Collaborative Estimation Technique: Challenge, Estimate or Override (CEO)

Learn more about transforming people, process and culture with the Real Agility Program

Great technique described by Shahin Sheidaei on his blog: Challenge, Estimate or Override (CEO) Game for Effective Estimations.  It is much quicker than the Planning Game, and probably a bit slower than the Bucket System.

Pitfall of Scrum: Assigning Tasks

Learn more about transforming people, process and culture with the Real Agility Program

Even though the concept of self-organizing teams has been around for a long time, still some people think that a project manager or team lead should be assigning tasks to team members. Don’t do this!!!  It is better to wait for someone to step up than to “take over” and start assigning tasks.

Assigning tasks can be overt or subtle.  Therefore, avoid even suggestions that could be taken as assigning tasks. For example, no one should ever tell a Scrum Team member “hey! You’re not doing any work – go take a task!” (overt) or “This task really needs to get done – why don’t you do it?” (semi-overt) or “Would you consider working on this with me?” (subtle). Instead, any reference to tasks should be to the team at large. For example it would be okay for a team member to say “I’m working on this and I would like some help – would anyone help me?”

In the Scrum Guide, a partial definition of self-organizing is given:

Scrum Teams are self-organizing….. Self-organizing teams choose how best to accomplish their work, rather than being directed by others outside the team.

A more formal definition of the concept of “self-organizing” can be found here:

Self-organisation is a process where some form of global order or coordination arises out of the local interactions between the components of an initially disordered system. This process is spontaneous: it is not directed or controlled by any agent or subsystem inside or outside of the system; however, the laws followed by the process and its initial conditions may have been chosen or caused by an agent.

The key here is that there is no single point of authority, even temporarily, in a self-organizing team. Every individual member of the team volunteers for tasks within the framework of “the laws followed by the process” – namely Scrum. Scrum does define some constraints on individual behaviour, particularly for the Product Owner and the ScrumMaster. People in those two roles have specific duties which usually prevent them from being able to volunteer for any task. But all the other team members (the Development Team) have complete freedom to individually and collectively figure out how they will do the work at hand.

What If One Person Isn’t Working?

People who are managers are often worried about this.  What if there is one person on the team who just doesn’t seem to be doing any work? Isn’t assigning tasks to this person a good thing?  Scrum will usually make this bad behaviour really obvious. Let’s say that Alice hasn’t completed any tasks in the last four days (but she does have a task that she volunteered for at the start of the Sprint). Raj notices that Alice hasn’t finished that initial task. An acceptable solution to this problem is for Raj to volunteer to help Alice. Alice can’t refuse the help since Raj is self-organizing too. They might sit together to work on it.

Of course, that might not solve the problem. So another technique to use that respects self-organization is to bring it up in the Sprint Retrospective. The ScrumMaster of the team, Sylvie, chooses a retrospective technique that is designed to help the team address the problem. In a retrospective, it is perfectly acceptable for people on the team to be direct with each other. Retrospectives need to be safe so that this kind of discussion doesn’t lead to animosity between team members.

Remember: everyone goes through ups and downs in productivity. Sometimes a person is overwhelmed by other aspects of life. Sometimes a person is de-motivated temporarily. On the other hand, sometimes people become extremely engaged and deliver exceptional results. Make sure that in your team, you give people a little bit of space for these ups and downs.  Assigning tasks doesn’t make a person more productive.

What If There is One Task No One Wants to Do?

Dig deep and find out why no one wants to do it. This problem is usually because the task itself is worthless, frustrating, repetitive, or imposed from outside without a clear reason. If no one wants to do a task, the first question should always be: what happens if it doesn’t get done? And if the answer is “nothing bad”… then don’t do it!!!

There are, unfortunately, tasks that are important that still are not exciting or pleasant to do. In this situation, it is perfectly acceptable to ask the team “how can we solve this problem creatively?” Often these kinds of tasks can be addressed in new ways that make them more interesting. Maybe your team can automate something. Maybe a team member can learn new skills to address the task. Maybe there is a way to do the task so it never has to be done again. A self-organizing Scrum Team can use innovation, problem-solving and creativity skills to try to over come this type of problem.

And, of course, there’s always the Sprint Retrospective!

Why Self-Organize – Why Is Assigning Tasks Bad?

Autonomy is one of the greatest motivators there is for people doing creative and problem-solving types of work. The ability to choose your own direction instead of being treated like a mushy, weak, unreliable robot. Motivation, in turn, is one of the keys to creating a high-performance state in individuals and teams. The greatest outcome of good self-organization is a high-performance team that delivers great work results and where everyone loves the work environment.

Assigning tasks to people is an implicit claim that you (the assigner) know better than them (the assignees).  Even if this is true, it is still easy for a person to take offence.  However, most of the time it is not true.  People know themselves best.  People are best at assigning tasks to themselves.  And therefore, having one person assigning tasks to other people almost always leads to sub-optimal work distribution among the members of a team.

The ScrumMaster and Assigning Tasks

The ScrumMaster plays an important role in Scrum.  Part of this role is to encourage self-organization on a team.  The ScrumMaster should never be assigning tasks to team members under any circumstances.  And, the ScrumMaster should be protecting the team from anyone else who is assigning tasks.  If someone within the team is assigning tasks to another team member, the ScrumMaster should be intervening.  The ScrumMaster needs to be constantly aware of the activity on his or her team.

Pitfall of Scrum: Problem-Solving in the Daily Scrum

Learn more about transforming people, process and culture with the Real Agility Program

The Daily Scrum should not be used to find solutions to problems (obstacles, impediments) raised. Instead, keep the meeting very short and have those problem-solving conversations afterwards with only those who are interested. The ScrumMaster facilitates this meeting to keep it on track. The Daily Scrum is timeboxed to a maximum of 15 minutes, but often should be even less. With a good physical task board, a Daily Scrum can often be done in less than a minute simply by each team member pointing at the pieces of work they are working on.

From the Scrum Guide:

The Development Team or team members often meet immediately after the Daily Scrum for detailed discussions, or to adapt, or replan, the rest of the Sprint’s work.

In other words, don’t have those discussions during the Daily Scrum! The Daily Scrum is essential to creating transparency and implementing the Scrum value of Openness. The three questions of the Daily Scrum are effectively:

  1. What did I do since the last time we checked in as a team?
  2. What am I planning to do before the next check in time?
  3. What impediments, if any, are preventing us from getting our work done?

Each member of the team takes a turn and answers those three questions. This doesn’t have to be completely stilted, but it should be Focused (another value of Scrum) and efficient so that the need for other meetings is minimized. Accomplishing this takes some practice. The ScrumMaster helps the team to keep the timebox, but at first, a team might have challenges with this.

Struggling with the Daily Scrum

There are a some common reasons that a team might struggle with wanting to problem solve in the Daily Scrum:

  • One team member doesn’t know what to do next and it devolves into re-planning right there and then. A quick suggestion or two is probably fine, but it is a very steep slippery slope. A team can easily get into the habit of always doing this! The ScrumMaster needs to be vigilant about recommending that the discussion be taken up after the Daily Scrum is concluded in order to avoid this pitfall. This suggestion will be common when a team is first starting out.
  • One person mentions an impediment that someone else knows how to solve… and a third person has a different idea of solving it. In this situation it is much better for interested team members to just simply indicate “I have an idea for that,” and let the Daily Scrum continue. Then after the Daily Scrum those people have a quick discussion. This avoids wasting the time of everyone on the team with something that is only interesting to a few.
  • An individual doesn’t seem to have anything to report and other team members try to elicit more information. This should really be something that the ScrumMaster or the team’s coach should take up with the individual. It may be that there is an impediment that the person is uncomfortable sharing openly with the whole team. There is a subtle pitfall that may be revealed here: that the team does not have the safety to self-organize.
  • Disagreement about what to do next. This type of problem is the hardest to deal with because many people will feel that disagreements need to be resolved before any action can be taken. A good ScrumMaster will actually encourage competing ideas to be attempted. Learn by doing instead of by argument and analysis. This is the fundamental shift in culture that Scrum is attempting to put in place: an empirical approach to work rather than a defined approach.

Just beware: yet another pitfall (although not common) is to decide that the Daily Scrum shouldn’t be daily because it is taking so long. Unfortunately, making this change will often just make the meetings even longer until they devolve back into weekly status meetings reporting to the team lead!!! Remember that it’s not Scrum anymore if your team doesn’t meet together daily.

Ultimately, if a team is struggling with the Daily Scrum in any way, this is a valid topic for discussion in the Sprint Retrospective.

Link: Meeting Check-Ins

Learn more about transforming people, process and culture with the Real Agility Program

Very nice article called Why I Always Start a Meeting with a Check-In.  From the article by Ted Lord, senior partner, The Giving Practice:

The greatest benefit of working in a group is our diversity of viewpoints and approaches; groups hobble themselves when they don’t continually give attention to creating a container of trust and shared identity that invites truth-telling, hard questions, and the outlier ideas that can lead to innovation

One antidote to over-designed collaboration is the check-in.

Pitfall of Scrum: Focus on Scrum Tools

Learn more about transforming people, process and culture with the Real Agility Program

Many organizations try to find an electronic tool to help them manage the Scrum Process… before they even know how to do Scrum well! Use team rooms and manual and paper-based tracking for early Scrum use since it is easiest to get started. Finding a Scrum tool is usually just an obstacle to getting started.

The culture of most technology companies is to solve problems with technology. Sometimes this is good. However, it can go way overboard. Two large organizations have attempted to “go Agile” but at the same time have also attempted to “go remote”: to have everyone using electronic Scrum tools from home to work “together”. The problem with electronic Scrum tools is three-fold. They

  1. prevent the sharing of information and knowledge,
  2. reduce the fidelity of information and knowledge shared, and
  3. delay the transfer of information and knowledge.

Scrum Tools Prevent Information Sharing

Imagine you are sitting at your desk in a cubicle in an office. You have a question. It’s a simple question and you know who probably has the answer, but you also know that you can probably get away without knowing the answer. It’s non-critical. So, you think about searching the company directory for the person’s phone number and calling them up. Then you imagine having to leave a voice mail. And then you decide not to bother.

The tools have created a barrier to communicating. Information and knowledge are not shared.

Now imagine that the person who has the answer is sitting literally right next to you. You don’t have to bother with looking up their number nor actually using a phone to call. Instead, you simply speak up in a pretty normal tone of voice and ask your question. You might not even turn to look at them. And they answer.

Scrum tools are no different from these other examples of tools.  It takes much more energy and hassle to update an electronic tool with relevant, concise information… particularly if you aren’t good with writing text.  Even the very best Scrum tools should only be used for certain limited contexts.

As the Agile Manifesto says: “The most effective means of conveying information to and within a team is face-to-face communication.”

Scrum Tools Reduce Information Fidelity

How many times have you experienced this? You send an email and the recipient completely misunderstands you or takes it the wrong way. You are on a conference call and everyone leaves the call with a completely different concept of what the conversation was about. You read some documentation and discover that the documentation is out of date or downright incorrect. You are using video conferencing and its impossible to have an important side conversation with someone so you resort to trying to send text messages which don’t arrive on time to be relevant. You put a transcript of a phone call in your backlog tracking tool but you make a typo that changes the meaning.

The tools have reduced the fidelity of the communication. Information and knowledge are incorrect or limited.

Again, think about the difference between using all these tools and what the same scenarios would be like if you were sitting right beside the right people.  If you use Scrum tools such as Jira, Rally* or any of the others, you will have experienced this problem.  The information that gets forced into the tools is a sad shadow of the full information that could or should be shared.

As the Agile Manifesto says: “we have come to value: individuals and interactions over processes and tools.”

Scrum Tools Delay Information Transfer

Even if a person uses a tool and even if it is at the right level of fidelity for the information or knowledge to be communicated, it is still common that electronic tools delay the transfer of that information. This is obvious in the case of asynchronous tools such as email, text messages, voice mail, document repositories, content management systems, and version control. The delay in transfer is sometimes acceptable, but often it causes problems. Suppose you take the transcript of a conversation with a user and add it into your backlog tracking tool as a note. The Scrum Team works on the backlog item but fails to see the note until after they have gone in the wrong direction. You assumed they would see it (you put it in there), but they assumed that you would tell them more directly about anything important. Whoops. Now the team has to go back and change a bunch of stuff.

The Scrum tools have delayed the communication. Information and knowledge are being passed along, but not in a timely manner.

For the third time, think about how these delays would be avoided if everyone was in a room together having those direct, timely conversations.

As the Agile Manifesto says: “Business people and developers must work together daily throughout the project.”

Alternatives to Scrum Tools

Working in a team room with all the members of the Scrum Team present is the most effective means of improving communication. There are many photos available of good team rooms. To maximize communication, have everyone facing each other boardroom-style. Provide spacious walls and large whiteboards. Close the room off from other people in the organization. Provide natural light to keep people happy. And make sure that everyone in the room is working on the same thing! Using Scrum tools to replace a team room is a common Scrum pitfall.

Scrum Tools - Labelled Team Room Photo

The most common approach to helping a team track and report its work is to use a physical “Kanban” board. This is usually done on a wall in which space is divided into columns representing (at least) the steps of “to do”, “in progress” and “done”. On the board, all the work is represented as note cards each with a separate piece of work. The note cards are moved by the people who do the work. The board therefore represents the current state of all the work in an easy-to-interpret visual way. Using a tool to replace a task board is another variant of this common Scrum pitfall.

Updated: Agile Estimation with the Bucket System

Agile Estimation with the Bucket System

Learn more about transforming people, process and culture with the Real Agility Program

Estimation – The Bucket System [pdf] – printable reference version of this article.

The “Bucket System” is a way to do estimation of large numbers of items with a small to medium sized group of people, and to do it quickly.  The Bucket System has the following qualities which make it particularly suitable for use in Agile environments:

  • It’s fast!  A couple hundred items can be estimated in as little time as one hour.
  • It’s collaborative.  Everyone in a group participates roughly equally.
  • It provides relative results not absolute estimates (points vs. hours).
  • The results are not traceable to individuals and so it encourages group accountability.
  • Works with teams to estimate effort or with stakeholders to estimate value.


The Bucket System of estimation works as follows:

  1. Set up the physical environment as per the diagram below.  Ensure that all the items to be estimated are written on cards.
  2. Choose an item at random from the collection.  Read it to the group.  Place it in the “8” bucket.  This item is our first reference item.
  3. Choose another item at random from the collection.  Read it to the group.  The group discusses its relative position on the scale.  Once consensus has been reached, put the item in the appropriate bucket.
  4. Choose a third item at random and, after discussion and consensus is reached, place it in the appropriate bucket.
  5. If the random items have clearly skewed the scale towards one end or the other, re-scale the items (e.g. if the first item is actually very small and should be in the “1” bucket).
  6. Divide and conquer.  Allocate all the remaining items equally to all the participants.  Each participant places items on the scale without discussion with other participants.   If a person has an item that they truly do not understand, then that item can be offered to someone else.
  7. Sanity check!  Everyone quietly reviews the items on the scale.  If a participant finds an item that they believe is out of place, they are welcome to bring it to the attention of the group.  The group then discusses it until consensus is reached and it is placed in one of the buckets.
  8. Write the bucket numbers on the cards so that the estimates are recorded.

Bucket SystemSome important points to consider:

  • Multiple items can be in the same bucket.
  • Items cannot be placed “between” buckets to represent a more precise estimate.
  • If the distribution of the items is skewed to either end of the scale, then during the sanity check step the group should also discuss if the items can and should be spread out more evenly along the scale.  If so, then the group does it collectively.
  • The facilitator should watch to make sure that no one moves items that have already been placed until the “sanity check” step.
  • The division of items among participants does not need to be exactly equal – don’t worry about “dealing” out the items.  Instead, just divide them up roughly.
  • If the “divide and conquer” stage has one or two people working very slowly through their items, it is acceptable to suggest that they share their remaining items with people who are already finished.
  • It is not acceptable for an individual to completely abstain from the process.  If someone desires to abstain, they should be counselled that this means they will not have any future say in the estimates.
  • During the “divide and conquer” stage it is critical that absolute silence is maintained.  In particular, there should be no bilateral discussion of items.  This is to protect the anonymity of individuals placing items as much as possible.

The Bucket System


The bucket system is a good alternative estimation method to try instead of Planning Poker.  It is much faster than Planning Poker and still gets reasonable results.

The Planning Game – An Estimation Method for Agile Teams

Learn more about transforming people, process and culture with the Real Agility Program

The Planning Game [PDF] – printable reference.

Purpose: estimate the effort for User Stories (Product Backlog Items, Value Drivers)

Prerequisites: all items have a value estimate, each item is written on a separate note card, full team membership is known and available for planning, each team member has a set of planning game cards


  1. The team goes through all the items and chooses the one which has the lowest effort. Write the number “2” on this card (usually in the bottom right corner).
  2. The team looks at the item with the highest value.
  3. Each team member thinks about how much effort the team will expend to fully complete all the work for the item. Comparing this work to the work effort for the smallest item, each team member selects a card that represents this relative effort. For example, if you think that it requires ten times the effort, you would select the “20” card. It is not permissible to select two cards.
  4. Each team member places their selected card, face down, on the table. Once all team members have done this, turn the cards over.
  5. If all team members show the same value, then write the value on the item and go back to step three for the next item. (Or if there are no more items, then the process is complete.)
  6. The person with the highest and the lowest value cards both briefly explain why they voted the way they did. If there is a Product Owner present, this person can add any clarifications about the item.
  7. For any given item, if a person is highest or lowest more than once, then each explanation must include new information or reasoning.
  8. Once explanations are complete, the team members collect their cards and go back to step three.

– it is extremely important that the voting for an item continues until all team members unanimously vote the same way (this way team members and outside stakeholders cannot blame any individual for “wrong” estimates)
– in Scrum, it is normal for the Product Owner to be present during this process, but not to participate in the voting
– in OpenAgile, it is acceptable for people serving as Growth Facilitators for a team to participate in the voting
– voting should not include extensive discussion
– if more than one person has the lowest or highest vote, usually just one person shares their reason in order to help the process move quickly
– the first few items will often take 10 or 15 rounds of voting before the team arrives at a unanimous vote
– later on, items may take just one or two rounds of voting to arrive at a unanimous decision
– some teams, where trust levels are high, will discard with the use of physical cards and just briefly discuss votes

The planning game is used at the start of a project with the full list of user stories. In this case, it is reasonable to expect the team to average two minutes per user story, and an appropriate amount of time needs to be set aside to accommodate going through the whole list.

The Planning Game is also used any time that there is a change in the list of user stories: re-ordering, adding or removing user stories, or changes to a single user story. When such a change happens, the team can re-estimate any user story in the whole list. When starting a Cycle or Sprint or Iteration, all the user stories in the list should have up-to-date estimates so that estimation work is avoided in the Cycle planning meeting.

Finally, the team can decide to re-estimate any user stories at any time for any reason. However, it is important for team members to remember that estimation is non-value-added work and the time spent on it should be minimized.

NOTE: The Planning Game is described as Planning Poker on wikipedia.  The version described there has some minor variations from this version.

A closely related method of Agile Estimation is the Bucket System.
