So, on software teams, Single Item Flow has usually been taken to mean that the whole Team has all the skills it needs (no need for SMEs), and works on a Story until it’s Done, and then the Team moves on to another Story. Please try again later. That is, when a Story is Done and the Team is deciding what to do next, the Stories that are eligible to Swarm on next can come from anywhere in the Backlog, not just from the Sprint Backlog. On average, it takes 15 minutes to get your brain back to the level it was at before you answered that phone call or email. Single Item Flow (also called ‘single piece flow’ or ‘one piece flow’) is a lean manufacturing concept that says each individual Item will move through the manufacturing process all at once with no waiting between steps.

But that’s ok, since Single Item Flow doesn’t necessarily require the whole Team.

From an average of about an hour to half an hour, sometimes less. And not just for the reason we’ve outlined above. However, this tendency can get out of hand to the point where teams find themselves with multiple requirements started, but none of them finished. Then that process efficiency is driven to over 100% and that automatically drives an increase in velocity.”.


Here’s how Jeff explains it. They all need to be completed before the end of the Sprint, but only one of these items can be the team’s top priority. Scrum teams should always be pushing themselves. Copyright 2019 © Scrum Inc. All rights reserved. Swarming also boosts the productivity of Scrum Teams by improving the important metric known as process efficiency, defined as the amount of actual work time needed  to finish an item on the backlog divided by the calendar time it takes to get it to done. The product owner decides the priority when faced with this decision. An Example of Agile Swarming Patterns: In the Hospital. As Dr. Jeff Sutherland, co-creator of Scrum and founder of Scrum Inc. points out, “Many organizations today have individuals, teams, and even the organization itself working on many projects that are all top priority.”, This, he adds, creates massive dysfunction and slows down the teams and organization. This seems wasteful to most people, so most Teams don’t want to do it.

The average process efficiency of a typical scrum team is five or 10%. And one the cleaning crew came to on their own. Everything is open and nothing is done.”, This, explains Jeff, decreases the velocity of a team by creating a bottleneck at the end of the Sprint “where everything has to be tested at once, but there's not enough time to do that and the sprint fails.”. In fact, he probably helps write the online documentation for each Story and also gathers whatever else he needs for the other documentation he is responsible for (User Manuals, Marketing Materials and so on). Swarming is a technique that helps agile teams to do this.

A high percentage of sprint backlog completion should be the goal, but it should not be expected that scrum teams will hit 100 percent every time. Since this coder should not be Coordinating a coding Story at the same time, we say that the Team has kept one coder in reserve to act purely as a Swarmer. Swarming occurs when as many team members as possible work simultaneously on the same priority item. Additional Benefit of Agile Team Swarming. The most important requirements get done, done completely, and get done first. The results were that multitasking just doesn’t work. Click here to watch on YouTube! Stop starting and start finishing. As development teams push themselves, scrum masters, like aeronautical engineers, help the scrum team find ways to reduce drag to become more effective and accomplish more in each sprint.

Having multiple TeamLets each doing Single Item Flow is a fine idea and is basically what the Team Swarm concept is trying to achieve. The book is 528 pages long and contains 94 Scrum patterns. For that we turn to a section of The Scrum Fieldbook by Scrum Inc CEO JJ Sutherland. In this pattern, each coding Story gets a coder as its Coordinator (remember that not all Stories are coding Stories). This might be the best option if plenty of time is left in the sprint to complete the current tasks and the rejected requirement. Those distractions come at a cost. Many Scrum Teams try to divide and conquer their backlogs by having individual members work on different items at the same time. The thinking is this will lead to more being done since the work is happening at the same time. Swarming occurs when as many team members as possible work simultaneously on the same priority item. In other words, there can be no Swarmers that have skills which are required by more than one TeamLet at a time.

And they work on just that one item until it is done. It took about an hour for the cleaning crew to do the job. Swarming is a simple but often overlooked way to immediately boost the velocity of any Scrum Team. Swarming also boosts the productivity of Scrum Teams by improving the important metric known as. It is a pattern consistently used by hyper-productive teams in any industry. Still, swarming may sound counterintuitive. Swarming is the act of all development team members working on only one requirement at a time during the sprint. Every time you switch focus from one thing to the next, you lose a sizable percentage of your productivity. The Team Swarm is a pattern that well-formed Teams use, as it focuses on the needs of the Stories, adapting the Team’s organization and behavior based on those needs. All without sacrificing quality.”.
This takes some careful coordination between the TeamLets in order to use these specialists without interrupting the flow of any of them, but this is why the Team self-organizes all the time, isn’t it? Known as the “wheels out” to “wheels in”  time in reference to the gurneys that carry the patients. “What if you put three people on that story,” asks Jeff, “and they all worked on it together and they got it done in one day? And they work on just that one item until it is done. Swarming is a simple but often overlooked way to immediately boost the. Swarming enables teams to enjoy the following benefits: Maximized chances for success with the skills and abilities of the entire team focused on a single requirement. Every sprint will produce “shippable” results. We refer to these people as Professional Swarmers and their primary production responsibility is to augment, support and provide expertise, brainpower and additional muscle to existing TeamLets. This is because their primary responsibility is to Swarm, and their own Stories are of secondary concern in most Sprints. Swarming was a key process improvement. It’s not just sterilizing the room.

Stay-at-Home Coder. Both Pairing and Polygamous Pairing are stylized forms of Swarming; however, only in the Polygamous case are there actual Swarmers. The only significant difference is that the Stories that are eligible to be Swarmed on next are not already agreed to. It is generally accepted that coders have a tough time context switching; that is, when they are buried deep in a piece of code and they have to come out to do something else, it then takes them awhile to get back ‘into the code.’ Therefore, one of the patterns of Swarming is the Stay-at-Home Coder pattern. Thus allowing individuals to learn or improve skill sets. Individual efficiency does not optimize production while … We’ve even seen jumps as high as 200%. When looked at this way, strict Pairing of Developers is a form of Single Item Flow, since nobody but the Pair works on the Story, and that’s all the Pair works on until it is Done; there are no required Swarmers. adroll_version = "2.0"; “This is no easy task,” writes JJ, “, Think about it. Efficiency is 10%.”, Here’s where swarming changes the game. adroll_pix_id = "VMULUAIUQZBZNBGN2T74KD";

If you don’t have enough people to take on the workload as dedicated, swarming developers, you definitely don’t have time to thrash them. This concept, called “Context Switching” was first laid out by author Gerald Weinberg in his seminal book Quality Software Management. In other words, these non-coders will be Coordinators for non-coding Stories and Swarm on the coding Stories, while the coders will ‘stay-at-home’ with their individual coding Story – they will only Swarm after their story is Done. The non-coders on the Team (analysts, testers and so on) then become Swarmers who share their expertise across all the coding Stories as well as work on the non-coding Stories. For that we turn to a section of, Known as the “wheels out” to “wheels in”  time in reference to the gurneys that carry the patients.
