What is Product Development Strategy?
Product development sells new products to the firm's existing customer base. Sub-strategies: line extension (more flavors, sizes, formats of existing brand), new product category (a different category sold to the same customer), and incremental innovation (next-generation versions of existing products). The strategy leverages existing customer relationships, brand equity, and channels — reducing sales risk — while introducing development risk on the product side. The classic discipline is "stay close to the existing customer" — develop what they want, not what the firm finds interesting.
How Product Development Strategy actually works
The framework breaks down into the following moving parts. Knowing what each piece is — and what it is not — is what separates a B-grade answer from an A-grade answer in a written assignment.
- Line extension — flavors, sizes, formats
- New category in existing customer base
- Next-generation upgrades
- Use existing customer research to prioritize
- Leverage existing brand and channels
A worked example: Apple
Apple's product development discipline is legendary. iPod (2001) sold to Mac users; iPhone (2007) sold to iPod users; iPad (2010) sold to iPhone users; Apple Watch (2015) sold to iPhone users; AirPods (2016) sold to iPhone users; Apple TV+ and Apple One (2019–) sold to the device base. Each product extended the offering to the existing customer base before opening to new customers. The strategy exploited Apple's deep customer relationship and brand permission — and grew revenue from $5B in 2001 to $383B in 2023.
Don't lose marks for these
- Developing what management finds interesting, not what customers want
- Cannibalizing existing products without growing total category
- Stretching the brand into categories where the existing customer has no permission
How to use this on the exam
Score-maximizing moves
- Distinguish line extension, category extension, and innovation
- Reference brand permission and stretch
- Cite Apple as canonical example
When to use Product Development Strategy (and when not to)
Use Product Development Strategy when your assignment asks you to analyze, structure, or recommend — and when you have at least two data points to populate every cell of the framework. Skip it when the question is asking for a numerical answer or a single recommendation, since Product Development Strategy is a structuring tool, not a calculator.
