Title: The Shape of the Serviceable Line: Not Every Offering Has Five Layers Description: How far do your customers, and their AI, get without you? The five layers are not the same size for every offering, so the Serviceable Line has a shape, and so does the work around it. [The Serviceable Line](https://etgarbonar.com/serviceable-line/) · Part two # The shape of the Serviceable Line How far do your customers, and their AI, get without you? The five layers are not the same size for every offering. A bag of rice has almost nothing to connect or fix. A medical device has a hospital committee to convince and technicians to train. A software platform has all five, in depth. So the line has a shape, and so does the work around it. Published 3 October 2026 · Updated 15 October 2026 · 7 minute read - The surface: what your offering asks of someone - The Serviceable Line - Carried by your customers - Carried by their AI - Your people step in, or revenue is lost Illustrative: three of the six offerings below, in turn. A bar's length is what the offering asks on that layer. What matters is the gap on each bar, the part past the line, not which bar is longest. Every offering asks something of the person buying it. Some ask almost nothing. Some ask a great deal, before the purchase and long after it. The Serviceable Line is how far your customers, and increasingly their AI, get with your offering on their own. That distance only means something against how much there is to get through. So before asking where your line sits, ask how big your surface is. How to read the shape ## A surface, a line and a gap Each bar is one of the five layers: Findable, Selectable, Integrable, Operable and Fixable. Integrable gets the offering into the customer's environment. Operable gets the customer's work done once it is there. Three things sit on each bar. The surface Everything someone has to work out or do to get value from your offering, on each layer: where to find it, how it compares, what it has to connect to, how to run it, and what to do when it goes wrong. A long bar means a lot of work on that layer. No bar means the layer does not exist for this offering. The line How much of that surface your customers, and increasingly their AI, get through on their own. It ends at the Serviceable Line, the mark on each bar. On the drawings, blue is what customers carry and gold is what their AI carries. The gap Everything past the line. One of two things happens there: **One of your people steps in.** This is seen and costed: your cost to sell and to serve. **The customer is lost.** This ranges from invisible (left out of an AI answer, never entered the funnel), to seen as a number without its cause (a trial that did not convert, churn, a deal that went small), to seen and explained, which happens only when a person was there. Grey on the drawings. Moving the line out shrinks the gap from the inside. How much there is to shrink depends on the offering. ### The scale Every bar on this page is scored on one scale, for the surface, the line, the part of it their AI carries and what others carry, so two people draw the same offering the same way. 1. **0** Nothing to do. The layer does not exist for this offering. 2. **1** A few facts to look up. 3. **2** A procedure to follow. 4. **3** A system to configure and keep running. One journey, two providers ## See the five layers move through one trip Follow the same traveler across two fictional booking platforms, from being found to recovering when something breaks. [See the flight example](https://etgarbonar.com/serviceable-line/examples/flight/) Before comparing offerings ## A partner can carry work too The Serviceable Line stays where your customers and their AI can get on their own. Sometimes a dealer, distributor, implementation partner, service company or third-party site carries work past that line. That does not move the line. It explains who carries part of the remaining surface. In the comparisons below, teal marks that partner-carried work. Grey is what still requires your people, or becomes revenue lost. Six offerings ## Six offerings, six shapes - The surface - The Serviceable Line - Carried by your customers - Carried by their AI - Carried by a partner or someone else - Your people step in, or revenue is lost Bag of rice Two short layers, each a few facts to look up, and the retailer carries most of both. Integrable and Fixable score zero: nothing to connect, nothing to fix. Cordless drill The battery platform is an Integrable layer. Error lights and spare parts make Fixable a procedure to follow. Forums and repair sites carry what the maker does not publish. Payments platform Authentication and a working sandbox connection are Integrable, a system to configure and keep running. Creating and verifying a payment are Operable. Required onboarding checks and payment disputes hold the line in, whatever the AI can do. Platforms that resell payments carry part of it. Medical device The longest Selectable: clinical evidence, approvals and a hospital committee. Distributors and hospital technicians carry much of the rest, and the AI doing that work is theirs, not the buyer's. Clinic A service has a surface too: coverage, preparation, follow-up and the bill. Insurer directories and booking sites answer part of it. API-first software All five layers, each at the top of the scale, and the one shape where every layer can be tested from outside today. Review sites and implementation partners carry part of it. These shapes are illustrative, scored on the scale above. They vary by the specific type of offering and buyer segment. What the shapes show ## What the shapes make plain ### Industry is the wrong cut The question is the shape of the offering, not the sector it sits in. A cordless drill shares more layers with a software product than with a bag of rice, though the drill and the rice are both consumer goods. ### A missing layer is not a failing score The rice is not bad at Fixable. It has nothing to fix. Judge each offering only against the surface it has, or every simple product looks like it is failing. ### Findable stays a battleground For anything that is not a commodity, Findable is a contest for a few places, and like search before it, it is never settled, because every competitor is fighting for the same answer. An AI answer usually names a handful of options, not a page of ten links. ### Selectable is where the newest silent loss happens When price, limits and fit criteria are missing, the AI compares you against a smaller version of yourself, or fills in the blanks with someone else's numbers. The longer the Selectable bar, the more that costs. The first move is to publish them as plain facts a machine can quote, and to track how accurately the buyer's AI compares you. ### In regulated offerings, the rules hold the line in On a payments platform or a medical device, some layers stay short whatever the customer's AI can do, because a regulator, a committee or the cost of error requires a person. That is the buyer side of the two variables: gated by permission, accountability, regulation and the cost of error, not by what the models can do. A permutation ## When someone else carries the work Partnerships, after-sales services, agencies, dealers, integrators and repair sites are not a separate model. They are a permutation of this one: part of the surface past your line is carried by someone who is neither you nor your customer. On the drawings, that is the teal. That work is partly seen. It gets done, but you are leaking margin, control and the record the next buyer's AI reads. Sometimes nobody asked them to carry it: if you do not publish the answer, the AI gets it elsewhere, such as price from review sites, compatibility from forums, or the repair from a repair site. iFixit already offers an [AI repair assistant](https://www.ifixit.com/News/114700/introducing-fixbot) for products whose makers left that layer empty. And the AI doing that work is not always the buyer's. On a medical device, much of the fixing is done by a distributor's or the hospital's own technician, increasingly with their own AI. The question does not change: how far does the work get before one of your people has to step in? ### Bring it in-house When your offering carries more on its own, some of the work a middleman did for a fee comes back to you, and so does the margin. ### Or make them better at it The documentation, interfaces and recovery paths that move your line also make your partners faster. A partner whose work gets easier sells and services more of you. Which move fits is a channel decision. Either way, it starts with the same work: an offering legible enough to be carried without you. One offering, two buyers ## The surface belongs to the buyer, too The same software, sold to a small business and to an enterprise, has two different surfaces. The enterprise adds a security review, procurement and connections to many systems. At the small business, the person evaluating it is often the person buying it and the person setting it up, in the same afternoon. Sold to a small business A smaller surface, and the line close to its edge. Sold to an enterprise Security review, procurement and many systems to connect: a bigger surface, systems integrators carrying part of it, and a bigger gap. So the line is set per buyer segment, not per company. That is also why the two variables behind it are read per buyer, not per industry. How far AI moves the line depends on two things, and neither works without the other: how far your buyers have gone in handing this work to AI, and how legible your offering is to a machine. How it plays out ## Both edges are moving This section is forecast, not evidence. ### The surfaces grow Goods are becoming software-defined. The drill gets an app, the appliance gets firmware, the car gets updates. Each one adds Integrable, Operable and Fixable surface to something that had little. ### So the gap can grow while the line moves out Whether your gap shrinks depends on which edge moves faster: the line, as customers and their AI get further alone, or the surface, as the offering asks more of them. A drill today The cordless drill from the six offerings above. The same drill, software-defined An app, firmware updates and tool tracking. The surface grew on four layers, the line moved less, so the gap grew. ### The layers move at different speeds Findable stays contested. Selectable is where the losses are moving now. On Integrable and Fixable, consumers already ask their AI the questions before they buy, but they do not hand it the doing, so the line moves through content first: compatibility lists, manuals and parts lists. Operable moves last, because it is gated by permission, accountability and the cost of error, not by what the models can do. ### Regulation is publishing some surfaces by force From 31 July 2026, the [EU Right to Repair Directive](https://eur-lex.europa.eu/eli/dir/2024/1799/oj) requires producers of covered products, such as washing machines, refrigerators and phones, to offer repair beyond the guarantee, with repair information and spare parts to match. It was written as sustainability law. It also builds part of the record a customer's AI reads. Use it ## Draw your own shape 1. For each layer, list what a buyer has to work out or do with your offering. If the list is empty, the layer does not exist for you. That is your surface. 2. For each item, ask whether your customers, or their AI, can get through it from what you publish, without a person. That is your line. Mark the part their AI already does. 3. If partners, dealers, service companies or third-party sites carry part of it, mark that too. 4. What is left is your gap: the work your people carry, and the customers you lose, often without seeing why. 5. Draw it once per buyer segment, not once per company. Score each layer on the 0 to 3 scale under How to read the shape, so two people draw the same offering the same way. Compare offerings layer by layer, and look at the gap: it is what costs you, not the length of the bar. Start here ## The Serviceable Line The full argument: what the line is, the five questions the customer's AI keeps asking, the losses no funnel records, and how the line was moved by hand before AI.
