“How do you {start a project} and achieve
flexibility at the beginning?”
Keep it simple
Defer commitment
Inspect and adapt
It depends

Discuss the problem
The problem:
“A program to assign a worker to a client”
The problem:
“A program to assign a worker to a client”
(yes, it’s unclear!)
Form groups of 3 (or 2)
You will have five minutes to discuss
For some user/stakeholder
Who wants to achive some goal
The name of the system
Is a type of system
Which lets them perform some operation(s).
Unlike most compelling alternative
This gives them some advantages.
For workers
Who wants to get paid for good fun work
The Awesome work system
Is a digitial pimping system
Which matchers worker with a client.
Unlike the Excel file we’re using now
This automateted, online, easy to use and .
Who?
Who?# Clients do ??? every ??? via ???
# Dispatchers do ??? every ??? via ???
# Workers do ??? every ??? via ???
# Building Managers do ??? every ??? via ???
Who?Tens of Clients sign up for service a few times every year
via meetings
Around 20 Dispatchers assign worker teams to maintainance tasks all the time via specialized application
Several hundred Workers accept tasks and confirm tasks a few times per day via mobile
Hundreds of Building Managers order maintenance tasks for their buildings every few days via web
Who else?Payroll
Describe the usage
1. Need: Someone identifies a need
2. Trigger: Someone does something with the system
3. The system responds in some way
4. …
5. …
6. The goal has been fulfilled
1. Building manager has works that needs done (e.g. change mats)1. Alternative: Periodic trigger
2. Building manager register works request on web site
3. Dispatcher lists unhandled work orders1. Alternative: Dispatcher filters, searches and sorts work orders
4. Dispatcher displays work order
5. Dispatcher assign tasks to workers based on skills registered in training system
6. Worker get notified of task on their mobile
7. Worker acknowledges task1. Alternative: If worker rejects task, system marks it as unassigned and
alerts dispatcher
8. Worker performs task
9. Worker registers the task as done
10. Worker registers time and materials spent on task on mobile
11. System notifies payroll of time spent
12. System submits invoicing data to accounting system
13. Building is in great shape!

Pick the technologies
Constraints:• Interact per user
• Portability• Supported platform
Example:• Dispatcher: ____
• Building manager: ____• Worker: ____
• Supported platform: Java stack
Example:• Dispatcher: Web or desktop
• Building manager: Web or any mobile• Worker: Provided mobile
• Supported platform: Java stack
Example:• Dispatcher: “HTML5”
• Building manager: Responsive web• Worker: Android
• Supported platform: Java stack
Example:• Dispatcher: Responsive web SPA
• Building manager: Responsive web SPA
• Worker: Responsive web SPA
• Supported platform: Java stack
Frameworks:• What can the team support
• Max one: Project risk or tech risk
Example risky project:• New team
• New supplier• New domain
• New codebase
Example risky tech:• New database system
• New framework• New programming

Plan the show
1. Building manager has works that needs done (e.g. change mats)1. Alternative: Periodic trigger

4. Dispatcher displays work order
5. Dispatcher assign tasks to workers based on skills registered in training system
6. Worker get notified of task on their mobile

8. Worker performs task
9. Worker registers the task as done
10. Worker registers time and materials spent on task on mobile
11. System notifies payroll of time spent
12. System submits invoicing data to accounting system
13. Building is in great shape!
Stories
0. (Mock work orders)
1. Complete list of work orders
2. Simple work order filter
3. Placeholder display work order
4. Placeholder assign task
Demo script
1. Preconditions
2. Start up the system
3. What do you see?
4. Activate a function
5. What do you see?
6. Activate variations of function
7. Thus we demonstrate that we have delivered x
Example: Dispatch a task
1. Faked: Building manager registers a work order
2. Dispatcher “logs into” web admin at http://test.workers.com/admin
3. Dispatcher sees a list of missions (future: sort, filter list)
4. Dispatcher selects a mission
5. Mission will display the type of tasks associated with the mission type
6. Dispatcher clicks a task
7. Application lists all the workers that can be assigned to the task (for now, all workers are listed)
8. Dispatcher selects a worker
9. Dispatcher is returned to mission screen and the worker is listed next to the task
Stories – sprint 2
1. Polished list of work orders
2. Complete display work order
3. (Placeholder worker import)
4. Simple assign task
Create the software
Example:• Feature: Dispatch task
• New codebase• 5 developers
Solo programming
Solo programming• Integration issues
• Inconsistent coding• Merge conflicts
Mob programming
Pair programming
Resource utilization

Knowledge sharing
5 tools
1. Discuss the problem
2. Describe the usage
3. Pick the technologies
4. Plan the show
5. Create the software
1. Describe stakeholders
2. Usage flow => context diagram
3. Use technologies you know
4. Demo script
5. Mob programming
Conclusion:
When you return:Create a elevator pitchwith your
customerCreate a context diagram
Create a demo script for next sprint
