Mota — Problem Definition¶

SDLC phase: Analysis / Chapter 1 (Introduction)
Document status: Approved for blueprint

1. Background¶

Zimbabwe's vehicle market has changed shape faster than its maintenance culture.

Between 2020 and 2025 the registered fleet grew 44.7% to 1.52 million vehicles — roughly 469,000 additional vehicles, with new monthly registrations now running at 10,000–11,000 (ZINARA). Licensing compliance is climbing toward one million vehicles. The fleet is dominated by used Japanese imports, which brings two structural consequences:

The service history does not survive the import. A vehicle leaves Japan with a service record, lands in Zimbabwe, and from that day forward its history is whatever the owner remembers and whatever is written in a paper booklet that lives in the glovebox.
Automatic and CVT transmissions are over-represented, and CVT fluid is the single most commonly deferred service on these vehicles. It is expensive, it is misunderstood, and the failure mode is a replacement gearbox rather than a repair.

At the same time, the repair sector is almost entirely micro-business. In Harare, ~155 car repair and maintenance businesses exist, and 94.19% are single-owner operations (Rentech Digital business census). These businesses keep customer records in their heads, on WhatsApp, or in a notebook. They cannot tell you which of their customers is due back for a service in eight months — and that is precisely the customer they most want.

So both sides of the market are missing the same thing: a persistent, portable record of what was done, when, and what's next.

2. The as-is experience¶

How a Harare car owner handles maintenance today. This is the process the product must beat — not another app.

Where it actually breaks¶

Step	Failure	Consequence
Awareness	No reminder exists. Nothing tells you the CVT fluid is due.	Service happens only after a symptom appears — i.e. after damage
Diagnosis	The owner has no reference price and cannot judge a quote	Overpaying, or choosing the cheapest quote and getting the worst job
Decision	No trustworthy signal about which garage is competent	Selection based on proximity and hearsay
Execution	No record is produced	The next owner, the next mechanic, and the resale buyer all start from zero
Aftermath	The cycle has no memory	The same mistake repeats on the same car

The critical observation: the failure isn't a lack of information at any single moment. It's a lack of persistence. Every step resets to zero. A notebook would fix half of this — which tells you the product's real job is not "provide information" but "maintain state across years, across owners, and across garages."

3. Cost of inaction¶

Quantifying the pain is what separates a real problem from an annoyance.

Failure	Typical cost	Frequency	Annual exposure
Deferred CVT fluid change → gearbox replacement	`[ESTIMATE]` US$800–2,500 for a reconditioned/replacement unit vs US$120–250 for the fluid service	Once per ownership if neglected	Up to US$2,500 per affected vehicle
Missed ZINARA licence renewal	Fine + re-registration friction + risk of impoundment	Annual	`[ESTIMATE]` US$50–150 in penalties and time
Lapsed insurance	Uninsured loss + re-instatement penalty	Annual	Catastrophic tail risk
No service history at resale	`[ESTIMATE]` 5–15% price discount on a used vehicle	Once per sale	On a US$8,000 car, US$400–1,200
Overpaying on unverified quotes	`[ESTIMATE]` 20–40% premium when the buyer has no reference price	Every repair	`[ESTIMATE]` US$100–400/year
Fill-up cost invisible	No km/l tracking means a failing engine or tyre pressure goes unnoticed	Continuous	Fuel waste, `[ESTIMATE]` 5–10%

[ESTIMATE] figures are order-of-magnitude placeholders to be validated in Stage Gate 0 interviews. They are included because a problem definition without magnitudes is just a complaint. They are not yet evidence.

The asymmetry that makes this sellable: the cost of the failure is high (US$800–2,500) while the cost of prevention is low (a free app, 20 seconds per log). That asymmetry is the entire value proposition, and it's what makes the product worth installing even with zero monetary incentive.

4. Problem statement¶

Zimbabwean vehicle owners have no persistent record of their vehicle's maintenance history and no reliable way to know what service is due, when, or at what price. This causes preventable mechanical failures that cost multiples of the service they replace, destroys resale value, and leaves owners unable to distinguish a fair quote from an exploitative one. On the supply side, the small independent garages that perform the work have no customer records and no way to predict when a customer is due to return — so both sides lose the value of a continuing relationship.

5. Aim¶

Build a free, offline-tolerant Android application that maintains a vehicle's service history and deadline state, tells the owner what is due before it fails, and converts that moment of high intent into a paid connection to a vetted garage.

6. Objectives (SMART)¶

Each objective is numerically falsifiable. An objective that cannot fail is not an objective.

#	Objective	Measure	Target	Deadline
O1	Recruit and retain real users	Activated users (1 vehicle + 1 event logged)	300	Day 90
O2	Prove the product is used, not just installed	30-day retention (any return action)	≥25%	Day 90
O3	Prove the deadline engine is trusted	Reminder open/acknowledge rate	≥40%	Day 120
O4	Prove supply-side value	Partner garages with ≥1 attributed booking	8	Day 120
O5	Prove willingness to pay	Paying garages (not free tier)	5	Day 180
O6	Prove unit economics	Monthly recurring revenue	US$300	Day 180
O7	Prove the price index is useful	Price-index views per active user per month	≥1.5	Day 180
O8	Establish a defensible dataset	Unique vehicle-service records in database	5,000	Day 365

Non-objectives for year 1: iOS, hardware integration, marketplace checkout, expansion beyond Harare. Explicitly out so they don't consume capacity.

7. Constraints¶

Hard constraints (cannot be engineered around)¶

#	Constraint	Implication
K1	Solo / 1–2 builder capacity	Every feature must justify its maintenance cost. No microservices, no custom infrastructure.
K2	Near-zero capital	Infrastructure budget ≤US$50/month until revenue. No paid acquisition. No hardware.
K3	Android-dominant, low-end devices	US$60–120 phones, 2–3GB RAM. PWA or lightweight native. Performance budget is a hard requirement, not a nicety.
K4	Metered, unreliable data	Offline-first writes, <500KB per session, no polling.
K5	Consumers will not pay	Revenue must come from the supply side. Any model requiring consumer payment is rejected.
K6	Cyber & Data Protection Act 2021	POTRAZ data controller registration; lawful basis; data-subject rights; cross-border transfer restrictions.
K7	Cash-heavy informal supply side	Billing must accommodate cash, WhatsApp, and mobile money — not just cards.

Assumptions (believed true, not yet verified)¶

#	Assumption	How it gets tested	If false
A1	Owners will log a fill-up in <30 seconds if the UI is fast enough	Gate 0 usability test, 10 users	Product needs passive capture (OBD/manual photo) or the retention model collapses
A2	Garages will pay US$2–5 per attributed booking	Gate 2: charge 3 founding garages	Model shifts to subscription-only or sponsored parts. Now supported by analogy: ZWPRICE operates a supplier-paid, buyer-free RFQ marketplace across 26 Zimbabwean supplier brands. Suppliers do pay to receive qualified buyers in this market.
A3	A PDF service record is valuable enough to be shared	Measure PDF export and share events	Drop from v1, replace with a simpler share card
A4	Owners know their current odometer reading	Gate 0 interviews	Add an odometer-estimation nudge, or ask only at service events
A5	Car WhatsApp groups are a viable distribution channel	Gate 0: post in 5 groups, measure signups	Pivot to garage-led acquisition (garage signs up its own customers)

8. Justification¶

Why now¶

The fleet just crossed an inflection point. 1.52M vehicles and 120k+ additions per year means the population that needs this is growing faster than any solution is being built for it.
Payment and connectivity infrastructure is finally adequate. 84.55% internet penetration and universal mobile money (EcoCash ~86% share) mean a free app with a paid garage back-end is operationally possible today in a way it wasn't in 2019.
The incumbent distraction has passed. The market's attention was consumed by load-shedding for years. That crisis has eased, and attention is available for the next tier of everyday problems.

Why us¶

The founder owns the exact problem: a Nissan Note with a CVT, in Harare, with no service history and no reliable way to know what's due. This is not market research — it is lived experience, which is the highest-quality input available at pre-product stage. It means the details will be right: the specific anxiety of a CVT noise, the specific way a Harare mechanic quotes a job, the specific reason a paper service book gets lost.

Why this and not the other four ideas¶

See 01-ranking.md. In short: it is the only idea that scores well on pain, market, monetisation, competition, buildability, and distribution simultaneously. The alternatives are either unwinnable (ZESA app against the incumbent), unbuildable solo (kombi tracking), undifferentiated (household manager against free global apps), or already occupied (grocery price comparison).

9. Conclusion¶

The problem is not that Zimbabwean drivers lack information. It is that they lack persistence — a record that survives the glovebox, the mechanic, and the resale. Everything else (reminders, price transparency, garage discovery) is a downstream consequence of holding that record.

That's the wedge. If the product can't hold a trustworthy record, no amount of garage marketplace will save it. If it can, it becomes the only place where a Harare vehicle's history actually lives — and that's a defensible position.
