This talk is about

What’s this thing we are building?

Use that understanding to plan the work

A simple way to measure progress

(that works just as poorly, but is simpler)

After this talk

Uncover what needs to be done

Forecast from actual progress

Plan ourself out of the rush

But first

Where does the rush come from?

Part I

The worst way to answer: To estimate

hours per task

Actual hours =

Σ estimated hours per task * “load factor” * “management overhead” * fudge factor

Actual hours =

Σ estimated hours per task * whatever

Part II

Creating the backlog

• Vision• Usage flow

• Product backlog

Vision, stakeholder

For some stakeholderWho wants achieve some goal

The ??? system Is a type of application

Which lets them perform some actions.

Unlike most relevant alternativeOur product has some advantage

For company employees

Who wants to take leave from work

The Leave-IT system

Is a responsive web application

Which lets them register leave applications and get them approved

Unlike sending emailsOur product lets them keep track of leave days

available and team leaves

Employee

Team lead

Leave-IT

Usage flow

1. HR admin logs in via SSO (same for the other stakeholders)

2. HR admin navigates to Leave-IT

3. HR admin allocates leave quotas based on information in HR database

4. HR admin builds company calendar

5. HR admin adjusts the leave quota for an individual user in HR system

6. HR admin assigns leave approvers from uses in HR system

7. Employee views their available leave

8. Employee submits leave request

9. Leave-IT notifies Team leader of a new pending leave request via email

10. Team leader views pending leave applications

11. Team leader checks the other leaves in the same time period

12. Team leader approves leave

13. Leave-IT notifies Employee of an update of his leave request via email

14. Employee checks status of own leave application

15. Employee cancels own leave

16. PMO views the teams' leave calendar, plans and history

17. PMO may cancel leave if necessary

14. Employee checks status of own leave application

15. Employee cancels own leave

16. PMO views the teams' leave calendar, plans and history

17. PMO may cancel leave if necessary

Product backlog

1. Experimental submit leave

2. Experimental show leave status

3. Simplified layout and style

4. Simplified approve leave

5. Simplified view leave request

6. Simplified submit leave

(content)

Experimental submit leave request

1.Go to the front page2.See that there is a dropdown with possible users and

approvers3.Select a user, approver, start date, end date, reason4.See that the number of days is updated5.Click submit6.See that the data is in the database7.Submit a request with no start or end date8.See that there is an error message9.See that the data is not in the database

Log in using Exilesoft SSO (foreign user story from SSO)

1.Open a new web browser and go to the application2.Verify that the user is not logged in3.Click login4.The user is sent to Exilesoft SSO5.Verify that the username is correct when the user is

returned to applicationTODO• SSO must support cross-domain authentication

1.Delete any existing permission from https://security.google.com/settings/security/permissions

2.Open a new web browser and go to the application3.If you are logged in, click log out4.Click login5.The user is sent to Gmail to authenticate6.Deny the authentication request7.Verify that the login button is still displayed8.Click login again9.Allow the authentication request in Gmail10.Verify that the users email address is displayed11.Click log out12.Verify that user email address is no longer displayed

Thank you

• Context– “We get a tender with epics and need to give a price” (Janini, Virtusa)

– We have a team that is “confused” – beginning or halfway through

• Get a team together and discuss the who, why, what (actions) and alternatives (vision statement)• Use actions to start the discussion of the usage flow (a narrative that starts with the first

interaction with the (sub)system and ends when the business value is produced)• Create the product backlog from the usage flow. I like the items on the product backlog to be

man-week sized. Each action from the usage flow goes into the product backlog. In addition, the product backlog should contain activities for layout, deployment, specific testing etc.

– Separate different iterations on the same increment in time to accumulate feedback– Prioritize the items for the first internal demo, first external demo and first trial deployment– Simplified user stories can be used to detach teams

• This gives a list which length predicts the number of weeks. Weeks = # Items / number of item producers. Hours = Weeks * Burn rate

• Tracking– As project proceeds, track actual progress (count of items per week) versus forecasted progress. Also track changes in total

scope. This will adjust the forecasted times and costs.– Demonstrate with the customer whenever you can. This will determine if the quality matches their expectations– Deviation in progress, changes in scope or missed expectations mean you should discuss contract with customer or suffer

consequences

• Focus through demo planning– In scrum planning, when you know the scope, come up with a screenplay script for the demonstration. Get someone brave to give

a mock demonstration during the planning. => Focus on the outcomes– Use the demo focus to help the team break down technical dependencies– Practice the demo towards the end of the sprint– Give a demo like you mean it, but don’t lie (unless you want to delude the value of the feedback)

• Planning – man-week sized items– Gather “everyone” to discuss => usage flow– Usage flow actions x revisits (experimental, simplified, basic,

complete, polished), technical items (layout), releases => product backlog (releases planned in time)

• Revisits with different expectations (experimental, simplified, basic, complete, polished) – also used to avoid deps

• Technical items with visible results• Releases

– Product backlog => time and cost (t = s/v)

• Tracking every week– Actual production, changes in scope– Demonstrations with customers => expectations– Progress, scope, expectation/insufficient done-ness => risk

• Accelerating with demo– Practice mock demo during planning

• Example project: Planning Monday, Demo rehearsal Friday morning, Demo Monday morning

– Use demo driven work to focus on feature slices (avoid deps)– Demonstrate with externals to get feedback

• Planning – man-week sized items– Gather “everyone” to discuss => usage flow– Usage flow => product backlog– Product backlog => time and cost (t = s/v)

• Tracking every week– Actual production, changes in scope– Demonstrations with customers => expectations– Progress, scope, expectation/insufficient done-ness => risk

• Accelerating with demo– Practice mock demo during planning– Use demo driven work to focus on feature slices (avoid deps)– Demonstrate with externals to get feedback

• Need better example project

• (Architecture – don’t play)• Team-mbedded product management
