What is Vertical Slicing and How it’s Used in Project Management (2023 Updated)

Does managing a project feeling like trying to eat an elephant whole? Here’s something you might not know: breaking your work down into smaller, more manageable tasks using vertical slicing can make it easier than ever.

This blog post is designed to shine a light on what vertical slicing is and how it’s used in project management, ultimately helping you navigate through projects with less stress and more efficiency.

Key Takeaways

• Vertical slicing is a project management approach that involves breaking down a feature into smaller, functional pieces to be developed and delivered incrementally.
• It differs from horizontal slicing, which focuses on completing tasks or parts of a job rather than delivering a full feature.
• Vertical slicing is important in project management because it allows teams to show steady progress, deliver value early and frequently, and gather feedback to make necessary adjustments.

Understanding Vertical Slicing

Vertical slicing is a project management approach that involves breaking down a feature into smaller, functional pieces to be developed and delivered incrementally.

Definition and purpose

Vertical slicing is a key part of project work. It’s like cutting a cake into thin, tall pieces. Each piece has all the layers of the full cake, just like how each slice of a project has every part of that job in it.

A team will take one slice and finish it end-to-end in one go-round or cycle. The big aim is to give something working and useful at the end of each cycle. This way they show steady work done and can get quick feedback from people who want to use what they make.

It’s used often when teams follow agile ways to manage their work as it’s good for speeding up getting things done and showing value fast.

How it differs from other approaches (horizontal slicing)

Vertical slicing is not the same as horizontal slicing. They are two different ways to break down work in a project. In vertical slicing, we deliver a full feature from top to bottom in one go.

The whole team works on it, so there’s crossfunctional work involved. It can be like making a thin slice all through a cake.

Horizontal slicing is more about tasks or parts of a job. Each layer gets done bit by bit, and it’s usually tech focused. It would be like taking off just the icing or just the middle layer of that same cake.

So you see, each type has its own purpose and use! Vertical slicing gives us an end-to-end feature faster and makes progress clear for everyone: the team and outside folks too! But it may need more planning up front to do right.

Importance in project management

Vertical slicing plays a big role in project management. It breaks down work into small, focused parts. Each slice gives a full view of the project from start to end. This helps teams show steady progress.

Early and often, it delivers value, which is good for everyone involved in the project. Rapid feedback and change can happen because of this method. The idea gets proven sooner with vertical slicing because you are pushing out working products every step of the way.

The Vertical Slice in Action

To implement vertical slicing, a feature is broken down into smaller, functional slices that can be independently developed and delivered. This approach allows for quicker feedback from stakeholders and ensures value delivery at each iteration.

Breaking down a feature for vertical slicing

To implement vertical slicing in project management, breaking down a feature into smaller, manageable pieces is crucial. Here’s how it can be done:

• Identify the feature to be sliced.
• Determine the functionality or user value of the feature.
• Split the feature into smaller user stories or tasks.
• Consider dependencies and prioritize the order of implementation.
• Define clear acceptance criteria for each slice.
• Assign each slice to a team member for development and testing.
• Deliver each slice incrementally, ensuring end-to-end functionality.
• Gather feedback from stakeholders and make necessary adjustments.

Benefits of using this approach

Vertical slicing offers several benefits when it comes to project management. One key advantage is that it allows for faster value delivery. By breaking down work into small, narrow-focused pieces, teams can deliver features or functionality end-to-end in a single iteration.

This means that stakeholders and users can start benefiting from the project sooner, as they don’t have to wait for the entire system or product to be developed before seeing results.

Another benefit of vertical slicing is increased transparency and feedback. With each iterative release, teams can demonstrate incremental progress and gather valuable feedback from stakeholders and users.

This helps identify any issues or changes needed early on, allowing for quicker adjustments and improvements.

Furthermore, vertical slicing provides a holistic view of the project’s development. Each slice includes a bit of every layer or component involved, offering a comprehensive understanding of how everything fits together.

This makes it easier to showcase the value and potential of the project to stakeholders.

Real-life examples of vertical slicing in software development

In software development, vertical slicing is commonly used to deliver features or functionality in small, focused increments. For example, let’s say a team is working on creating an online shopping website.

Instead of building the entire website at once, they can use vertical slicing to focus on specific parts first. They might start by developing a feature that allows users to browse products and add them to their cart.

This would involve working on the front-end design, back-end functionality, and database integration all together in one iteration. Once this slice is complete, it can be tested and released as a standalone function before moving on to other features.

This approach allows for quicker feedback from stakeholders and makes it easier to make changes based on user needs or market demands.

Another real-life example of vertical slicing can be seen in video game development. Game developers often create small sections or levels of a game called “vertical slices” that demonstrate key gameplay mechanics, graphics, sound effects, and overall feel of the game.

Implementing Vertical Slicing in Project Management

To implement vertical slicing in project management, prioritize user stories and ensure the INVEST principles are met for efficient iterative development and delivery. Explore tools that can optimize the vertical slicing process.

Prioritizing user stories

Prioritizing user stories is an important aspect of implementing vertical slicing in project management. Here are some key points to consider:

• User stories should be prioritized based on their value to the end – users or stakeholders. This ensures that the most important features or functionalities are delivered first.
• Prioritization can be done by considering factors such as business impact, customer feedback, market trends, and project goals.
• The team should collaborate with stakeholders to gather their input and align on the priorities.
• A backlog of user stories can be created, with each story assigned a priority level.
• Regular reviews and refinements of the backlog should be conducted to ensure that it stays up-to-date and reflects any changes in priorities or requirements.

Ensuring INVEST principles are met

The INVEST principles must be met to ensure successful vertical slicing in project management. These principles help guide the process and ensure that the sliced features or functionality are valuable and deliverable. Here are the key aspects to consider when implementing INVEST:

Iterative development and delivery

Iterative development and delivery is a key aspect of vertical slicing in project management. It involves continuously building, testing, and refining features or functionality throughout the project timeline.

With this approach, teams can deliver value incrementally in each iteration rather than waiting until the end to showcase progress. This helps to increase transparency and gather feedback early on, allowing for faster iteration and improvement.

By delivering small portions of work at a time, stakeholders can see tangible results and provide input for further development. It also ensures that any changes or modifications can be implemented quickly, leading to more efficient project execution.

Using tools for efficient vertical slicing

To efficiently perform vertical slicing in project management, teams can utilize various tools. One helpful tool is user story splitting, which allows breaking down features into smaller, manageable tasks.

Another useful tool is the INVEST principle, which helps prioritize user stories based on their value and feasibility. Additionally, iterative development and delivery enable frequent feedback and course correction.

By leveraging these tools, teams can streamline their work processes and ensure efficient vertical slicing for faster value delivery.

Comparing Vertical and Horizontal Slicing

Vertical and horizontal slicing are two approaches used in project management, each with its own set of pros and cons.

Pros and cons of each approach

There are advantages and disadvantages associated with both vertical and horizontal slicing. Let’s examine them in more detail in the following table:

Choosing the right approach depends on the project’s complexities, team structure, and objectives.

Choosing the right approach for your team

When deciding between vertical slicing and horizontal slicing, it’s important to consider your team’s specific needs and goals. Vertical slicing is ideal if you want to prioritize delivering value early and frequently, as it allows for faster feedback and iteration.

It also enables you to showcase the potential of your project to stakeholders by demonstrating incremental progress across all layers of development. On the other hand, horizontal slicing may be more suitable if you need to focus on technical components and tasks within each layer.

Ultimately, choosing the right approach depends on what will work best for your team in terms of efficiency, transparency, and value delivery.
