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/stakeholderWho wants to achive some goal

The name of the systemIs a type of system

Which lets them perform some operation(s).

Unlike most compelling alternativeThis gives them some advantages.

For workersWho wants to get paid for good fun work

The Awesome work systemIs a digitial pimping system

Which matchers worker with a client.

Unlike the Excel file we’re using nowThis 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

meetingsAround 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 mobileHundreds 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 need2. Trigger: Someone does

something with the system3. The system responds in some

way4. …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 site3. Dispatcher lists unhandled work orders

1. Alternative: Dispatcher filters, searches and sorts work orders4. Dispatcher displays work order5. Dispatcher assign tasks to workers based on skills registered in

training system6. Worker get notified of task on their mobile7. Worker acknowledges task

1. Alternative: If worker rejects task, system marks it as unassigned and alerts dispatcher

8. Worker performs task9. Worker registers the task as done10. Worker registers time and materials spent on task on mobile11. System notifies payroll of time spent12. System submits invoicing data to accounting system13. 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 language

Plan the show

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

2. Building manager register work order on web site3. Dispatcher lists unhandled work orders

1. Alternative: Dispatcher filters, searches and sorts work orders4. Dispatcher displays work order5. Dispatcher assign tasks to workers based on skills registered in

training system6. Worker get notified of task on their mobile7. Worker acknowledges task

1. Alternative: If worker rejects task, system marks it as unassigned and alerts dispatcher

8. Worker performs task9. Worker registers the task as done10. Worker registers time and materials spent on task on mobile11. System notifies payroll of time spent12. System submits invoicing data to accounting system13. Building is in great shape!

Stories0. (Mock work orders)1. Complete list of work orders2. Simple work order filter3. Placeholder display work order4. Placeholder assign task

Demo script

1. Preconditions2. Start up the system3. What do you see?4. Activate a function5. What do you see?6. Activate variations of function7. Thus we demonstrate that we have

delivered x

Example: Dispatch a task

1. Faked: Building manager registers a work order2. Dispatcher “logs into” web admin at

http://test.workers.com/admin3. Dispatcher sees a list of missions (future: sort, filter list)4. Dispatcher selects a mission5. Mission will display the type of tasks associated with the

mission type6. Dispatcher clicks a task7. Application lists all the workers that can be assigned to the task

(for now, all workers are listed)8. Dispatcher selects a worker9. Dispatcher is returned to mission screen and the worker is

listed next to the task

Stories – sprint 21. Polished list of work orders2. Complete display work order3. (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

1. Describe stakeholders2. Usage flow => context diagram3. Use technologies you know4. Demo script5. Mob programming

Conclusion:

When you return:Create a elevator pitchwith your

customerCreate a context diagram

Create a demo script for next sprint
