## Required Inputs

| Input | Required | Use |
|---|---|---|
| Decision, audience, and deliverable | yes | Bound the business outcome |
| Source evidence, constraints, and owner | yes | Ground recommendations and accountability |
| Approved budget, customer data, or production artefacts | conditional | Support high-impact execution |

## Capability and permission contract

Default to read-only analysis and drafting. Do not publish, send, price, promise, alter customer records, commit budget, or modify production artefacts without explicit authority and a named approver. Minimise confidential data, preserve provenance, and keep reversible copies.

## Degraded mode

If evidence, stakeholder decisions, specialist tooling, or authoritative commercial data are unavailable, deliver a labelled draft, checklist, or decision memo. State what was not verified and do not claim approval, publication, financial accuracy, or customer acceptance.

## Decision rules

| Condition | Action | Stop condition |
|---|---|---|
| Output creates a commercial, customer, or delivery commitment | Obtain named approval before release | Authority or terms are unclear |
| Evidence supports a reversible draft | Produce it with assumptions and owner | Required evidence conflicts |
| Tooling or data is incomplete | Specify validation | A final executable artefact is expected |

## Domain Anti-Patterns

- Inventing customer evidence, prices, benchmarks, or approvals. Fix: cite the source or mark the gap.
- Publishing or sending a draft without authority. Fix: retain draft status and name the approver.
- Hiding assumptions inside polished prose. Fix: expose them beside each affected decision.
- Polishing presentation while the decision remains unclear. Fix: resolve audience, owner, and acceptance criteria.
- Treating unavailable tooling as passed validation. Fix: record the unassessed check.

## 1. The Three Business Models

Every software company sits somewhere on a spectrum between two extremes, or tries to occupy
a hybrid position.

### Model A — Pure Products

Sell software licences or subscriptions with minimal human services involvement.

**Characteristics:**
- Revenue is recurring and scalable; marginal cost per additional customer is near zero.
- High upfront investment in R&D; long payback period.
- Success requires large markets and strong distribution.
- Gross margins: 70–90%.

**When it works:** When the problem is common enough that one solution serves thousands of
customers with minimal customisation; when distribution can scale without proportionally
scaling headcount.

**Examples:** Microsoft Office, Salesforce CRM (standard tiers), Slack, GitHub.

**Risks:** Competition can commoditise the product; without services, customer success is
entirely dependent on product quality. Churn is invisible until the renewal conversation.

### Model B — Pure Services

Deliver value through human expertise: custom development, consulting, integration, managed services.

**Characteristics:**
- Revenue scales linearly with headcount; gross margins 20–40%.
- Lower risk than products — you are paid before you build.
- Highly cash-generative in early stages.
- Ceiling: headcount limits growth; difficult to scale without sacrificing quality.

**When it works:** When each customer's problem is sufficiently unique to require bespoke work;
when relationships and domain expertise are the primary value (not replicable code).

**Examples:** Custom software houses, IT consultancies, system integrators, implementation partners.

**Risks:** Revenue is non-recurring; key-person dependency; no compounding advantage over time.

### Model C — Hybrid (Products + Services)

Combine a software product with services that accelerate adoption, customise the product, or
extend its value.

**Characteristics:**
- Product provides recurring revenue floor; services provide growth revenue ceiling.
- Gross margins: 50–70% blended.
- Services can fund product R&D in early stages.
- Risk: Services can cannibalise product investment if not actively managed.

**When it works:** For enterprise software where standardised software meets 80% of need and
services fill the remaining 20%; when implementation complexity requires expert guidance.

**Examples:** SAP, Oracle, Workday (product + implementation services), Salesforce + consulting
partners, most African enterprise software companies.

## 2. The Services-to-Products Transition

The most dangerous and most valuable journey in software business is transitioning from a
services company to a products company.

### Why It Is Attractive

- Products scale without proportional headcount growth.
- Recurring revenue is more predictable and more valuable at acquisition.
- Product IP is defensible; services expertise walks out the door.

### Why It Is Hard

- Services revenue pays salaries now; product revenue pays future salaries.
- The incentive is to take every services engagement, even those that compete with product investment.
- Services customers want customisation; products require standardisation. These forces are opposed.

### Cusumano's Transition Framework

1. **Identify the repeatable core.** Look for the service you deliver repeatedly with the same
   approach. That pattern is the product kernel.
2. **Build the product alongside services, not instead of services.**
   Use services revenue to fund product R&D. Do not cut services before the product generates
   comparable revenue.
3. **Set a explicit product revenue target.** "When product revenue reaches 40% of total revenue,
   we begin to decline new bespoke services engagements."
4. **Create separation.** Separate the services team from the product team to prevent services
   pressure from reshaping the product roadmap.
5. **Sign reference customers on the product.** Get 3–5 customers to use the standardised product
   before building more custom features. Their success stories are the proof the market needs.

## 3. Platform Business Models

A platform creates value by facilitating interactions between two or more distinct user groups
(producers and consumers). The platform does not own the value created — it enables it.

### Two-Sided Platform Mechanics

- **Network effects:** Each additional participant increases the platform's value for all
  participants. Facebook is worthless with 10 users; invaluable with 1 billion.
- **Cross-side network effects:** More sellers attract more buyers; more buyers attract more sellers.
- **Same-side network effects:** More developers on a platform makes it more attractive to other
  developers (more libraries, tools, and shared knowledge).

### The Cold Start Problem

A platform with no participants on either side has zero value. Strategies to solve it:

- **Seed one side:** Acquire sellers/producers with subsidies, partnerships, or direct recruitment
  before launching to buyers/consumers.
- **Single-player mode:** Design the product so it delivers value to one user before the network
  exists. Dropbox was valuable to a single user (storage) before it had any network effect (sharing).
- **Constrained launch:** Launch in a single city, university, or industry vertical. Build density
  before breadth.

### Platform Governance

Once a platform reaches scale, governance becomes the hardest problem:
- Who is allowed to participate?
- What can participants build or sell on the platform?
- How are disputes between participants resolved?
- How does the platform extract revenue without undermining participant trust?

*A platform that extracts too much revenue from its ecosystem destroys the ecosystem that
makes it valuable. See Apple/Epic, Amazon Marketplace, and Google Play controversies.*

## 4. Licensing Models

### Perpetual Licence

Customer pays once for the right to use the software version purchased. Optional annual
maintenance fee (typically 18–22% of licence price) for updates and support.

**Pros:** Large upfront cash inflows; customers feel ownership.
**Cons:** Revenue is lumpy and non-recurring; customers stay on old versions to avoid upgrade costs;
support burden grows as version fragmentation increases.

*Perpetual licences are declining. Most software companies have migrated or are migrating to
subscription models.*

### Subscription

Customer pays a recurring fee (monthly or annual) for access to the latest version plus support.

**Pros:** Predictable recurring revenue; customers are always on the latest version; natural
customer success touchpoints at renewal.
**Cons:** Customers can cancel at any time; cash flow ramps slowly compared to perpetual upfront payments.

**Rule:** Annual subscriptions paid upfront are strongly preferable to monthly subscriptions.
They reduce churn, improve cash flow, and increase LTV:CAC ratios.

---

## 5. Open Source Strategies

Open source is a go-to-market strategy, not a charitable act.

### Open Core Model

The core product is open source (free, community-maintained). Advanced features — enterprise
authentication, compliance tools, admin controls, SLA support — are proprietary and paid.

**Examples:** GitLab, HashiCorp Vault, Elasticsearch (before Elastic re-licenced), MongoDB Community.

**Why it works:** The open source core builds trust, community, and distribution at near-zero
marketing cost. Enterprise features monetise the segment that can pay.

**Risk:** The boundary between open core and proprietary features must be drawn carefully.
Too little open source and the community does not form. Too much open source and there is
nothing to sell.

### Open Source as Distribution

Release the product freely to build adoption, then monetise with hosting, support, or enterprise
services. The product itself is the marketing.

**Examples:** Linux (Red Hat), WordPress (Automattic/WP Engine), Android (Google services).

### When NOT to Open Source

- Your competitive advantage is the code itself (not the distribution or the brand).
- You have not yet found product/market fit — open sourcing before validation disperses attention.
- Your team cannot manage a community in addition to product development.

## 6. Startup Survival Patterns

From Cusumano's analysis of software startup outcomes:

### The 5 Essential Elements of a Software Startup

1. **Founders who understand both technology and business.** Pure technologists build great
   demos; pure business people build great decks. You need both in the founding team.

2. **A product that solves a real, painful problem.** Not a problem the founders find interesting —
   a problem a specific set of customers would pay to solve today.

3. **A go-to-market motion that matches the product.** Enterprise software requires direct sales.
   Consumer software requires viral growth or performance marketing. The wrong motion burns runway
   without traction.

4. **Unit economics that work at scale.** A business that loses money on every customer does not
   become profitable at volume — it loses money faster. Validate unit economics at 100 customers,
   not 10,000.

5. **A business model that generates recurring revenue.** One-off project revenue is a consulting
   business. A scalable software company needs recurring, compounding revenue.

### The Cash Flow Trap

Services revenue is cash-generative now. Product revenue is cash-generative later. Many software
companies delay the product transition because services cover payroll. The correct response:

- Set a 3-year product revenue target with quarterly milestones.
- Ring-fence a product development team that is not pulled into services engagements.
- Raise external capital if necessary to fund the transition without starving the product.

## 7. Choosing Your Business Model

Use this decision framework:

```
1. Is your solution standardisable?
   → Yes: Products or Hybrid
   → No (each customer is unique): Services

2. How large is your target market?
   → Large (> 1,000 potential customers with similar problems): Products or SaaS
   → Small or niche (< 100 customers, high willingness to pay): Services or Hybrid

3. What are your capital constraints?
   → Low capital, need early revenue: Services first, product over time
   → External capital available: Product from day one

4. What is your competitive moat?
   → Code and data: Products
   → Network effects: Platform
   → Domain expertise and relationships: Services or Hybrid
   → Distribution: Open Source as distribution tool
```

## Quality Standards

The recommended model must reconcile payer, value exchange, revenue timing, delivery cost, channel incentives, transition burden, and a falsifiable adoption assumption.
