The success of an inner platform is outlined by what number of groups undertake it. Which means that a
platform staff’s success hangs on their capacity 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 totally different
collaboration phases that platform groups are inclined 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 totally different in every of those phases,
talk about 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 great
Staff Topologies e book. In chapter 7 the authors
outline three Staff 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 Staff Topology modes, and I will level these out alongside the way in which. I will additionally
refer again to a few of the basic knowledge from Staff Topologies within the conclusion to this
article – it truly is an especially worthwhile useful resource when serious 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 staff
from different varieties of engineering staff. On this dialogue I’ll usually check with
product supply groups and platform supply groups.
A product supply staff 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 most of these engineering staff known as a “characteristic
staff”, a “product staff” or a “vertical staff”. On this article I will use
“product staff” as a shorthand for product supply staff.
In distinction, a platform supply staff builds merchandise for different groups contained in the
firm – the tip customers of the platform staff’s product are different groups
inside the firm. I will be utilizing “platform staff” as a short-hand for “platform supply staff”.
Within the language of Staff Topologies, a product supply staff would usually be characterised
as a Stream Aligned staff. Whereas the Staff Topologies authors initially outlined
Platform Staff as a definite topology, they’ve subsequently come to see “platform”
as a broader idea, slightly than a definite method of working – one thing I very a lot agree with. In
my expertise in relation to Staff Topologies terminology a superb platform tends to function as both
a Stream Aligned staff – with their platform being their worth stream – or as an Enabling staff, serving to
different groups to succeed with their platform. The truth is, in most of the cross-team collaboration patterns we’ll
be taking a look at on this article the platform staff is performing in that Enabling mode.
“Platform” > Inner Developer Platform
There’s a whole lot of buzz in the meanwhile round Platform Engineering, primarily
targeted on Inner Developer Platforms (IDPs). I wish to make it clear that
the dialogue of “platforms” right here is considerably broader; it encompasses different inner merchandise
equivalent to an information platform, a front-end design system, or an experimentation platform.
The truth is, whereas we can be primarily involved with technical platforms, a whole lot of the concepts
introduced right here additionally apply to inner 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 inner 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 essential to notice two particular
traits: which staff is driving the work, and which staff owns
the codebase the place the work will occur. The solutions to these two
questions drastically have an effect on which collaboration patterns make sense in every
state of affairs.
Platform Migrations
We’ll begin by taking a look at platform migrations. Migrations contain
modifications to product groups’ codebases with a purpose to change over to some new
platform functionality.
We see that in these conditions it is a platform staff that is driving the
modifications, however the possession of the codebase that wants altering is sits with a special staff – a product staff.
Therefore the necessity for cross-team collaboration.
Examples of migration work
What varieties of modifications are we speaking about? One comparatively easy
migration can be a model upgrade- upgrading a shared part
library, or upgrading a service’s underlying language runtime.
A standard, bigger migration can be changing direct integration of
a third social gathering system with some inner wrapper – for instance, shifting
logging, analytics, or observability instrumentation over to utilizing a
shared inner library maintained by a platform staff, or changing
direct integration with a fee processor with integration by way of an
inner gateway service of some variety.
One other sort of migration is perhaps changing an present integration right into a deprecated
inner service with an integration into it is substitute – maybe shifting 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 can be an infrastructure-level re-platforming –
dockerizing a service owned by a product staff, introducing a service
mesh, switching a service’s database from MySQL to Postgres, that kind
of factor.
Word that with platform migrations the product staff is commonly not particularly motivated
to make these modifications. Typically 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 staff may File a Ticket within the
product groups’ backlogs, asking them
to make the required modifications themselves.
This method has some benefits. It’s scalable – the
implementation work might be farmed out to all of the product groups whose
codebases want work. It’s additionally trackable and straightforward to handle – usually
the ticket submitting might be carried out by a program supervisor or different challenge
administration sort.
Nevertheless, there are additionally some drawbacks. It’s actually sluggish –
there can be lengthy lead occasions 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 staff does the work
The platform staff may choose to make modifications to the product staff’s
codebases themselves, utilizing three comparable however distinct patterns –
Tour of Obligation, Trusted Outsider, or Inner Open Supply.
With Tour of Obligation, an engineer from the
platform staff would “embed” with the product staff and do the work
from there.
With Trusted Outsider and Inner Open Supply the product staff would settle for pull
requests to their codebase from an engineer within the platform staff.
The excellence between these final two patterns lies in whether or not
any engineer can contribute to the product
staff’s codebase, or solely a small set of trusted exterior
contributors. It is uncommon to see product supply groups make the
funding required to help the complete inner open-source
method, however commonplace for contributions to be accepted by a
handful of trusted platform engineers.
Simply as with taking the file-a-ticket path, having the platform
staff do the work comes with some execs and cons.
On the plus facet, this method usually reduces the lead time to
get modifications made, as a result of the staff that wants the work to be carried out
(the platform staff) can also be the one doing the work. Aligned
incentives imply that the platform staff is more likely to
prioritize their work than the product staff which owns the codebase
would.
On the unfavourable facet, having the platform staff do the migration
work themselves solely works if the product staff can help
it. They both have to be comfy with a platform engineer
becoming a member of their staff 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 help an inner
open-source method.
One other unfavourable is that this do-it-yourself technique will not be
scalable. There’ll at all times be much less engineering capability on the
platform staff 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 is a bit extra difficult
In actuality, what usually occurs is a mixture of those
approaches. A platform staff tasked with a migration may need
a program supervisor file tickets with 15 product supply groups after which
spend some time period cajoling them to do the work.
After some time, some groups will
have carried out the work themselves however there can be stragglers who’re
notably busy with different issues, or simply notably
disinclined to tackle the migration work. The platform staff will
then roll up their sleeves and use a few 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 entails
cross-team collaboration: platform consumption. That is the
“regular state” for platform integration, when a product supply staff
is utilizing platform capabilities as a part of their day-to-day characteristic
work.
One instance of platform consumption can be a product staff
spinning up a brand new service utilizing a service chassis
that is maintained by an infrastructure platform staff. Or a
product staff is perhaps beginning to use an inner buyer analytics
platform, or beginning to retailer PII utilizing a devoted Delicate Knowledge
Retailer service. For instance from the opposite finish of the software program stack,
a product staff beginning to use parts from a shared UI part
library is a sort of platform consumption work.
The important thing distinction between platform consumption work vs platform
migration work is that the product staff is each the motive force of the work, and
the proprietor of the codebase that wants altering – the product staff 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 staff is making an attempt to drive modifications into different staff’s codebase.
With platform consumption With the product staff as each driver and proprietor, you may assume that this platform
consumption state of affairs mustn’t require cross-team collaboration.
Nevertheless, as we’ll see, the product staff can nonetheless want some help
from the platform staff.
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
straightforward to make use of that product engineers can use the platform with no need
any direct help or collaboration with the platform staff.
In actuality, most inner platforms aren’t fairly there,
particularly early on. Product engineers getting began with an
inner platform will usually run into poor documentation, obtuse
error messages, and complicated bugs. Typically these product groups will
throw up their palms and ask the platform staff to pitch in to assist
them get began utilizing the options of an inner platform.
When a platform client is asking the platform proprietor for
hands-on help we’re again to cross-team collaboration, and as soon as
once more totally different patterns come into play.
Skilled providers
Typically a product staff may ask the platform staff to
write the platform consumption code for them. This is perhaps as a result of
the product staff is struggling to determine tips on how to use the
platform. Or it might be as a result of this method would require much less
effort from the product staff. Typically it is only a misunderstanding
the place the product staff does not assume they’re speculated to do the work
themselves – this will occur when shifting right into a devops mannequin the place
product groups are self-servicing their infra wants, for instance.
On this state of affairs the platform staff type of turns into just a little
skilled providers group inside the engineering org, integrating
their product into their buyer’s methods on their behalf.
This skilled providers mannequin makes use of a mixture of
collaboration patterns. Firstly, a product staff will usually File a Ticket
requesting the platform staff’s providers. This is identical
sample we checked out earlier for Platform Migration work, however
inverted – on this state of affairs it is the product staff submitting a ticket
w. the platform staff, asking for his or her assist. The platform staff can
then really carry out the work utilizing both the Trusted Outsider or
Inner Open Supply patterns.
A standard instance of this collaboration mannequin is when a product
staff 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, in order that they file a ticket with a
platform staff asking them to make the suitable modifications.
This sample is often 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 staff
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 staff may choose to onboarding new product
groups utilizing a “white glove” method, 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 may additionally give a platform staff actually worthwhile
insights into how their first prospects really use the platform’s
options.
This white-glove mannequin is often achieved utilizing the Tour of Obligation
collaboration sample – a number of platform engineers will
spend a while embedded into the consuming staff, doing the
required platform integration work from inside that staff.
Arms-on does not scale
We are able to see that the extent of hands-on help {that a} platform
staff wants to offer to customers can fluctuate loads 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 a whole lot of power from the platform staff
itself. The developer expertise remains 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
good way for a platform staff to know their prospects and what
they want!
Nevertheless hands-on help does not scale, and if broad platform
adoption is the aim then a platform staff should spend money on the
developer expertise of their platform to keep away from drowning in
implementation work.
It is also essential to obviously talk to platform customers what
help mannequin they need to anticipate. A product staff that has acquired
white-glove help within the early days of platform adoption will look
ahead to having fun with that have once more sooner or later until
knowledgeable in any other case!
Platform Evolution
Let’s transfer on to have a look at our remaining platform collaboration part: platform
evolution. That is when a staff utilizing a platform wants modifications within the platform itself, to fill a niche within the platform’s
capabilities.
For instance, a staff utilizing a UI part library
may want a brand new sort of <Button> part to be added, or for
the present <Button> part to be prolonged with extra
configuration choices. Or a staff utilizing a service chassis may need that chassis to emit extra
detailed observability data, or maybe help a brand new
serialization format.
We are able to see that in Platform Evolution part the staff’s respective
roles are the alternative of Platform Migration – now it is the product
staff that is driving the work, however the modifications must happen within the
platform staff’s codebase.
Let us take a look at which cross-team
collaboration patterns make sense on this context.
File a ticket
The product staff may File a Ticket with the platform staff,
asking them to make the required modifications to their platform. This
tends to be a really irritating method. Typically a product staff solely
realizes that the platform is lacking one thing in the meanwhile that
they want it, and the turnaround time for getting the platform staff
to prioritize and carry out the work might be method too lengthy – platform
groups are usually overloaded with inbound requests. This results in
the platform staff turning into a bottleneck and blocking the product
supply staff’s progress.
Transfer engineers to the work
With enough 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 staff, or alternatively a platform engineer may
be part of the product staff for some time as an Embedded Professional.
Transferring engineers between groups will inevitably result in a
short-term impression on productiveness, however having an embedded engineer
can enhance effectivity in the long term by decreasing 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 decreasing the video games of
phone.
This equation of fastened upfront prices and ongoing advantages means
that re-assigning engineers is an possibility greatest reserved for bigger
platform enhancements – shifting an engineer to a different staff for a
couple of weeks can be extra disruptive than useful.
A lot of these short-term 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 staff – there’s additionally a threat that they turn into a basic
“additional hand” who’s simply doing platform consumption work, slightly than
actively engaged on the enhancements to the platform that the
product staff want.
Work on the platform from afar
If a platform staff has embraced an Inner Open Supply method then a
product staff has the choice of immediately implementing the required platform modifications
themselves. The platform staff’s function can be largely consultative,
offering design suggestions and reviewing the product staff’s
PRs. After just a few PRs, a product engineer may even achieve sufficient
belief from the platform staff to be granted the commit bit and turn into
a Trusted Outsider.
Many platform groups aspire to get to this example – 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 inner open-source is just like open-source normally
– it takes a shocking quantity of funding to help exterior
contributions, and the massive majority of customers do not turn into
significant contributors.
Platform groups must be cautious to not open up their codebase to
exterior contributions with out making some considerate investments to
help these contributions. There might be deep frustration all
round if a platform staff 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 appropriate type of collaboration. One of the best ways to work collectively relies upon not simply on
what part of platform adoption a staff is in, but in addition on the maturity of the interfaces between groups and between methods.
Anticipating to have the ability to combine a brand new inner platform in the identical hands-off, as-a-service mode that you just’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
staff’s codebase once they’ve by no means accepted exterior contributions earlier than will not be an affordable assumption to make.
be collaborative, however just for a bit
In Staff Topologies, they level out that one of the simplest ways to design good boundaries between two groups is to initially work collectively
in a targeted, very collaborative mode – consider patterns like Embedded Professional and
Tour of Obligation. This era can be utilized to discover the place the very best boundaries
and interfaces to create between methods, and between groups (Conway’s Legislation tells us that these two are inextricably entwined).
Nevertheless, the authors of Staff Topologies additionally warn that it is essential to not keep on this collaborative mode for too lengthy. A platform
staff must be working laborious to outline their interfaces, seeking to transfer shortly 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 staff is worried. 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 targeted on their very own outcomes. The truth is, Staff Topologies considers this discount of cognitive load as
the defining objective of a platform staff – 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 staff faces. Your prospects turn into comfy with the high-touch expertise. Constructing nice documentation is tough.
Saying no is tough.
Platform groups working in a collaborative mode must be holding a climate eye for scaling challenges. As the necessity for a shift
in direction of a extra scalable, hands-off method seems on the horizon the platform staff ought to start signaling this shift to their prospects.
An early warning as to how the interplay mannequin will change – and why – offers product groups an opportunity to arrange and to begin
shifting their psychological mannequin of the platform in direction of one thing that is extra self-sufficient.
The transition might be painful, however vacillating makes it worse. A product supply staff will recognize clearly
communicated guidelines of engagement round how their platform suppliers will help 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 staff’s methods combine.
A platform staff succeeds on the again of collaboration with different groups, and that collaboration can take many varieties. Selecting the best
kind entails contemplating the kind of platform work the opposite staff is doing, and being practical concerning the present state of each groups
and their methods. Getting this proper will permit the platform staff to develop adoption of their platform, however as that adoption grows the
staff should even be intentional in shifting to collaboration modes which might be much less hands-on, extra scalable, and decrease cognitive load for the
customers of that platform.
