How to Hire a Product Design Firm

What can product designers do for businesses?

At a strategic level, they help businesses decide what to build, for whom, and how to make it easier to adopt, buy, and use.

Customer-centered companies consistently outperform weaker competitors.

Namely, in Forrester's 2024 US Customer Experience Index, customer-focused organizations reported 41% faster revenue growth, 49% faster profit growth, and 51% better customer retention than less customer-focused peers.

In practice, that means good product design can influence growth, loyalty, and margin, rather than just aesthetics.

Product design agencies help companies move from ideas to outcomes more efficiently.

IBM reports that organizations see an average ROI of 46% on new digital product creation and 75% on enhancements to existing digital products.

For many businesses, the biggest value of a strong product designer is risk reduction.

Product design companies turn vague ideas into tested concepts, clarify user needs, and catch problems before a company invests too heavily in development or manufacturing.

McKinsey found that around 50% of surveyed companies conducted user research before generating their first design ideas or specifications, which suggests many businesses still move too quickly into execution without enough evidence.

Product design firms also help businesses improve commercial performance.

In digital environments, even minor experience issues can translate into lost sales, lower conversion rates, and weaker retention.

Baymard's 2025 compilation of checkout studies found an average documented cart abandonment rate of 70.22%, which shows how much revenue can disappear when journeys are confusing.

In industrial design, agencies shape usability, manufacturability, and perceived value.

PwC's 2024 Voice of the Consumer Survey found that consumers are willing to pay an average of9.7% premium for sustainably produced or sourced goods.

What does a typical product design process look like?

Leading product design studios follow a user-centered and data-driven approach, combining UX research, engineering, and design into one continuous workflow.

According to McKinsey, companies that integrate design into their processes outperform competitors with 32% higher revenue growth and 56% higher shareholder returns, highlighting the direct business value of a well-executed design process.

1. Discovery and research

Teams conduct research, competitor analysis, and stakeholder interviews to define clear product goals. This stage ensures the business is solving the right problem before investing in development. CB Insights reports that 35% of startups fail due to the lack of market need, which strong discovery work helps prevent.

2. Definition and strategy

A product design agency defines target users, use cases, core features, product scope, success metrics, and business objectives.

At this stage, designers align design decisions with business goals, ensuring the product supports growth, rather than just usability.

3. Ideation and concept development

During this phase, design teams brainstorm, concept sketch, create wireframes and early prototypes, and explore different UX/UI directions before committing to one. Product design companies typically test several concepts before narrowing down to the most viable solution.

4. UX/UI and detailed design

This phase turns a rough idea into a complete, detailed blueprint that developers or manufacturers can actually build.

For digital products, during this phase, experts design exactly how the product looks and works for users.

It includes:

• Designing what users see
• Defining how users move through the product
• Creating layouts for a mobile app or web design
• Building a consistent system of buttons, colors, and styles

For physical products, during this phase, product designers define how the product looks and how it will be manufactured.

It includes:

• Shaping the product (size, form, ergonomics) through industrial design
• Choosing materials (plastic, metal, etc.)
• Creating precise 3D models using CAD modeling so designers can manufacture the products
•  

5. Prototyping and testing

Teams create interactive or physical prototypes and test them with users. Iteration is key, and fixing issues early is critical, as defects can cost up to 100× more to fix after launch, according to IBM. This stage ensures the product works in real-world conditions.

6. Engineering and development collaboration

Design is translated into a build-ready solution. During this step, product design agencies ensure the final product matches the design vision while remaining technically viable.

7. Launch and optimization

After release, the process continues with improvement and scaling. Designers monitor user behavior and engagement, performance metrics, and feedback and usability issues.

Google research shows that companies running continuous experimentation can improve key metrics by 10-30% over time.

What red flags should I watch for when evaluating these firms?

Watch for the following warning signs when you start evaluating product design companies:

1. No clear design process: The agency cannot explain how it moves from research to final product, which increases risk and delays.
2. No measurable results in portfolio: Case studies show visuals but no data, such as conversion rates, user engagement, or business impact.
3. Lack of UX research: They skip UX research and jump straight into design without validating user needs, which can be a major cause of product failure.
4. Vague scope and pricing: Unclear deliverables, timelines, or revision limits often lead to hidden costs and budget overruns.
5. Weak technical or engineering expertise: Product designers have no evidence of feasibility work like CAD modeling, mechanical engineering, or development handoff.
6. No relevant industry or product experience: Little experience with your type of product can slow progress and increase risk.
7. Poor communication and collaboration: Slow responses, no clear point of contact, or lack of a collaborative approach early on.
8. No post-launch support: The agency does not offer ongoing optimization, even though modern digital products require continuous improvement.
