Hi,

Can somebody help me to know how to decide chapters of user story points in start sprint when we are just aware of the scrum team capacity in hours?

Instance:

My teams capacity for a week is 210 hrs and the estimation of all user stories is 48 user story points. At present tell me how can we make up one's mind how much user story points of piece of work nosotros can consider in first sprint? Team is completely new to Agile and we don't have any previous velocity record as well.

Please propose

Thanks

Bina, I replied to your other post that is like to this. There is no Chapters of User Story Points, yous're referring to the Velocity. There is no velocity in the kickoff dart; it'southward all guess work. Once your squad has decided upon your sprint length, your developers should be able to look at each point and have a ballpark estimate of the fourth dimension it volition take to piece of work on something. They can decide how much to choose for the dart.

No data -> make an informed guess -> execute -> inspect & arrange.

Focus on GATHERING empirical data before using it. Beginning few Sprints volition be used to gather this information. At the end of the Sprint yous will know how many story points the current team with their current level of understanding of the process and functionality tin achieve which is let united states say thirty points. So now you have some data from your first Sprint ! Your team can do 30 points / 210 hours = 1/seven points per hour or 1 indicate for every seven hours.

At present for the side by side sprint the Same team estimating the Aforementioned backlog (means aforementioned business domain and technical aspects needed) working the SAME hours (without holidays and sick leaves) will probably reach the SAME velocity right?

That means if the new bachelor hours (after bookkeeping for holidays and planned off time from squad members) is lets say but 175 hours, how many points would y'all comfortably be able to finish? one/7 X175 = 25 points. So select 25 points for the next Sprint in the planning session with the limited data you take keeping in listen to exist ready to have more than as the squad efficiency and understanding of the product and tool use increases. And permit us say you lot were actually able to achieve 28 points (more than the forecasted 25 points)

Now , based on the latest empirical data your UPDATED velocity which is more accurate and current is (30+28)/(210+175) = i/vi.6 points per hour or 1 point for every 6.six hours

So for the next Dart if you know you take 210 hours y'all know yous can comfortably pick 210(1/6.6) = 31 story points

This is how you give more than importance to observing and inspecting what is happening to predict what is going to happen. The true value of the velocity is in it's ability to help you plan better for each Sprint. With each dart the new data gives more than accuracy to your forecasts.

@ Uma-Venkata. My only consequence is y'all're calculating a constant/fixed value (hours) against an capricious/fluctuating value (story points).

That would like trying to determine how long it would have a vehicle driving 70 mph to bulldoze a few hundred miles. "Few hundred" could be 200, 350, 625, or other because it's an capricious value.

If you want to be able to use a elementary calculation like this for your planning; why even use story points? Why non just employ hours instead?

Can somebody help me to know how to decide capacity of user story points

The purpose of estimation is to help a Evolution Team to effigy out how much work information technology can take on. Story pointing is but a means to that stop.

If a Development Team has estimated conscientiously, and so squad members volition have obtained an understanding of how much work each Product Backlog item is probable to involve. That shared understanding is a more critical output of refinement than whatsoever numbers.

A team could estimate using t-shirt sizing for example. They might have no notion of story point capacity at all, but they would nonetheless appreciate the telescopic of the work they take discussed, and whether the forecast to come across the Sprint Goal would probable be achievable in the time-box. That appreciation should improve over subsequent Sprints.

06:14 am June 22, 2018

Cheers Curtis, Filip, Uma and Ian for your valuable response. Information technology volition assistance me a lot!!

1 more question related to reflection of estimation in JIRA. Suppose I have User Stories as below:

Epic1 - 8 User Stories (Add-on of userstory1 and userstory2 estimate))

 UserStory1 Under Epic1- three User Stories (Addition of Task1 and Task2 Judge)
Task1 nether User Story1 - 1 User Story Points
Task2 under User Story1 - 2 User Story Points

 UserStory2 Under Epic1- 5 User Stories (Addition of Task1 and Task2 Judge)
Task1 under User Story2 - 2 User Story Points
Task2 under User Story2 - iii User Story Points

JIRA board shows total estimate every bit 24 (eight+3+ane+ii+five+2+3) Story Points?
Withal It should testify only viii user story points since rest of the estimates break-up of the estimate for EPic1 and information technology should not add.

What tin nosotros do so that JIRA can bear witness Total sprint estimate as eight user story points and not 24 story points.

Also can we have both units available (Story points besides as hours) for tasks level estimate?
I believe tasks should be estimated in terms of hours just. Or everything should exist in terms of story points or nosotros can accept interpretation of user stories in story points and subtasks in hours?

Please let me know what should exist the exact approach.
Many thanks

What can nosotros practise then that JIRA can show Total sprint estimate every bit 8 user story points and non 24 story points.

I call up there is something off with your configuration in JIRA or how y'all setup the stories. Honestly, I'd have to look at it in order to help further.

I believe tasks should be estimated in terms of hours just.

Why? If it is strongly discouraged to estimate stories as a whole in terms of hours, wouldn't that aforementioned thought process apply to the tasks as well? What benefit would yous get from estimating the tasks in hours but the stories in story points? I would become one mode or the other for everything. I don't like estimating with hours considering at that place are e'er interruptions that take away from that fourth dimension based estimate. The other benefit of using story points is the squad can tweak and fine tune their estimations with more than flexibility to meliorate fit the team. Using hours, yous have a single variable that is fixed. 1 60 minutes will e'er be 1 hr but 3 story points can change drastically throughout the course of a team using agile thanks to the process of empiricism.

I've heard it said that information technology can exist helpful for a Evolution Team to apply hours, once they get to Sprint Planning, and are producing their Sprint Backlog.

I remember it'south important to describe a distinction between making relative estimates for the purpose of refinement, prioritization and longer term forecasting – and developers setting out how they will plan their work towards a Sprint Goal.

It's not a practise I've tried, just I see nothing wrong with a development squad choosing to exercise this. However, it actually must be the choice of the team.

To me, ane thing that seems to be disregarded in this word is that we're talking virtually estimates , which are best-guesses based on the information at hand.

What information/tools exercise nosotros have?

  • Projected available team capacity in hours (an educated guess)
  • Product Excess Items relatively sized in story points by the squad doing the work (an estimate)
  • Calculated team-velocity, if the team has completed several sprints (a adding based on empirical testify, which were derived from estimates)
  • Team member expertise

With this information, just present the "offering" to the team according to the decided Sprint Goal, and ask the team how much they feel they tin can reach according to the DoD within the given sprint time box, using the available information.

1 thing that traditional project direction gets incorrect (one of many, in my stance) is that it tries to treat estimation every bit an exact scientific discipline.   Interpretation is, by definition, non-exact .   They are aught more than guesses.

So, enquire your team to make a guess, and work with your squad to try and make better "guesses" in the future (if needed).   Don't over-complicate this.

My only issue is yous're calculating a constant/fixed value (hours) against an arbitrary/fluctuating value

Curtis, Not true. Nothing is fixed except for the UNITS! Both the story points and total number of hours are expected to change ! The but thing that is abiding is the ration (Story points/Hours). Each Dart you only calculate the full number of story points and the full number of hours (by entire squad actually billed afterwards leaves and all).

We of form measure the total fourth dimension spend per story to go an thought of what our story points ended upwards as. For example we realize that what we thought one story point actually took on an boilerplate 20 hrs and what we though three story points actually took 28 hrs (not necessarily lx). Each sprint nosotros measured this and currently our values are as follows.

1 Story point means 16 hrs based on our teams historical data (this will be different for each team)

two story points means 22 (not 32 !) based on our teams information

3 ended up existence 35 at this fourth dimension.

Again for next sprint we volition use hrs merely when needed considering we still use story points covered on an average per unit of measurement of 60 minutes to summate our velocity. We empathize that our understanding of the story point improves each sprint and our estimates become even ameliorate. Story point to measure out compared to Aforementioned team estimating the SAME backlog and so ordinarily they end up allocating like UNITS for SIMILAR Stories anyways. All you demand to do is compare these (assuming their reasoning and therefore their story bespeak estimation is commonly going to be the same) points delivered per hr for each sprint and extrapolate for future sprints.

My last response seems to be too lengthy without directly addressing your above supposition. Let me accost that here.

Yous are right that the story point is an arbitrary value, merely it is not fluctuating within the Aforementioned squad and SAME backlog. It of form can fluctuate and will exist different between two different teams.

That is why velocity is used to calculate within the team to predict its futurity performance compared to its histrocial performance.

I do not agree that the story point value fluctuates much inside the Same team working on the Aforementioned excess over time especially once the team has matured and estimating its backlog, and this is my basic supposition in relying on this method.

JIRA board shows total guess every bit 24 (8+three+1+2+5+2+3) Story Points?

Bina, JIRA sums the total points. This is what we did

  • We used story points only for Stories
  • Epics practice not have whatever measurement (We did not observe the need)
  • Tasks are estimated and measured in hours, not points. Team puts remaining hours and keep updating the actuals daily.
  • Simply show (add it to the presentation , JIRA admin work) the same time field on Story . It will prove the actuals summed for all tasks under it.
  • The same fourth dimension field ( forgot what it is, just you can inspect what you accept on story and reuse it in the presentation for Epic on JIRA ) will show the total time across all the tasks under all user stories on that epic (though nosotros never felt the need to get actuals at epic level)
  • At the end of the Dart we created an excel canvass to depict in each row (we reviewed it in retrospective), each story (ID and may be championship)- originally estimated story points - bodily hours spent , to go the value of what each story signal ended upwards. These values started getting consistent with each sprint we progressed!

08:46 am June 23, 2018

Many thanks Uma, Curty, Timeothy and Simon for your response.

@Uma, can you lot delight let me know the exact field in JIRA which automatically calculates the total estimates of user story past adding the estimation of tasks under it?

I have farther query regarding your beneath comment

  • We used story points simply for Stories
  • Epics exercise non have any measurement (We did not discover the need)
  • Tasks are estimated and measured in hours, non points. Team puts remaining hours and keep updating the actuals daily.

As per your higher up comment

Suppose I have one user story for which estimate in user stories is 2 which was decided by scrum team in dart planning meeting.

Nevertheless, suppose at that place are 2 tasks nether this user story. Estimate of one task has been provided every bit three hrs and judge of other chore has been provided as five hrs.

Then exercise yous mean we need to add some time field in user story screen where information technology will automatically reflect the full time of user story every bit (3 hrs + 5 hrs =  viii hrs)?

What about the estimate which has too updated for the aforementioned user story as 2 user story points?

Likewise how can we plot the burn down downwards nautical chart when team can't be able to provide how much user story points of work is remained? They can only update the total number of hrs piece of work they accept done and so far for detail date.

east.g. Team member  who working on above issue was just able to work for two hrs on beginning day and was non able to piece of work for the complete day. He or she tin can't estimate and will exist in position to tell how many user story points of work he or she has completed. He can only update total remaining hrs of work as vi hrs and not in terms of story points.

In such case which pick should nosotros consider in burndown nautical chart's Y axis. Is it user userstoriepoints ? Only squad member has merely updated the time worked and remaining in hrs under each tasks. Then JIRA'south burn down down chart volition reflect what? 10- Interpretation in Hrs and Y axis dates.

Suppose my target was 8 user story points of piece of work and squad has finished only ii hrs of work on offset day. Tell me can we plot a burndown chart  on JIRA since nosotros don't know how much story point of work is remaining but we know 6 hrs of piece of work is remaining. The aforementioned can be plotted if estimation of user story in hrs. due east.g. from 8 hrs of work now 6 hrs of work is remained. But having employ story judge in user story points and subtask approximate in hours will not help to prepared a burndown chart since team members will just update the reamaining work in JIRA in hrs only and non in user story points.

Many cheers.

Please confirm.

Thank you once over again for your time.

09:xiv am June 23, 2018

Continuation of above question..

Is there any site or video which can show a complete scrum procedure including estimates and different Metrics in JIRA which we can implement for our project? Sometimes I experience that Agile scrum'south theory knowledge is actually not helping 100% while implementing it in live.

due east.g. Different opinions about user story level and task level approximate process and and so confusion of preparing of burndown chart based on the different estimate units for user stories (due east.g. in Use story points) vs estimate units for associated subtasks (eastward.g. in hrs) bold team member will just update the work completed everyday in hrs at JIRA.

If there is any good video around actual practical implementation of scrum using JIRA and so please share the link.

Thanks Uma, Curty, Timeothy, Simon, Ian and Filip for your valuable time.

Bina,

Please refer here. There is a lot of documentation out there and the backend field names slightly vary based on the version of JIRA yous are using,

https://confluence.atlassian.com/jirasoftwarecloud/avant-garde-searching-f…

Look for the field called "Time Spent" on this (in a higher place link is already tabbed to that field).

you guys may likewise think about using work ratio field. the above guide clearly explains how each field works.

delight refer to this youtube video: https://world wide web.youtube.com/sentinel?5=iwfrkiiuknI&list=PLjYflIjksc6iR1eLJ-d7b2yP_UUgalckL

I strongly urge you and your team to read this commodity explaining SEVERAL best practices for estimating and tracking using JIRA fields (story points, estimate, fourth dimension spent (time log)) etc.

https://confluence.atlassian.com/jirasoftwarecloud/estimating-an-event-…

Again Gauge is "Estimate" Non supposed to be ACCURATE. My focus is always on trying to figure out what our estimates ended upwardly using existent data once the time logs the time confronting each activity or even meliorate the full time spent by the team and total points the team completed as estimated by them each sprint.

I avoid private task time logging until the squad feels comfortable and understands the purpose of measuring is to measure the TEAM'due south efficiency and non an individuals !

So do you mean we need to add some time field in user story screen where it will automatically reflect the total time of user story as (3 hrs + 5 hrs =  viii hrs)?

Yeah, there is a field that will show the estimated time in hours (based on task estimates) and the time spent (based on the task time spent full).

You are complicating this as well much. For example, your estimate of eight hrs WILL most probably end upwardly equally xiv -16 or more hours when you lot are actually washed later identifying all tasks and piece of work (that you lot initially may have missed) during your sprint piece of work. In the stop al matters is that what yous said as 2 points Really took 15 hrs !

Like I said the focus should be on LEARNING what your team's sizing concluded upwards as and then the team will get a feel of what their relative estimations mean and can judge ameliorate in future.

During refinement estimate equally many backlog items as possible in story points. Measure how many story points yous were able to complete this sprint extrapolate the graph ! Keep adjusting with new velocity data from each dart. Simple!

02:26 pm June 23, 2018

east.g. Team member  who working on higher up issue was just able to work for 2 hrs on showtime solar day and was non able to work for the consummate day. He or she can't gauge and will be in position to tell how many user story points of work he or she has completed. He can merely update total remaining hrs of piece of work as half-dozen hrs and non in terms of story points.

Micromanagement !

Only having utilise story estimate in user story points and subtask estimate in hours will not help to prepared a burndown chart since team members will just update the reamaining work in JIRA in hrs merely and not in user story points.

Why are y'all concerned well-nigh how the team estimates their work in sprint? Just measure the whole detail once its actually done. FORGET about the actual fourth dimension information technology ended upwardly. Keep this data for retrospective and so the tam will employ it for ameliorate story indicate estimation of future backlog items. This is how JIRA uses burn down charts.

https://www.atlassian.com/agile/tutorials/burndown-charts

If yous want to summate at chore level experience free to export the Totals in hours and totals spent in hours and generate a graph using time instead of story points = micromanagement according to me.

Curtis, Not true. Zilch is fixed except for the UNITS

Uma, an hour is an hour, it doesn't fluctuate, only the number of hours fluctuate. The same is not true of story points. 2 story points does not accept a fixed value. Information technology could mean x amount of work at a given time and later it could mean a completely dissimilar amount of work; even for the same team and same product. That was my point. In a mature squad, fluctuating is less likely just information technology takes many teams several months to fifty-fifty several years before they truly get a strong hold on estimation so that the story points do not fluctuate.

I concord with Tim in that doing all of these calculations against an estimate is just a scrap also much. It's a best approximate, no thing how mature or educated a team is; information technology's still an interpretation and not a stock-still value. Therefore trying to calculate it out merely seems like a waste of time.

What is the bespeak of relating Story Points to hours at all?  Why non but apply hours?

Profile picture for user Uma-Venkata Ratna-Kumar Lekkala

02:00 pm June 25, 2018

What is the point of relating Story Points to hours at all?  Why not only apply hours?

Alex, I think I sent out incorrect agreement. Our attempt is not to anticipate or judge anything in hours. We are but realizing (discovering and learning) what our story points ended up as, afterwards each sprint.  The expectation is that our agreement of what each story indicate number (i,2,3,five,.) means will gradually improve and normalize within the team though it tin can be completely dissimilar from a different team (fifty-fifty working on the same production backlog) equally each team volition has their ain understanding of these numbers and the velocities are not same for the same team size working on same excess.

The assumption for us to use this method however is that this commonage understanding will remain Abiding inside the team working on the same backlog and therefore we can PREDICT how much each team can accomplish in futurity dart compared to that squad'southward historical velocity data.

How and when we utilize the collected information: When we are nearing the cease of Sprint we use the collected averages (observed hours it took for each story signal) from the most recent sprints (two-3 , but not from the first where our team is still normalizing its understanding  of the production, tools and skills) then the type of work as non inverse much. Using this information we decide if nosotros tin can add together or drib some stories to attain the Sprint goal without pushing something one-half broiled.

When we take around 3 days left (108 dev hours) we kind of Gauge how many stories we tin can comfortably finish based on this information. And this gauge will change for each squad based on how they are VALUING their stories collectively.

I agree with Tim in that doing all of these calculations against an estimate is but a chip also much. It'southward a best guess, no thing how mature or educated a team is; it's still an estimation and non a stock-still value. Therefore trying to calculate it out just seems like a waste of time.

True! I should not have explained our little exercise of learning what our story points ended upwardly as hours (explained why in in a higher place post). Nosotros basically use the story points (per 60 minutes) derived from our refinement sessions and try to estimate how much we can do in each sprint knowing that our estimates will be less fluctuating as we progress similar y'all just explained above. The calculation I posted in my first post is yet the way we guess. Based on how many point we did in how many hours (points/hr) which is the constant we want to encounter or improve, we will estimate how many pints we can do in side by side sprint which is

Points estimated = velocity Ten (hrs available in next sprint)

02:fifteen pm June 25, 2018

While calculating velocity (if you are decided to utilise it) does any i consider the number of hours in their calculation?

For example if half of the team is off for some reason for the adjacent sprint and the number of story points delivered were twenty instead of 40, would y'all consider the velocity as the same or different?

My starting time postal service is just addressing this and we are doing pretty skillful forecasting how much nosotros can exercise and meeting what nosotros forecasted without stressing too much. I might have explained this with likewise many numbers/examples, only the idea is pretty uncomplicated.

Points per Hours and NOT Points per Sprint.

I suppose in that location is some benefit (as outlined past Uma) to mensurate the actual time a PBI took, to requite the team some insight into the accuracy of their estimating.   However, I yet maintain that much of the fourth dimension-based estimation and measurement is not needed, and is wasteful effort.   Just because a tool provides a capability, does not hateful that it must be used.   ;-)

This is my arroyo with my teams, and it has worked very well for me and the teams I serve:

  • People naturally gravitate to rating things across a 5-value range.   A smaller range does not provide enough options, and a larger range makes it more difficult to differentiate existent value differences
  • Case in point: think of the terminal time that yous were asked to rate something on a 10-calibration.   Did you clearly know what the difference was betwixt a 6 rating and a 7 rating, or a 2 rating versus a three rating?   Retrieve of the times you lot were asked to rate something from ane-5 stars.   Would your task have been easier if you had more or less stars to rate with?
  • When asking teams to relatively estimate, yous're really but asking them to categorize items into one of 5 categories (extra small, pocket-sized, medium, large, extra-large).   Whether they prefer to use story points, or t-shirt sizes, or any other method (animals, cars, etc), they're simply placing items into one of v categories of size
  • A side-benefit to teams naturally gravitating to using a 5-scale is that information technology may exist possible to normalize estimates at a plan level, even when teams are using different terms or values (1-2-three-five-viii, 5-eight-thirteen-21-34, etc)
  • I accept asked teams to create tasks for items, as it helps with detail understanding, but I practice not ask teams to provide any fourth dimension-based guess for those tasks.   In my stance, the value around task-based time estimates is not supported past the effort needed to develop and track them
  • And that'due south it.   Lightweight and elementary.   The accuracy using this method is acceptable (and improves over time), and there actually isn't much ROI returned asking teams to provide more granularity or particular
  • Also, I practise ask my teams to consider their chapters each dart during Sprint Planning, as their availability may dictate how many story points are comfortable for the team to forecast.   Again, in my stance, this lightweight approach is preferable to performing calculations in an endeavor to promote "carefulness" with team interpretation

Signal noted. We actually need to finish over engineering this estimation I judge !

05:26 pm June 29, 2018

@Uma. I have gone through the video links which were very helpful to me at least start with some base. Because estimation topic is always disruptive due to below probabilities was non able to sympathize exactly which is ameliorate and why?

I simply saw that multiple discussions were happened after my last annotate.

I am trying to clarifying my understanding once again.

What I have started to follow is estimating the user stories in user story points but the subtask will be in hours. Do we even need to guess subtasks equally well in user story points?

Addition of total hours of subtasks in hrs helps me to justify the capacity of user story points which we tin pickup for first sprint

east.m.

User story one - Story Points -three

                                    Subtask1 associated with user story 1 -> 12hrs

                                    Subtask2 associated with user story i-> 15 hrs

User Story ii- Story Points -5

                                Subtask1 associated with user story 2 -> 15 hrs

                                 Subtask2 associated with user story two -> xix hrs

User Story 3- Story Points -8

                                Subtask1 associated with user story 2 -> 20 hrs

                                 Subtask2 associated with user story 2 -> 22 hrs

   So it helps me to understand total number of hrs required to complete two user stories which is (12+15+15+nineteen+20+22=103 hrs)

Now assume that my weekly chapters of seven squad members with only 2 potential hrs per day is 7*2*five=70 and I have one week dart.

Then it will aid me to empathise which user stories which we can pick-up.

e.g. Since I have capacity of only 70 hrs then I will merely consider user story one and user story 3 (27 hrs+42 hrs=69 hrs)

and my capacity is 70. This information technology helps me to empathise how much work I can pickup for the first sprint.

I tin understand and then what is the use of estimating user stories in story points since these are not helping to decide how much user stories nosotros tin can pickup based on the known capacity.

Are other colleagues saying not to estimate anything fifty-fifty subtask in hrs and we should estimates these also in user story points? Only then we demand to accept intendance that story points of particular user stories should friction match with summation of the user story points of the master user story.

And also how we tin can guess how much story signal of work we can consider since we are just aware well-nigh the total capacity in hrs merely total piece of work to be done in story points.

I guess somebody told that nosotros just need to guess something in showtime instance and information technology will be improved over the time in instance story point is the simply measure for user stories and associated subtasks.

Apologies, seems that demand to clarify my understanding once again if I am doing information technology wrongly..

Thanks

Bina,

My proposition (and my preference) is to document the sub-tasks, only not go through the added (and in my opinion unnecessary) try of sub-chore estimation in hours.

You take the relative estimate of each item.   No need to guess the sub-tasks in the hope that they will somehow always curl upwardly to a correct SP value.   If that is your idea, and then relative interpretation is a waste product under that approach.

You likewise have the calculated hour-based sprint chapters of the team.   Go a few sprints nether your belt, and evaluate how many points the team is completing each sprint, and what their hourly capacity was each sprint.

Then have the team and PO plan the next sprint, using those metrics as guidelines for how much to forecast.

To start with the start dart, just inquire the team to brand a forecast based on their all-time gauge, and go from there.

Over again, my advice is to not over-complicate it, and to care for estimates as guesses based on the data at paw.
