What is Spike in Scrum? A Comprehensive Exploration

Are you a Scrum team member aiming to optimise your project’s workflow and seeking the ideal approach to tackle complex tasks? If you’re new to Agile methodologies or looking to enhance your Scrum practices, understanding What is Spike in Scrum can significantly help with this. With the variety of Scrum Artifacts and events, the challenge lies in effectively integrating Spikes into your sprints. 

A Spike is a backlog item distinctive to Scrum, aimed at solving a highly difficult to estimate problem or one that is quite unknown. In this blog, we will discuss What is Spike in Scrum and understand technical challenges, design issues, or feasibility questions related to it. This will greatly assist in accurate planning and execution of future work.

What is Spike in Scrum? 

A Scrum Investigation, also called Spike, aims to clarify the team’s doubts or incorrect estimate of a task. Normally time-limited, Spikes' purpose is to research new technologies, explore possible solutions, or better understand an involved problem. 

The intention is to minimise risk and use precise planning to make informed decisions and provide the required information. Spikes are good to go in Agile environments where the team brings flexibility and adaptability, helping to navigate the path of unknowns well for subsequent development works.
 

When can you use Spike? 

A Spike, for instance, can be a necessary tool for uncovering unknowns or solving a complex issue hindering a team's speed in the Agile development process. In the case of a technical challenge with many ways out, a spike can easily go through them to choose the right solutions. 

Additionally, when a new technology or tool is being planned for incorporation into a project, Spike will give a concentrated period for researching and experimenting to determine feasibility and possible impact. It's also helpful for providing evidence for decision-making, collecting information, and refining user stories to obtain correct preparation and estimation. 

Different types of Spikes in Scrum 

In Scrum, Spikes are mainly of two types, and each has a different goal for removing the uncertainties of a project. Let's discuss these types:
 

1) Functional Spike 

A Functional Spike examines issues related to the application's functions to better understand the user's requirements and needs. Such a Spike is suitable when there is ambiguity regarding how a feature should work from the user's standpoint or when the team may need to verify the assumptions regarding user interactions. 

The ultimate target is to investigate viable options, make informed decisions to improve the User Experience, and ensure that the development corresponds to user expectations and requirements. 

2) Technical Spike 

Technical Spikes are concentrated on intellectual confusion arising from a project's technical aspects. This could be done by studying new technologies, tools, or frameworks to learn whether they are consistent with the project's purpose, resolving complicated technical problems, or choosing a particular technical method to implement a feature. 

They help the team manage the risks associated with technical issues, ensuring that architecture and tech stacks meet the project's long-term goals and objectives.

Key considerations regarding Spikes

Here are some key considerations that you need to consider regarding Spikes:

1) Clearly define spike goals 

The success of Spike begins with a clear grasp of what it stands for. Before launching it, it is imperative to define Spike's primary questions or ambiguities, which it purposes to solve or answer.  

The team goal has to be unambiguous so that it is not off the mark and team effort is channeled toward progress of the project and the outcomes of the spike can be eliminated to actionable and meaningful contributions. This clarity assists by pinning down the target in the direction of the whole goal. 

2) Identify Spikes in backlog refinement meetings 

Spikes are identified during backlog refinement meetings, where the team reviews and prioritises backlog items. Identifying Spikes at this stage allows for strategic planning. It ensures that they are integrated into the sprint with a clear understanding of their impact on the team's capacity and the sprint's goals. It also lets the whole team contribute to the definition and scoping of the Spike. 

3) Estimate spike efforts like user stories 

However, when it comes to development, Spikes differ from user stories, which require an estimate of the effort for sprint planning. Viewing Spikes as user stories about pointing allows for managing team capacity and ensuring that the time spent on Spikes does not detract from completing the rest of the sprints. 

4) Tackle Spikes in cross-functional teams 

Many times, Spikes cover fields in which individuals' differing perspectives and talents are all needed. Include staff members from different departments or functions to ensure a thorough investigation of the challenges. Interaction inspires people to exchange information and concepts, culminating in comprehensive research and unique approaches. Furthermore, it creates belongingness that transmits to the whole team. 

5) Define acceptance criteria for clear outcomes 

Along with user stories, Spikes have clear acceptance criteria to make the success clear. These criteria offer a good basis for evaluating Spike's outcomes and provide meaningful information that can be applied to the project and produce results. Acknowledging the precise acceptance criteria allows the team to get the things done and check if the Spike fully aligns with its purpose. 

6) Timebox Spikes for focused work 

Scrum Timebox is fundamental for the project completion on time and effectively utilising Spike meetings. Through Spikes's duration restriction, i.e., a solitary sprint, time-boundedness becomes the prime factor persuading teams to work with focus and speed. Timeboxing eliminates the possibility of Spikes stretching on and on until they lose their reason to exist and become a stumbling block instead.

Advantages of using Spikes in Scrum 

Incorporating Spikes into Scrum processes brings numerous benefits that streamline and enhance project outcomes: 

a) Clarifies complex issues: Spikes go deep to the areas of complexity or ambiguity, providing clarity and eliminating points of dispute, smoothing out the development process. 

b) Supports accurate estimations: They help resolve uncertainties, thus making task time and resource estimations more accurate and improving the accuracy of Sprint Planning. 

c) Promotes technical exploration: They provide a secure background for technical research and discovery of new technologies or approaches, which leads to creativity and efficient solutions. 

d) Enhances team collaboration: Spikes imply collaboration among team members, where different skills and visions are used to solve problems, leading to team cohesion and effectiveness. 

e) Facilitates knowledge acquisition: Spikes allow users to acquire new skills and knowledge, fueling personal and team growth. 

f) Increases product quality: They enable in-depth research and problem solving, which leads the company to produce high-quality features and products. 

g) Enables risk mitigation: Spikes helps mitigate risks at the time of the project initiation, thus preventing them from becoming a substantial problem later on. 

h) Optimises resource allocation: Time invested in Spikes allows for application of resources to where they matter the most, thus avoiding unnecessary allocation of resources to tasks that do not require much effort.
