Why No One-Size-Fits-All Method Works: Crafting Custom Software Development Processes

21st Century Tech Officer's guide: From the initial idea to implementation, the best overall software approach rarely is one‑size‑fits‑all.

I have worked in software project management for nearly twenty years; as a consultant I often field questions about the best software development method, and this is a concise version of my usual answer.

No silver bullet exists

The first thing to understand is that no single method fits every possible project.

Each project is a complex problem, and different variables may require different approaches, even for seemingly similar challenges.

For example, two competing companies building the same product may need distinct methods because of differing values, budgets, product metrics, IT infrastructure, team size, skill levels, and allocation models.

Thus, a company or team handling projects with multiple variables should adopt a mix of methods, which requires deliberate planning; a great plan is one of the key ingredients for successful software development.

Recently I consulted a company developing a large blockchain product with three development teams—one in Asia, one in Europe, and one in the US—each with diverse backgrounds.

Each team also has different priorities: the first needs frequent releases, the second requires longer testing and validation, and the third focuses on research and development.

They tried to find a single process to support all three teams, only to realize that each team needs a workflow that maximizes its efficiency, even when using the same product, infrastructure, and project manager.

Framework/Method

We must recognize that framework solutions such as Scrum, XP, DevOps, etc., are not the ultimate answer.

In other words, we should examine each project's variables and then select an answer from a set of predefined framework options.

To obtain the best software development method, we need to assess the project's characteristics and design a personalized approach.

This does not mean ignoring existing models; on the contrary, we should learn as much as possible about current processes, frameworks, and practices.

Ideally, we should deeply understand the history and rules behind each method, focusing on principles rather than merely how they are practiced, especially when designing a brand‑new approach.

We can then use existing models as benchmarks, mix elements that make sense in reality, keep the useful ones, and discard the unnecessary.

Coordination and Continuous Improvement

Just as when designing a new product, do not waste excessive time perfecting the development method; keep it as simple as possible.

Then start using it to collect real feedback. Assign someone—whether called a project manager, process manager, or technical manager—to coordinate anything related to the new method.

This person must also focus on continuous improvement, which is the most critical factor for keeping the method healthy and valuable over the long term.

Company priorities, technologies, product scope, and other variables constantly change, so the method must evolve continuously to keep up.

Summary

There is no silver bullet. Each project has unique characteristics and therefore requires a custom‑tailored development method.

Framework‑type solutions are rarely the best fit; to find the optimal approach, you must design your own method based on your project's specific traits.

Designing your own method starts with deeply studying all existing methods, processes, frameworks, and practices.

Keep it simple, apply it quickly, and improve it based on actual feedback. Assign a dedicated planner to oversee the new development method, and continuous improvement is essential.
