The method, one term at a time.
Every framework here is taught at Cranfield and used on real accounts, and the AI vocabulary is the part of it a key account manager actually meets. Each page says what the term means, where it sits in the method, and where it is set out in full. Use them in your own plans; the words are not the hard part.
A market segment of one
Treat the key account as a market: the wallet is the market size, your current sales are your share, and the gap is the prize.
ABCDE
Audience, behaviour, content, delivery, evaluation: the five questions for planning any value pitch.
AI agent
Software that takes a goal, plans the steps, uses tools and keeps working until it is done. On the buyer's side it is the procurement of the future; on yours it maintains the plan.
AI fluency
Comfort with the tools, held alongside knowledge of the customer. Hold only the second and you are slow; hold only the first and you are fast, fluent and confidently wrong.
AI tells
The phrases, rhythms and structures that mark text as machine-written. A customer who spots one stops reading the argument and starts reading the author.
Assurance
The corner of the proposition that answers why should I believe you: credibility, return on investment, and the measures both sides will use.
Automation bias
The human tendency to trust the machine even when it is wrong. The danger is not that AI replaces your expertise but that it lulls it into disuse.
Better before cheaper
Raynor and Ahmed's first rule of exceptional companies. The value proposition is the instrument for competing on better.
Causal ambiguity
Advantage that even the company holding it cannot fully explain. AI copies the explicit and cannot copy the ambiguous, so this is where advantage now lives.
Competitive edge
Two conditions, both required: you add measurable value to the customer, and the customer sees you as better value than the alternatives.
Context window
The model's working memory: everything it can see at once, including your prompt, the documents you attach and the conversation so far.
Copilot to autopilot
A copilot suggests, drafts and assists beside the human. An autopilot takes the controls on whole tasks. The line between them is drawn by judgement.
CPIs and KPIs
Critical performance indicators are the critical few, tied to your points of difference. KPIs are the important many. If everything is critical, nothing is.
Customer lifetime value
Five or ten years of profit from the account, after the cost to serve, discounted into today's money and risk-adjusted. The smaller number is the one a board believes.
Customer management
How current and strategic your knowledge of each key customer is, against whether your offers address their problems or promote your capabilities.
Customer needs analysis
The diagnosis. Contextual intelligence about the customer's world, analytical depth about the problems underneath the problems, and clarity about who feels them.
Customer value proposition
The answer to the customer's one real question: what is this worth to me? Said in two sentences, in their financial language.
Decision-making unit (DMU)
The people who decide, influence, use, pay for and can veto a purchase. Mapped as roles, dispositions and relationships, not job titles.
Embracing AI
Adoption against commercial benefit. Adoption without direction is expensive noise.
FOMU
Fear of messing up: stronger than fear of missing out, and the reason 40 to 60% of qualified deals end in no decision.
Hallucination
A confident, well-formed answer that is simply false. Worst on multi-step reasoning and specialised domains, which describes key account work exactly.
High-impact value proposition
Speaks to a problem the customer actually has, is specific enough to be hard to copy, and carries proof.
Human in the loop
Adopt, but keep your hands on the wheel. The machine amplifies judgement. It does not supply it.
Infinite and finite value
A discount is finite: value transferred, not created. Climb from saving money to making it to protecting the business, and the pie itself gets bigger.
Key account management
The continuous delivery of value through the intersection of sales, strategy and innovation.
Machine buying
B2B purchasing done by software agents on the buyer's side. Around a third of it by 2030, and the transactional layer of selling with it.
Offer Development and Innovation (ODI)
The capability to repeatedly create propositions a competitor cannot copy. Three phases: needs analysis, offer ideation, value proposition.
Offer ideation
Diverge before you converge. The machine's gift is width; the cull is yours.
Performance review
Not an audit of a document. A working session on a living strategy, run as coaching rather than inspection.
Portfolio classification
Key Local, Key Regional, Key Global, Key Strategic. The segment sets how high the skills bar sits; the account's situation sets which skills lead.
Preference, competence, capability
Preference is what you are drawn to. Competence is how good you are. Capability belongs to the organisation. Blur them and the assessment is worthless.
Price, cost and value
Three words treated as if they were the same. Price is what the customer pays; cost is what it takes you to produce; value is the only one the customer cares about.
Prompt
The instruction you give an AI model. The single biggest factor in the quality of what comes back. Also, in the book, a structured question you ask yourself.
Retrieval-augmented generation
The model reads your files afresh to answer each question. It works, but nothing accumulates. Each answer starts from a blank page.
Selling twice
In a value-based approach you sell every offer twice: once to your own leadership, then to the customer. An offer not sold inside your company is a rumour.
Share of wallet
Everything a customer spends, could spend or should spend on your category, in four parts: with you, with your competitors, themselves, and what they should do but do not.
Sponsor
The senior person on the customer side who wants you to win and will say so when you are not in the room. Also used for the internal sponsor an offer needs to survive.
Supplier value capture
The mirror image of customer value capture, and the half suppliers forget on purpose: growth, margin and strategic value back to your own business.
System prompt
The standing instructions a model runs on before any user speaks: its role, rules, tone and knowledge base. In the method's tools, the schema is the system prompt.
The 3M test
Material, margin, momentum: the three questions an offer has to pass with your own leadership before it is pitched to a customer.
The 7-P Offer Navigator
The marketing mix repurposed as the anatomy of an offer. Product and price are the shop window; the other five are the workshop, and the hardest to copy.
The baseline
The measure agreed before delivery starts. Value measured against a remembered past is value the customer will dispute.
The commodity trap
The gravity in business markets that pulls every offer towards sameness. AI has made it stronger by stripping the scarcity out of capability.
The dark funnel
The research, comparison and elimination that decides your fate now happens inside AI conversations you cannot see.
The five ages of AI
Prompt, agent, collaborator, advisor, architect. Where you are, where the work is going, and which end is still informed speculation.
The five characteristics of an AI-powered account plan
Productive, creative, collaborative, dynamic, reductive. The last is the one the profession discusses least and probably matters most.
The five pressures
Volatility, changing buyers, machine buying, shorter product lives and geopolitics, arriving together. Suppliers have to trim their sails more often.
The five sources of value
Bottom line, top line, reputation, strategy and organisation, and the end consumer. Everything above the discount, which is transfer, not creation.
The four rungs
Foundational, Established, Advanced, Master. Every sub-skill in the Tri-Stack is scored on the same ladder, and a rung is always backed by evidence.
The future state
The customer's business as it will be once your promise is kept, described in their world and not yours. The centre of the wheel, in a dozen words.
The innovation-obsolescence cycle
A product peaks within a year or two, then falls around 30% a year. Every launch ages the rest of the portfolio, so you launch to stand still.
The KAM Skills Tri-Stack
Strategist, Business Developer, Operator: three skill domains, four sub-skills each, mapped to the three stages of the cycle. Almost nobody is trained for all three.
The living account plan
Something closer to a brain than a binder: an account plan an AI maintains from raw sources, against your methodology, so it is current when you open it.
The LLM wiki
Karpathy's pattern: the AI keeps a set of interlinked pages current as sources arrive, so knowledge is compiled once and maintained, not rebuilt on every question.
The offer
Everything a supplier does for a customer: products, services, prices, people, processes and proof. Not what the customer gets, but how they get it.
The Offer Wheel
The map of the whole value system around one customer, built inside-out, that compresses into the one-page proposition.
The offer, the person, the culture
The most important thing, the most important person and the hardest thing. The trio every KAM programme has to get right.
The schema
The set of rules that turns a generic chatbot into a disciplined maintainer of your account plan. For a KAM, the schema is your sales methodology.
The six characters
Two questions, six readers: how fluent you are with AI, and whether your instinct is to reach for the tool or for the customer.
The Strategic Customer Planning Cycle
ODI, value sell, value capture: three stages run as a compounding loop, at the level of a sector, a channel or a single key customer.
The three registers
Productive, creative, collaborative: three different jobs AI can do for an account team. Not a maturity ladder, and the collaborative one needs an expert in the loop.
The three rings
The customer's future state at the centre, the value they receive around it, your products in the outer ring. Customers buy the centre; suppliers sell the outside.
The trust equation
Credibility plus reliability plus intimacy, divided by self-orientation. Promise five and deliver three and you have helped the customer and damaged the relationship.
The twelve questions
The interrogation a sharp executive would run on any account plan. Start at the end: the plan's first customer is your own leadership.
The Value Edge Diagnostic
Thirty-two questions across four themes that place your business on a value maturity map. A mirror, not a report card.
The value ledger
The running record of value delivered: the evidence file every renewal needs and almost no account team can produce on demand.
The value maturity map
Organisational readiness against commercial performance: the summary grid the diagnostic's four themes roll up into.
The value proposition triangle
Future state at the apex, offer and assurance at the base, the proposition in the middle. A future state with no offer beneath it is a daydream.
Total cost of ownership
The whole burden of buying, running and living with a solution across its life. Used to change the subject from price before procurement raises it.
Value capture
Proving the value landed, in both directions: in the customer's KPIs and in your own board's numbers.
Value equals impact minus total cost of ownership
Value is what remains when you take the whole cost of having the solution from the impact the customer can bank.
Value selling
Selling the proposition twice: first inside your own company, then to the customer's decision-making unit in their financial language.
Value-in-use
The value a customer actually realises from what you sold them, measured after the sale, in their own numbers.
VUCA
Volatility, uncertainty, complexity, ambiguity: the US Army War College's description of the post-Cold War world, now the standing weather of business markets.
