Agile methodology for IoT product development

If you’ve read our IoT basics series, you know exactly what an IoT device is. You know how to manage these devices. We also know how to design, build and deploy IoT products. All that remains is to put everything together. It starts with a strategic framework for IoT development. In other words, to bring an IoT project from scratch to market, you need to know what to do and in what order. Here we explain how Agile methodologies work as a framework for product development.

Most software development strategies derive from two main methodologies: waterfall and Agile. The waterfall model organizes the development process into a series of steps with distinct phases and dependencies. First, gather your requirements. Then make a plan. Design, develop, test, and finally deploy one product after another without deviation.

This tidy system lends itself well to static hardware development. After all, you can’t replace the plastic once it leaves the extruder.

But waterfall development does not support the iterative growth that leads to great IoT products. To do that, we need to take advantage of agile methodologies that provide a proven framework for building IoT systems.

Understand agile methodologies for IoT products

Against the rigidness of waterfall development, a group of innovative software developers Agile manifesto in 2001.

This formative document leaves out many details. Instead, it provides a list that prioritizes some elements of software development practice over others. Here is the full Agile Manifesto (reprinted with permission of the Agile Alliance):

Agile manifesto We are discovering better ways to develop software by developing it and helping others do it. Through this initiative, we have come to value the following: – Individuals and Interactions Beyond processes and tools – Software that works than comprehensive documentation – Customer collaboration Regarding contract negotiations – Response to change more than following a plan In other words, the items on the right have value, but We give more weight to items on the left.

So how does this simple priority list translate into a highly effective IoT product development process?

• the taste of Individuals and Interactions This enables collaborative processes where cross-functional teams and decision makers work together without silos.

• the taste of Software that works Break development into iterative loops instead of one rigid step-by-step process. Each development cycle ends as follows: minimal utilitarian product Or MVP. Iterating on these MVPs will incrementally improve your product until you scale up production and with each subsequent cycle.

• the taste of Customer collaboration represents the ideal relationship between you and your IoT development partner. If IoT developers follow the Agile model, they will prioritize strategic problem-solving, extreme integrity, and effective teamwork.

• the taste of adapt to change Developers should constantly evaluate and improve their products. This is achieved through rigorous de-risking, prototyping and testing, including regular post-launch customer feedback.

While there is considerable variation in how organizations implement Agile methodologies, each stage of the Agile IoT development process typically takes between one and four weeks. During this period, team members complete defined tasks and communicate in daily stand-up his meetings and in-depth planning sessions at the beginning of each period.These stages are called sprint.

Most IoT development sprints consist of nine major steps:

1. Advance planning: Validate assumptions and identify constraints (budgets, staffing levels, time limits, etc.).
2. plan: Create a product development roadmap (details below).
3. Hardware de-risking: Make sure your hardware can perform all your mission-critical tasks.
4. imitative prototyping: A development board and basic software are used to create a rough prototype that can mimic the expected performance of the finished product.
5. Full prototyping: Create prototypes that can send and receive data in real-world scenarios.
6. In-house production: Create a near-perfect version of your product for initial testing using custom printed circuit boards and 3D printed components.
7. Beta test manufacturing run: The first production will produce about 100 devices. We will distribute these to our beta testers and fix them as they arise.
8. Early adopter manufacturing execution: Once we are satisfied with the first 100 devices, we will scale up to produce about 1,000 products for early adopters. Please continue to collect feedback and make improvements.
9. Full production: At this point, the product is ready to go to market with the first full manufacturing run.

At the end of each production step, create an MVP that proves the value of your project. However, the product evolves out of the MVP realm and reaches maturity as you start adding features. It then moves on to larger manufacturing processes, continuing to iterate and improve at each step.

However, these development Sprints are only effective if you define clear project goals from the beginning. That’s why we encourage you to start a partnership with an IoT developer. technical design sprint.

Technical Design Sprint: Starting the IoT Development Process

Technical design sprints help IoT developers deepen their understanding of the project. These clarify business needs, end-user behavior, and the proposed value of IoT products. With these elements clearly defined, IoT developers can create an overall plan for subsequent development sprints.

The final result of the technical design sprint is Step-by-step product roadmap, a sort of guide to progressive MVPs that start delivering value as soon as possible. Once this phase of the development process is complete, some concrete plans will be created. These include:

1. Product development roadmap

A roadmap describes the solution you are about to build with the goal of proving the business case. Elements of the IoT product roadmap include:

• The customer problem your product solves
• User identities and expected behaviors, including both standard end-users and system administrators
• The ideal customer journey for product users
• Features you want to provide (prioritized according to importance)
• Clear and honest description of project risks, constraints and potential bottlenecks

A completed roadmap provides very specific, technical and organizational goals for each task you want your product to support. This defines the progressive releases we create in each development sprint. In other words, it provides a clear plan for the entire development process. However, to create the most successful roadmap, you should also define the rest of this list.

2. Technical Engineering Details

Here, IoT development partners define the system architecture, integration, and technology stack for the system they build together. They also help define key technical requirements such as security, scalability, and connectivity needs.

3. Workflow map

End users can interact with the product through several interfaces, from cloud platforms to device screens. Workflow Her maps visually project how these interfaces work. Easy-to-understand workflow charts guide you through options, consequences, errors, and paths to error resolution.

These workflow maps guide software developers as they build these interfaces, improving them with each development cycle.

4. Use cases

The more you understand how users interact with your solution, the more value you can bring to your project. Developers can help define possible use cases, such as user motivations, how the feature helps them achieve their goals, and the desired outcome for each example.These use cases are called work story.

Once you and your partner have defined as many job stories as possible, you can prioritize the job stories based on the value they provide. This prioritized list indicates which features to build first and helps you estimate the risks and costs associated with building each product feature.

The Role of Development Partners in IoT Products

A technical design sprint creates all of these organizational items and guides each iteration of development sprints to a rapid and successful market release. However, as you can see from this four-part series on IoT basics, building an IoT product yourself isn’t always easy.

Fortunately, an IoT development company can help. (Be sure to choose her IoT developer who follows the Agile methodologies above.)
