How many good ideas have come out of your sales and marketing meetings, only to go nowhere? A promising concept for a new campaign or a fresh sales approach gets discussed, but it either fizzles out or gets launched with a great deal of guesswork, and ultimately falls flat.

Stop Guessing, Start Testing: A Practical Guide to Design Thinking

Having ideas is easy. The real challenge is turning those ideas into measurable results. This is where many businesses struggle; they lack a structured process for testing, refining, and validating their ideas before investing heavily in them.


Design thinking provides that process. It’s a practical framework that helps you move from "I think this will work" to "I know this works because we've tested it."


The Problem with the 'Launch and Hope' Approach


Too often, sales and marketing strategies are based on internal assumptions. A team comes up with what they believe is a brilliant idea, invests a lot of time and money building it, and launches it to the entire market, hoping for the best. When it doesn't work, it's a costly failure.


Design thinking flips this model on its head. It’s a human-centred approach that encourages you to test and learn in small, fast cycles, reducing risk and greatly improving your chances of success.


A Simple Way to Test Your Ideas


Imagine your marketing team wants to launch a new email campaign to 100,000 people.


  • The risky 'launch and hope' approach: They spend two weeks perfecting one version of the email, send it to everyone, and hope for a good open rate.


  • The design thinking approach: They use a simple, five-step process:


    1. Empathise: They talk to a few customers to understand what kind of emails they actually find useful and what makes them open one.


    2. Define: They define the problem as: "Our customers are busy and ignore most marketing emails. We need a subject line that is both interesting and clearly communicates value."


    3. Ideate: They brainstorm five different, creative subject lines.


    4. Prototype: The "prototype" is simply the five different versions of the email.


    5. Test: They send each version to a small test group of just 100 people each. They analyse the results to see which subject line gets the best open rate.


Now, they can launch the winning version to the remaining 99,500 people with a much higher degree of confidence that it will be successful. This is the core of design thinking: small, fast experiments that lead to better results.


A Practical Guide to Using This Process


You can apply this thinking to almost any sales or marketing challenge.


  1. Start with the Customer, Not Your IdeaBefore you brainstorm solutions, make sure you deeply understand the problem you are solving. This means talking to your customers and listening to their challenges.


  2. Brainstorm Many OptionsDon't fall in love with your first idea. Encourage your team to come up with a wide range of possibilities. The best solution often comes from combining elements of several different ideas.


  3. Build a Simple PrototypeA prototype doesn't have to be complicated or expensive. It can be a sketch of a new webpage, a draft of a new sales script, or a mock-up of a new advert. The goal is to make your idea tangible enough so that you can get real feedback on it.


  4. Test and Listen to FeedbackShow your prototype to real customers. Watch how they interact with it. Listen to their feedback, both positive and negative. Be prepared to change your idea based on what you learn. The purpose of testing isn't to prove you were right; it's to find the best possible solution.


Learning to Apply This Method in Your Business


Adopting this structured, experimental approach requires a shift in mindset for many teams. It’s about being comfortable with not having all the answers upfront and being willing to learn through doing.


Developing these skills is the core focus of the Design Thinking for Sales and Marketing Innovation (DTSM) course at ClickAcademy Asia.
