The 5 Ws and H: who, what, when, where, why, and how

Who is experiencing the problem? Knowing your users and their background is key to creating successful solutions for them.
What are the pain points you’re trying to solve? Determining a user’s pain points early allows you to answer the rest of these questions and clarify the context of the pain points.
Where is the user when they’re using the product? A user’s physical context matters to your design.
When does the problem occur? Maybe it’s right after the end of a long and tedious process, or maybe it’s something that happens daily. Knowing when the problem occurs can help you better empathize with the user’s feelings.
Why is the problem important? Knowing how this problem affects your user’s experience and life will help to clarify the potential consequences.
How are users reaching their goals by using the product? Understanding how users reach their goals allows you to map the user journey that they take through your product.

The problem statement formula

With these parts clearly defined, the problem statement is:

  • Human-centered and focused on the needs of a specific type of user.
  • Broad enough for creative freedom.
  • Narrow enough to be solved by a practical design solution.

Example:Dog walker app

  • Who: A busy executive
  • What: Arnold wants to hire a daily dog walker for his three dogs.
  • Where: Arnold is likely using the app at work, on the go.
  • When: Arnold gets frustrated when he opens the app, starting from the very beginning of the user journey.
  • Why: Arnold doesn’t have a lot of experience with phone apps or similar technology.
  • How: Arnold wants to go easily from the home screen of the app to the list of dog walkers to the confirmation screen.

Value proposistion

Value propositions summarize why a consumer should use a product or service.

To answer these two questions:

  • What does your product do? Clearly explain the offering that your product provides users.
  • Why should the user care? Describe how your product addresses users’ pain points.

Steps

Step 1. Describe your product’s features and benefits.
Create a list of all the great features and benefits of your product, big and small. Don’t hold back; list everything that comes to mind and then narrow it down later.

Step 2. Explain the value of the product.
Anything that you identify as a value proposition needs to be beneficial to your users. In this example, for the dog walker app, there were four categories of product values that were identified during user interviews: accessible, professional experience of the dog walkers, cost, and reliability. The giant list of features and benefits from step one is sorted into those four categories.

Step 3. Connect these features and benefits with the needs of your users.
You’ve narrowed your list down of lots of benefits and features by matching them with actual user needs. Now it’s time to review the list of value propositions your product offers. For the dog walker app, here are the value propositions that matched with the personas that were developed earlier:

  • Thorough training for walkers
  • Upgrade dog walkers to dog nanny for set, scheduled walks
  • Geo-tracking of walkers
  • Calendar booking
  • Late-notice cancellation fees
  • Convenient lockers that hold your house keys
  • Easy-to-use app design

And there you have it, your list of value propositions! However, some of these features and benefits are also offered by your competitors. So how do you know what makes your product stand out from the competition? Identify your app’s unique value proposition. This means reviewing the list of value propositions that match to your personas and removing those that your competition also offers.

Key takeaways

One of the most important things to know about value propositions is that they need to be short, clear, and to the point. Users want to be able to easily identify exactly how your product will meet their unique needs and what sets your product apart in the market. Sometimes users won’t know what they need until you explain it to them. That’s the real heart of product design innovation.
