Client-side JavaScript runs in the user’s browser, which makes it inherently unreliable for enforcing critical functionality. Network issues, browser quirks, or code errors can prevent scripts from executing correctly, leading to unexpected or inconsistent behavior. Additionally, client-side code is fully exposed to users, which creates potential security risks.

I’m often reminded that even experienced executives, salespeople, project managers, and business analysts have different processes and ways of working. Not everyone has had the same opportunities or experiences when it comes to executing software projects. We all come from different backgrounds, and not everyone has had the benefit of hands-on experience across the full project lifecycle. Over time, some may become removed from day-to-day operations and lose sight of the detailed steps required to implement a project successfully.

The process I describe here is one I’ve developed in collaboration with various teams, across multiple agencies, and on dozens of projects—while working in roles spanning development, project management, sales, and strategy. It has evolved through trial and error and been refined through real-world application. While it’s framed around frontend user interfaces (or “theme” implementation) for ecommerce websites, I’ve found it flexible enough to apply to almost any software project—including fully custom implementations.

Following this structured feature implementation process allows projects to run more smoothly, improves estimate accuracy, sets clearer client expectations, and ultimately leads to higher-quality outcomes—efficiently and effectively.

Every successful replatform begins with a fundamental question: “What’s holding us back?”

This question delineates the difference between a tactical feature update and a strategic platform investment. The decision to replatform is never arbitrary—it stems from recognizing that existing infrastructure limits growth, agility, or innovation. Teams must hold this front and center throughout the project to avoid costly distractions that dilute focus.

Every purchase is a decision. Consciously or not, customers are asking themselves: Why should I buy from you instead of someone else?

It’s tempting to think the answer is obvious—maybe your website looks better, your products are cheaper, or your shipping is faster. But in reality, the reasons are more complicated. Customers weigh a mix of factors, and the “most important” one often shifts depending on the situation.

Discover what really drives customers to choose you over competitors—from selection and price to trust and assurance.

Launching a new website or feature always brings the same question: when is it ready?

Is something truly “done” when it still contains bugs? Can a deliverable be considered complete if it only meets part of the requirements? And, perhaps more importantly, when is it better to ship what you have rather than wait for something more polished?

Find a balance between speed and quality that makes sense for your business.
