from the platform crew.
Collaboration patterns
A worthy purpose for a lot of platform groups is to construct a totally self-service
platform – one thing like Stripe or Auth0 that’s so well-documented and
straightforward to make use of that product engineers can use the platform while not having
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. Typically these product groups will
throw up their fingers and ask the platform crew to pitch in to assist
them get began utilizing the options of an inside platform.
When a platform shopper 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 may ask the platform crew to
write the platform consumption code for them. This may be as a result of
the product crew is struggling to determine methods to use the
platform. Or it may very well be as a result of this method would require much less
effort from the product crew. Generally it is only a misunderstanding
the place the product crew would not suppose they’re presupposed to do the work
themselves – this could 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 somewhat
skilled companies group throughout the engineering org, integrating
their product into their buyer’s programs on their behalf.
This skilled companies mannequin makes use of a mixture of
collaboration patterns. Firstly, a product crew will usually 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 scenario 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
Inside Open Supply patterns.
A standard instance of this collaboration mannequin is when a product
crew wants some infrastructure adjustments. 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 adjustments.
This sample is usually seen within the infra area, 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 phases and missing in good
documentation, a platform crew may decide to onboarding new product
groups utilizing a “white glove” method, working side-by-side with
these early adopters to get them began. This might help kickstart
the adoption of a brand new platform by making it much less onerous for the product
groups who go first. It could additionally give a platform crew actually invaluable
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.
Palms-on would not scale
We will see that the extent of hands-on assist {that a} platform
crew wants to offer to customers can differ so much relying
on how mature a platform’s Developer Expertise is – how nicely it is
documented, how straightforward it’s to combine and function towards.
Within the early days of a platform, it is sensible for platform
consumption to require lots of vitality from the platform crew
itself. The developer expertise remains to be somewhat rocky, platform
capabilities are maybe nonetheless being constructed out, and consuming groups
are maybe somewhat skeptical to take a position their very own time as guinea
pigs. What’s extra, working side-by-side with product groups is a
good way for a platform crew to grasp their prospects and what
they want!
Nonetheless hands-on assist would not scale, and if broad platform
adoption is the purpose then a platform crew should put money into 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 count on. A product crew that has acquired
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 take a look at our remaining platform collaboration part: platform
evolution. That is when a crew utilizing a platform wants adjustments within the platform itself, to fill a niche within the platform’s
capabilities.
For instance, a crew utilizing a UI part library
may want a brand new sort of <Button> part to be added, or for
the prevailing <Button> part to be prolonged with further
configuration choices. Or a crew utilizing a service chassis may need that chassis to emit extra
detailed observability info, 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 adjustments have to happen within the
platform crew’s codebase.
Let’s take a look at which cross-team
collaboration patterns make sense on this context.
File a ticket
The product crew may File a Ticket with the platform crew,
asking them to make the required adjustments to their platform. This
tends to be a really irritating method. Typically 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 may be means too lengthy – platform
groups are usually 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 ample warning, groups can plan to fill a niche in
platform capabilities by briefly re-assigning engineers to work
on the required platform enhancements. Product engineers may do a
Tour of Obligation
on the platform crew, or alternatively a platform engineer may
be part of the product crew for some time as an Embedded Knowledgeable.
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 choice greatest reserved for bigger
platform enhancements – transferring an engineer to a different crew for a
couple of weeks could be extra disruptive than useful.
A majority of these non permanent assignments additionally require a comparatively
mature administration construction to keep away from embedded engineers feeling
remoted. With an Embedded Knowledgeable – a platform engineer re-assigned
to a product crew – there’s additionally a danger that they develop into a normal
“additional hand” who’s simply doing platform consumption work, moderately 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 Inside Open Supply method then a
product crew has the choice of immediately implementing the required platform adjustments
themselves. The platform crew’s function could be largely consultative,
offering design suggestions and reviewing the product crew’s
PRs. After just a few PRs, a product engineer may even acquire sufficient
belief from the platform crew to be granted the commit bit and develop into
a Trusted Outsider.
Many platform groups aspire to get to this case – would not it
be nice in case your prospects had been empowered to implement their very own
enhancements, and prevent from having to do the work! Nonetheless, the
actuality of inside open-source is much like open-source on the whole
– it takes a shocking quantity of funding to assist exterior
contributions, and the big majority of customers do not develop into
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 may 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-about 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 additionally on the maturity of the interfaces between groups and between programs.
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 adjustments to a product supply
crew’s codebase once they’ve by no means accepted exterior contributions earlier than just isn’t an affordable assumption to make.
be collaborative, however just for a bit
In Workforce Topologies, they level out that one of the simplest ways to design good boundaries between two groups is to initially work collectively
in a centered, very collaborative mode – consider patterns like Embedded Knowledgeable and
Tour of Obligation. This era can be utilized to discover the place the perfect boundaries
and interfaces to create between programs, and between groups (Conway’s Legislation tells us that these two are inextricably entwined).
Nonetheless, the authors of Workforce Topologies additionally warn that it is vital to not keep on this collaborative mode for too lengthy. A platform
crew must be working laborious to outline their interfaces, trying to transfer rapidly to an “as-a-service” mode, utilizing patterns like
File a Ticket and Inside 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 – transferring to extra hands-off interplay kinds permits product supply groups
to spend extra of their time centered on their very own outcomes. In truth, Workforce Topologies considers this discount of cognitive load as
the defining goal 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 greatest
challenges {that a} younger platform crew faces. Your prospects develop into snug with the high-touch expertise. Constructing nice documentation is difficult.
Saying no is difficult.
Platform groups working in a collaborative mode must be protecting a climate eye for scaling challenges. As the necessity for a shift
in the direction of a extra scalable, hands-off method 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 arrange and to begin
shifting their psychological mannequin of the platform in the direction of one thing that is extra self-sufficient.
The transition may be painful, however vacillating makes it worse. A product supply crew will respect clearly
communicated guidelines of engagement round how their platform suppliers will assist them. Moreover, eradicating the crutch of hands-on
collaboration offers a robust motivation to enhance self-service interfaces, documentation, and so forth. Conway’s Legislation is in impact right here –
redefining how groups combine will put stress on how the crew’s programs combine.
A platform crew succeeds on the again of collaboration with different groups, and that collaboration can take many types. Selecting the best
type entails contemplating the kind of platform work the opposite crew is doing, and being lifelike in regards to the present state of each groups
and their programs. 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 transferring to collaboration modes which might be much less hands-on, extra scalable, and decrease cognitive load for the
customers of that platform.
