Today, we will explore a structured way to implement IoT projects called the 3-Question Approach (W-W-H). This approach revolves around asking three key questions: What? Why? How?
Let’s review each step to understand how this framework ensures clarity and direction for IoT solutions.
1. What? (Problem Statement)
The first question is What? which helps us identify the problem we’re trying to solve.
Purpose: To uncover the actual pain points or gaps in current processes.
Steps:
- Look for inefficiencies or challenges in operations.
- Identify areas where IoT can provide value.
Examples:
- Low production rates in a factory.
- Increasing operational costs.
- Poor quality control leads to defects.
- Safety incidents in a workplace.
- Intermittent services in logistics or delivery.
Understanding the problem is the foundation of any successful IoT project.
2. Why? (Objective & End Goal)
Next, we ask Why?, which focuses on the objective and the end goal of the IoT implementation.
Purpose: Clearly define what you want to achieve and align everyone toward that goal.
Steps:
- Get buy-in from stakeholders by explaining the benefits.
- Ensure the outcome can be monitored and measured effectively.
Examples of Objectives:
- Improve logistics and delivery efficiency.
- Reduce operational costs.
- Enhance asset utilisation and reduce errors.
- Boost overall safety and performance.
Defining the “why” ensures a clear purpose behind the IoT deployment.
3. How? (Solutions)
The final question is How? which focuses on the solutions to address the problem and achieve the goals.
Steps:
Use the DNA approach:
- D — Device: Identify the right sensors to collect the required data.
- N — Network: Choose a suitable network for connectivity (e.g., Wi-Fi, LoRa, 5G).
- A — Applications: Develop platforms (mobile or web) to process and display the data.
- Decide on an implementation strategy:
- Build in-house.
- Operate internally.
- Outsource to a third party.
- Collaborate with partners.
Examples of Solutions:
- Install sensors to monitor production lines in real time.
- Ensure the network has sufficient coverage and can handle the amount of data.
- Develop mobile or web applications to provide actionable insights.
The “how” ensures the project is feasible and actionable.
Key Takeaway
The 3-Question Approach provides a clear path for implementing IoT solutions:
- What? — Define the problem.
- Why? — Establish the objective.
- How? — Develop the solution.
This framework ensures every IoT project is focused, aligned, and effective. Think big, but start small.
