A scrum team typically consists of around seven people who work together in short, sustainable bursts of activity called sprints, with plenty of time for review and reflection built in. This implies that we need to break the big stories into smaller stories as they make their way up the list. Sprint Review This is the public end of the sprint; invite any and all stakeholders to this meeting.
Directo y al grano que es scrum, sus elementos como se usan y como se termina. Much of the original writing about scrum assumed a month-long sprint, and at the time that seemed breathtaakingly short indeed! If you have a two-week sprint, then this meeting might need one to two hours. We recommend one hour per week, every week, regardless of the length of your sprint. This is a decision for the business.
Sep 11, Ishan rated it breathtakungly was amazing. Jan 25, Ken Lenoir rated it it was amazing. Is there enough incremental value present to take the current product to market? The table below maps out the various meetings you would schedule during a one-week sprint. I liked how the author referred to customer needs as their stories and then each story involves multiple tasks instead of using boring project terminologies!

This meeting is not a decision-making meeting. The development team is highly collaborative and self-organizing.

Each of these users stories, when completed, will incrementally increase in the value of the product. For this reason, we often say that each time a user story is done we have a new product increment.
The scrum master acts as a coach, guiding the team to ever-higher levels of cohesiveness, self-organization, and performance. The scrum master helps the team learn and apply scrum and related agile practices to the team's best advantage. The scrum master is constantly available to the team to help them remove any impediments or road-blocks that are keeping them from doing their work. This is a peer position on the team, set apart by knowledge and responsibilities not rank.
High-performing scrum teams are highly collaborative; they are also self-organizing. The team members doing the work have total authority over how the work gets done.
The team alone decides which tools and techniques to use, and which team members will work on which tasks. The theory is that the people who do the work are the highest authorities on how best to do it. Similarly, if the business needs schedule estimates, it is the team members who should create these estimates. A scrum team should possess all of the skills required to create a potentially shippable product.
Most often, this means we will have a team of specialists, each with their own skills to contribute to the team's success. However, on a scrum team, each team member's role is not to simply contribute in their special area. The role of each and every team member is to help the team deliver potentially shippable product in each sprint.
Often, the best way for a team member to do this is by contributing work in their area of specialty. Other times, however, the team will need them to work outside their area of specialty in order to best move backlog items aka user stories from "in progress" to "done. So, how many team members should a scrum team have? The common rule of thumb is seven, plus or minus two.
That is, from five to nine. Fewer team members and the team may not have enough variety of skills to do all of the work needed to complete user stories.
More team members and the communication overhead starts to get excessive. The product backlog is the cumulative list of desired deliverables for the product. This includes features, bug fixes, documentation changes, and anything else that might be meaningful and valuable to produce. The list of user stories is ordered such that the most important story, the one that the team should do next, is at the top of the list.
Right below it is the story that the team should do second, and so on. Since stories near the top of the product backlog will be worked on soon, they should be small and well understood by the whole team. Stories further down in the list can be larger and less well understood, as it will be some time before the team works on them. Unlike the product backlog, it has a finite life-span: the length of the current sprint. It includes: all the stories that the team has committed to delivering this sprint and their associated tasks.
Stories are deliverables, and can be thought of as units of value. Tasks are things that must be done, in order to deliver the stories, and so tasks can be thought of as units of work.
A story is something a team delivers; a task is a bit of work that a person does. Each story will normally require many tasks. A burn chart shows us the relationship between time and scope. Time is on the horizontal X-axis and scope is on the vertical Y-axis.
A burn up chart shows us how much scope the team has got done over a period of time. Each time something new is completed the line on the chart moves up. A burn down chart shows us what is left to do. In general, we expect the work remaining to go down over time as the team gets things done.
Sometimes the work remaining changes suddenly, when scope is added or removed. These events appear as vertical lines on the burn down chart: a vertical line up when we add new work, or down when we remove some work from the plan. When the team's tasks are visible to everyone from across the room, you never have to worry that some important piece of work will be forgotten. The simplest task board consists of three columns: to do, doing and done.
Tasks move across the board, providing visibility regarding which tasks are done, which are in progress, and which are yet to be started. This visibility helps the team inspect their current situation and adapt as needed.
The board also helps stakeholders see the progress that the team is making. Done is a wonderful word; when the team gets a user story done it's time to celebrate! But sometimes there is confusion about exactly what that word "done" means.
A programmer might call something done when the code has been written. The tester might think that done means that all of the tests have passed. The operations person might think that done means it's been loaded onto the production servers. A business person may think that done means we can now sell it to customers, and it's ready for them to use.
This confusion about what "done" means can cause plenty of confusion and trouble, when the salesperson asks why the team is still working on the same story that the programmer said was done two weeks ago! In order to avoid confusion, good scrum teams create their own definition of the word "done" when it is applied to a user story. They decide together what things will be complete before the team declares a story to be done.
The team's definition may include things like: code written, code reviewed, unit tests passing, regression tests passing, documentation written, product owner sign-off, and so on. This list of things that the team agrees to always do before declaring a story done becomes the teams "definition of done.
When the team thinks a story is done, they all gather around and review each item, to confirm that it has been completed. Only then will the team declare the story as done. The sprint is the foundational rhythm of the scrum process. Whether you call your development period a sprint, a cycle, or an iteration, you are talking about exactly the same thing: a fixed period of time within which you bite off small bits of your project and finish them before returning to bite off a few more.
At the end of your sprint, you will be demonstrating working software or thy name is Mud. A breif intro to scrum Not a detailed description of things but to get going this is enough.
Product Owner A development team represents a significant investment on the introduciton of the business. The retrospective, held at the very end of each and every sprint, is dedicated time for the team to focus on what was learned during the sprint, and how that learning can be applied to make some improvement. The theory is that the people who do the work are the most inrtoduction in how best to do it. It is all about constant feedback from concerned stockholders and teamwork and being transparent about the obstacles and issues during the project life cycle.
Fewer team members and the team may not have enough variety of skills to do all of the work needed to complete user stories. There are salaries to pay, offices to rent, computers and software to buy and maintain and on and on. Remember that stories are deliverables: For this reason, we often say that each time a user story is done we have a new product increment. But it really does pertain pretty specfically to iterative software design and testing work. The Sprint Cycle The sprint cycle is the foundational rhythm of the scrum process.
This implies that we need to break the big stories into smaller stories as they make their way up the list. Want to Read saving…. This is a peer position on the team, set apart by knowledge and responsibilities not rank. A scrum team should possess all of the skills required to create a potentially shippable product. So, why do we do development work in these short cycles?

In order to deliver a story, team members will have to complete tasks.
