Are you a fan of Moscow or MoSCoW?

Moscow, with its towering landmarks and rich history, is a city that’s always been on my bucket list. But today, we’re not packing our bags for Russia. Instead, we're about to embark on a different kind of journey—one where we learn to cook up a recipe that can save us from creating a software disaster. Welcome to the world of MoSCoW!

MoSCoW isn’t a city, but it might just be the secret sauce you need to turn your software development projects from chaotic to well-ordered.

Imagine you're preparing a grand feast with limited time and resources. How do you decide which dishes are essential, which are delightful add-ons, and which can be left on the table? This is the very challenge that agile software teams face when deciding which features to build next—and it's where the MoSCoW method comes into play.

The Birth of MoSCoW

In agile development, project teams often face an overwhelming number of potential features and improvements. With finite time and resources, it's crucial to distinguish between what's absolutely necessary and what's simply nice to have.

Software development expert Dai Clegg created the MoSCoW method while working at Oracle. He designed the framework to help his team prioritize tasks during development work on product releases.

It is a prioritization framework that segments features into four clear categories:

• M – Must have
• S – Should have
• Co – Could have
• W – Won't have (this time)

This method not only keeps teams focused on delivering a minimum viable product, but it also ensures that everyone—from developers to stakeholders—is on the same page about what truly matters.

Jorge’s Culinary Adventure

Meet Jorge, a passionate chef tasked with preparing a feast for a special event. Jorge’s challenge mirrors that of an agile team: delivering a successful outcome under constraints. Here's how Jorge uses a similar prioritization approach in his kitchen:

Must Have (M)

Jorge starts by listing the dishes that are absolutely essential. These are the non-negotiables—without them, the event would simply fall flat. In his feast, these might be:

• The main course, the centerpiece of the meal.
• A simple, yet satisfying appetizer.
• Basic beverages to ensure everyone stays refreshed.

For agile teams, "Must haves" are the core features without which the software cannot function. They represent the foundational elements of the product. For example, if you’re releasing a healthcare application, a must-have initiative may be security functionalities that help maintain compliance.

The “must-have” category requires the team to complete a mandatory task. If you’re unsure about whether something belongs in this category, ask yourself the following.

Should Have (S)

Next, Jorge identifies dishes that, while not critical, are highly important and enhance the overall experience—perhaps a special side dish that complements the main course. Similarly, agile teams designate features that improve usability and performance but are not strictly necessary for the product’s core functionality. For example, performance improvements, minor bug fixes, or new functionality may be “should-have” initiatives. Without them, the product still works.

Could Have (Co)

With some extra time and resources, Jorge considers adding garnishes or desserts. These are the “nice-to-haves”—if the schedule permits, they elevate the overall experience. In agile development, these features are desirable enhancements that can be included if the project timeline allows. For example, customizable themes, additional language options, or non-essential integrations with third-party tools may be “could-have” initiatives.

Won't Have (W)

Finally, Jorge acknowledges some extravagant dishes he once dreamed of including, but for this event, they are impractical. Placing initiatives in the “will-not-have” category is one way to help prevent scope creep. If initiatives are in this category, the team knows they are not a priority for this specific time frame.?

Some initiatives in the “will-not-have” group will be prioritized in the future, while others are not likely to happen. Some teams decide to differentiate between those by creating a subcategory within this group.

How MoSCoW Helps Manage Priorities

For Jorge, this method means clarity in the kitchen:

• Focus on Essentials: He ensures that the foundation of the feast is solid by prioritizing must-have dishes.
• Efficient Resource Use: With limited ingredients and time, Jorge allocates resources to what truly matters.
• Built-in Flexibility: If a dish can’t be prepared in time, the overall event still shines thanks to his prioritized plan.

Agile teams enjoy the same benefits. By categorizing features, they:

• Deliver Value Quickly: Focusing on "Must have" features means a viable product is always delivered on time.
• Promote Transparency: Clear priorities ensure that everyone understands the project’s roadmap.
• Adapt to Change: With a clear hierarchy of needs, teams can easily shift focus when unexpected challenges arise.

How Can Development Teams Use MoSCoW?

While Dai Clegg originally developed the MoSCoW method to help his team prioritize tasks under tight time constraints, it’s a versatile tool that can address various other limitations as well.

• Prioritizing Based on Budget What if the limitation is not time, but a tight budget? In this case, the team can use MoSCoW to identify the essential features (Must-Haves) and the important add-ons (Should-Haves). Then, by keeping the budget in mind, they can figure out what can realistically be accomplished within the financial constraints.
• Prioritizing Based on Team Skillsets Another limitation might be the skillsets of the team. If the product roadmap includes functionality the team isn't equipped to build, they can use MoSCoW to prioritize features that match their current capabilities while temporarily placing others on the back burner.
• Prioritizing Based on Competing Company Needs Lastly, a development team might find themselves juggling competing priorities from different departments. If the executive team imposes strict deadlines for multiple releases, MoSCoW can help the team focus on the Must-Have aspects of their desired release, while temporarily pushing everything else to the backlog.

Jorge’s culinary adventure isn’t just about a feast—it’s a masterclass in turning chaos into clarity. With MoSCoW, every dish (or feature) finds its perfect spot on the menu, setting the stage for success even under pressure. Ready to explore how this method can transform your project’s recipe?
