1 How to Collect and Manage Requirements for Successful GIS Projects Matt Harman Mirjam Stadelmann

2 Requirements Provide direction for program success

3 Why Requirements are Important? Early mistakes lead to costly fixes

4 Build for Value Requirements evolve over time Never 45% Always 7% Often 13% Sometimes 16% 20% - Often or Always Rarely 19% 64% - Rarely or Never Standish Group Study Reported at XP2002 by Jim Johnson, Chairman

5 Where do Requirements fit? Waterfall implementation Hours Months

6 Where do Requirements fit? Agile implementation

8 Types of Requirements Business, Functional/Technical, COTS Business Meet Goals Derive Benefits What Benefits? Increase Productivity Streamline Processes Reduce Costs What NOT how Clear Define workflow Testable Functional What? Quality of Service How Well? What Constraints? Performance Usability Quality Operational Standards Infrastructure Solution Concept Leverage COTS components

9 So how do you get there. Discuss similar industries Assess business workflows Prioritize workflows Add Details Create a plan Conduct kickoff meeting Implementing an Enterprise GIS Project 9

10 Kickoff meeting Bring everyone together Executive leadership important Why is it important to your organization Provide timeline and structure Break into smaller working groups 10

11 Approach and Agenda Kickoff meeting Discuss Introductions and overview Organizations in similar industries Smaller working groups Assess Prioritize Business functions and workflows Workflows that could benefit from location information Prioritize workflows Summarize Business People Discuss next steps 11

12 Similar industries what are the GIS Patterns that apply Location Enablement Constituent Engagement Decision Support Field Mobility Analytics Location Data Management Discover, use, make, and share maps at work -- anywhere, anytime Facilitate and manage communication with stakeholders Inform execs and management with maps and location intelligence Get authoritative information into and out of the field Describe, predict, and improve business performance Collect and organize location data about your assets and resources System of Engagement (Demand) System of Record (Supply) platform/architecting-the-arcgis-platform 12

14 How to collect business needs Key business units 5-10 staff in each working group Look at your org chart Who are the primary users What are their business needs 14

15 Organization overview Organization Business Area 1 Business Area 2 Business Function 1 Business Function 2 Business Function 3 15

16 Focus on the business workflow Replacing Existing System What are the priorities Creating New Opportunity Who are the Users What Value are you adding 16

17 Workflows Incorporating Location Information Business Area: [Insert Business Area Here] Current or new workflow Use of location information What's the business value? Priority High Medium Low 17

18 Water Department Business Area: Water Dept. Current or new workflow Use of location information What's the business value? Priority Map of assets by type Improve the maintenance Color assets by last maintenance program and better manage Locate water dept. assets in the field datel financial needs Low Map of assets by type Reduce water waste Location of leaks, service calls Reduce infrastructure damage Manage water leaks Identify Properties in Service Area Not Connected to System Coordinate sampling program Workflows Incorporating Location Information Map showing pipe segments affected by leak (upstream, downstream) Location of field crews Customer locations (addresses, service, meter ) Create a map of properties and color by usage Identify sample location on map - color by sample type Improve service request response time Improve budgeting of infrastructure projects Preventive maintenance Potential additional revenue stream Improve the sampling rate by getting better coverage across county High Medium Low 18

19 So what should be in your GIS Plan? Vision statement Key workflows Approach lifecycle, budget and staffing Key things you need from the rest of the organization Schedule overview of key milestone target dates Assumptions, dependencies and risks Appendices WBS, roles, key points of contact etc. 19

20 Requirements and Analysis You have a set of preliminary workflows Analyze and flesh out requirements What information is not clear? 20

21 Next Steps How to add details to your business requirements Evolutionary Refinement of Requirements Product Backlog Requirements Who is it for? What is the result? Why is it needed? User Story #2 User Story #3 User Story #1 Daily Review Sprint Cycle <30 Days Sprint Plan/Backlog Tasks Working Increment

22 User Story Simple, brief descriptions of functionality Primarily from a user (role) perspective Sized for planning Testable Why?

23 As a [role], I can [feature] so that [reason]

24 Field Worker Real Estate Manager Public Citizen Data Provider Analyst

25 User Stories Simple and concise

26 User stories facilitate a conversation with the team Product Owner Development Lead Stakeholders The team

27 User Stories Progressively decompose your stories

28 Example Leak Management Isolation Trace Decomposing work into manageable pieces Use Cases Most Detailed Test Case Titles Locate by address User Story Locate Leak Locate with Map As a Field Engineer I need to run an Isolation Trace to identify network leaks, and improve the quality of water service to all customers. Pick Trace Starting Point Run Trace Configure Options Execute Trace Select from map Field Crew Launch Mobile App Locate Leak Run Isolation Trace Notify Customers Fix Leak Display Trace Results Save Trace Trace Map Summary Report Detail Report 28

29 User Stories Consider grouping them into themes

30 Not always about [a user] Capture key concepts

31 Use Paper Cards Keep them simple and concise

32 Keep user stories visible Focus of daily meetings

33 Requirement Management Tools Licensed and Open Source Compare Microsoft Team Foundation Server (TFS) Waffle.io JIRA

34 Requirements Process Things to avoid Avoid long lists of requirements Do not be judgmental Prepare for conflicting requirements Avoid requirements that are ambiguous Avoid requirements that describe HOW (unless you are using COTS approach) Don t forget to prioritize Requirements must have a reason

35 Requirements THE most important part of a project Solid requirements gathering leads to successful projects Consider solution, COTS capabilities before collecting additional requirements Involve the right people in the process Pick a methodology that fits your project Focus on the level of detail that is appropriate Important to prioritize and allocate Invest plenty of time to secure customer approval
