Presentation Focus
This presentation will focus on largeutility companies, but is applicable
to any size utility
Also, the challenges inherent in implementing are similar to those
inherent in upgrading

Success Requirements
What is a successful implementation project?On scheduleOn budgetMeets business requirements
If you want a successful project:Set a realistic schedule and meet each milestoneSet an adequate scope and contain itGet resource commitments from Business and ITEstablish a collaborative team environment

Top Project Killers
1. Changing requirements2. Overly aggressive schedule3. Inadequate testing4. Inadequate user training5. Lack of corporate support6. Core team changes
It’s about managing expectations and risk.

Expectation Management
User expectationsFasterMore stableMore functionalityIntuitive and easy to useNot too different
Business expectationsCheaper to operateCheaper to maintainOn schedule and budget
It’s the game of expectation managementMake sure you understand the project drivers

Controlling Expectations
Per Building Your ArcFM:1. Expose the technology early and often to both
users and management2. Involve key users in the Core Team to build
internal advocates3. Don’t give the technology to users until they are
ready for it, and vice versa
Also establish a Steering Committee – your information conduit upwards
![Page 12: Successful Large Utility GIS Implementations](https://reader033.vdocument.in/reader033/viewer/2022051315/627a9d9158232608082b2cc7/html5/thumbnails/12.jpg)
Methodology & Risk Mitigation
1. Gap Analysis2. Data Migration3. Collaborative Design, Programming,
Configuration, and Testing4. Version Schemes and Version Maintenance5. Strategies for Successful Training, Deployment,
and Post-Deployment Support6. Performance
![Page 13: Successful Large Utility GIS Implementations](https://reader033.vdocument.in/reader033/viewer/2022051315/627a9d9158232608082b2cc7/html5/thumbnails/13.jpg)
Gap Analysis
Answers the question: What do you need the product to do that it can’t do out of the boxYou may need to think creatively; sometimes a small change in the business requirement or workflow can reduce customizationBring in users who are familiar with the current system as SME’sLook at the application’s What’s New (upgrades)Develop a list of likes and dislikes of the current system and prioritize this listThis will help define expectations that lead to requirements
![Page 14: Successful Large Utility GIS Implementations](https://reader033.vdocument.in/reader033/viewer/2022051315/627a9d9158232608082b2cc7/html5/thumbnails/14.jpg)
Data Conversion/Migration
Focus on careful data modeling and build in multiple migration iterations and QC checksAvoid changing the data model late in the gameUse SQL queries for feature counts and attribute checksTrack and manage data model changes closely, changes will impact migration and configuration

Collaboration
All design and testing must be collaborativeProgramming and configuration may be collaborative as wellChallenges of collaborative programming
Error handlingBase class utilizationTechnical supportIt isn’t easy, it adds risk, and it may end up being more expensive
The benefit is that the utility builds experience in customization, troubleshooting, and maintenance
![Page 17: Successful Large Utility GIS Implementations](https://reader033.vdocument.in/reader033/viewer/2022051315/627a9d9158232608082b2cc7/html5/thumbnails/17.jpg)
Collaboration
For collaborative programming and configuration:Make sure your programmers and configurers are properly trainedEstablish standard error handling and class utilization techniquesEstablish a vehicle for technical supportTry to be more than one deepThe more collaboration and customization, the more testing requiredFor maintenance, plan for a knowledge transfer and a support periodProvide access to Development environment via VPN or Webex Access Anywhere

Testing
Conduct a daily wrap-upHave clearly defined acceptance criteriaDefine your P1, P2, and P3 categoriesUse an issue tracking system – BugzillaBugzilla becomes a knowledge baseFor PPL, we tracked 1514 issues; issues included bugs, enhancements, tasks, training issues, etc.Stress-test yoursystem via formalstress tests andduring training

Testing
Where do you test – Factory or Site?All tests at client site – Pros
Essential with interfaces for end-to-end testingKnowledge transfer starts earlierErrors in Test Procedures caught earlierMore time for Change Requests
All tests at client site – ConsFirst round of testing can be ugly
The terms FAT and SAT don’t fit – try“Integrated Testing”

Reconcile and Posting Services
Good opportunity for labor and cost savingsBatch Post
No need to tie up ArcFM while the user waits for their version to reconcile/postVersions in conflict are bypassed
Batch ReconcileRun at night and on weekends (multiple services)Compress afterwardsKeeps the state tree shorter and improves performance
Conflict FiltersAutomatically accept the parent, but log the results (via XML) for next-day resolutionLook at the benefits of more advanced conflict filtering

Training
Design: Train the Core TeamDeploy: Train-the-TrainerGet your trainers involved in the Design and Testing processTesting is a form of training, but it can be a little rough; manage expectationsProvide Just-in-Time trainingProvide a “sandbox” environment for users to play in
![Page 24: Successful Large Utility GIS Implementations](https://reader033.vdocument.in/reader033/viewer/2022051315/627a9d9158232608082b2cc7/html5/thumbnails/24.jpg)
Deployment
Have a Cutover Plan and practice itHost an open house and/or demos to the fieldDo a pilot, then adjust trainingHave work ready for users – backlogCarefully control scopeSet up your help deskEstablish on-site front-line support (former testers) to fortify your help deskThrow a great party
![Page 25: Successful Large Utility GIS Implementations](https://reader033.vdocument.in/reader033/viewer/2022051315/627a9d9158232608082b2cc7/html5/thumbnails/25.jpg)
Post-Deployment Support
Users are going to try things that you never suspected – set a standard normal.mxt and lock itHave internal resources available for troubleshootingHave a contract vehicle in place for post-deployment supportProvide follow-on training opportunitiesEstablish a user committee and look for more quick wins

1. Set reasonable scale suppression for all feature classes within the stored display.
2. Include all related features and objects. If the related item is in the stored display ArcMap has the information local and does not need to continually go back to the database to retrieve it.
3. Avoid joins and relates.4. Avoid halos and masks.5. Avoid definition queries (if possible).6. Include network junctions and all features participating in the
geometric network if the stored display will be used for editingfeatures that participate in the geometric network.
7. Remove any unnecessary feature classes from the stored display. Organize stored displays based on the type of work being accomplished.
8. Avoid intermediate tables in 1:1 and 1:M relationships; instead,store the foreign key in the child/destination object class.
Optimizing Stored Displays for Performance
![Page 29: Successful Large Utility GIS Implementations](https://reader033.vdocument.in/reader033/viewer/2022051315/627a9d9158232608082b2cc7/html5/thumbnails/29.jpg)
1. Organize the stored display in the following order (from top to bottom): annotation, point features, lines, then polygons
2. Use Group Layers to logically group layers to allow users to easily turn on and off groups of data.
3. Alphabetize layers within group layers and after organizing by anno, point, line, and polygon features. This will make it much easier and faster for users to find layers.
4. Reorder attributes (via ArcCatalog): move required attributes upto the top, and group attributes logically.
5. Rename the data frame to match the name of the stored display. This makes it easy to see which stored display you are in.
6. Make landbase layers unselectable in the Selection Tab of the Table of Contents for stored displays that will not be used for landbase edits. This helps prevent inadvertent moving and deleting of landbase layers.
Optimizing Stored Displays for Usability

Conclusion
Work to understand and manage expectationsUse the 3D methodology and don’t cut corners. Every $1 spent in design = $100 in development.Monitor top management support for the project, and keep management appraised frequentlyKnow the strengths & weaknesses of your team; leverage the strengths, mitigate the weaknessesEstablish a collaborative team environmentSet a realistic schedule and keep itSet an adequate scope and contain itGet resource commitments from Business and IT
