Some features and user stories may require both types of spikes. Develop confidence about the desired solution path.Evaluate specific technical implementation approaches.Evaluate the potential performance or load impact of a new user story.Technical spikes – They are used to research various approaches in the solution domain. How to use insights to influence implementation decisions.Spikes primarily come in two forms: technical and functional.įunctional spikes – They are used to analyze overall solution behavior and determine the following: Spikes may involve creating a small program, research activity, or test demonstrating new functionality. ![]() Gain confidence in a technical or functional approach, reducing risk and uncertainty.Conduct primary research to familiarize them with a new technology or domain.Perform feasibility analysis and other activities that help determine the viability of Epics.Estimate new Features and Capabilities to analyze the implied behavior, providing insight into the approach for splitting them into smaller, quantifiable pieces.Teams may use spikes in a variety of situations: When faced with a question, risk, or uncertainty, Agile Teams conduct small experiments before moving to implementation rather than speculate about the outcome or jump to a Solution. DetailsĪgile and Lean value facts over speculation. They also provide a mechanism and workflow that Agile Release Trains (ARTs) use to help determine the viability of Epics. Like other stories, spikes are estimated, implemented and demonstrated. Their purpose is to gain the knowledge necessary to reduce the risk of a technical approach, better understand a requirement, or increase the reliability of a story estimate. Defined initially in Extreme Programming (XP), spikes represent activities such as exploration, architecture, infrastructure, research, design, and prototyping.

That is the where agile excels and allows you deliver incrementally. Much of the agile varieties actually encourage you do things without knowing everything. My experience has been that teams tend to use Spikes as a way to thoroughly create specifications (old way). If so, conversations occur with PO to rethink. If the sprint backlog needs to be changed, you determine if that change endangers the sprint goal. Remember, the Dev Team forecasts a sprint backlog based on what they know at the time of planning. If they uncover something during the sprint, they inspect and adapt. By doing this I have found that they want far less Spikes and will instead lean on making stories more focused (or smaller if you prefer) so that any unknowns that are encountered can be dealt with as the information is found. And that only happens if there is something that is blocking the team from being able to understand something in the Product Backlog. Instead, I encourage them to put Spikes directly into the Sprint Backlog. I encourage my teams to not put Spikes in the Product Backlog.
