When I buy something meant to last, I want to choose the durable one, so I am not buying three times in the span of one.

Job context

Who

Someone buying goods meant to last

When

When the old one has just broken

Trigger

Something failing just after the warranty ends

Situation

Two similar items differ in lifespan by years

Constraints

No durability information exists at the moment of buying

5 Pains

• No durability information anywhere

  High

  The specifications say nothing about lifespan.

  Root cause: Nobody measures and publishes how long a product lasts

• A higher price guarantees nothing

  High

  Often it is only the brand.

  Root cause: Price reflects many things besides quality

• Reviews are written right after purchase

  High

  So they say nothing about durability.

  Root cause: Platforms request reviews days after delivery

• Repair costs nearly as much as replacement

  Medium

  So it is almost always discarded.

  Root cause: Products are designed for fast assembly rather than for repair

• Spare parts cannot be found

  Medium

  Gone after a few years.

  Root cause: Manufacturers stop supplying parts for older lines

5 Desired Outcomes

• Know which item lasts longer

  Functional

• Know whether a higher price is matched by anything

  Functional

• Read reviews written years into use

  Functional

• Repair it at a sensible cost

  Functional

• Find parts when needed

  Functional

5 Existing Solutions

A solution is not the same thing as a product, a customer can hire a behaviour or a workaround too.

• Choose a known brand

  Behaviour

  The only remaining heuristic, resting on products from years ago.

• Read in-depth review sites

  Product

  The best source available, mostly testing for a few weeks.

• Ask someone who has used it for years

  Behaviour

  The only source that speaks to durability, covering very few products.

• Choose a long warranty

  Product

  The closest signal of a maker's confidence, and also a product being sold.

• Buy cheap and replace often

  Workaround

  A rational strategy in the absence of information, and more expensive over time.

2 Opportunity Gaps

• Reviews are collected right after delivery while durability information exists only after years, and no mechanism bridges the gap.

  Why existing solutions fail: Platforms ask early because that is when response rates are highest, and after three years the buyer has no reason to return and write, so the entire review corpus of online retail describes first impressions rather than quality.

  Potential opportunity: Asking buyers again at two and five years, and displaying those answers separately.

• Products are compared by price and specifications because both are available at purchase, while what determines the real cost is lifespan, which appears nowhere.

  Why existing solutions fail: Publishing lifespan exposes a product to direct comparison on the very dimension most makers would lose on, and it slows repeat purchases, so nobody in the trade has a reason to go first.

  Potential opportunity: Lifespan derived from real repair and warranty data, published by a party outside the trade.
