Project Concerns #1

Topic	Suffering	Prognosis
Inertia	App worked fine for decades. Why change it?	Vastly superior UX and lower maintenance / upgrade costs
Resource Availability	We're all super busy and the developer quit in 1999.	Code review + carefully planned video interviews for minimal customer impact

Project Concerns #2

Topic	Suffering	Prognosis
Scope Uncertainty	The complexity will cost us and take	Phase 0 estimation + regular (functional) deliveries
House of Cards	Our data is sensitive, our infrastructure is brittle - systems access is difficult to obtain	Deliver offsite with sample data, deploy onsite to new environment

Documentation

Continuously delivered - NOT at the end of the project

• User Guide
• Admin Guide
• Developer Guide
• SAS Docs (SASjsDoc)
• JS Docs (TypeDoc)

End Result

A user-friendly, accessible, modern UI that can:

• run on both Viya and EBI
• be maintained by generic frontend / backend developers
• be maintained by the client, or any vendor (not just 4GL Apps)

Tools

• SASjs (DevOps for SAS)
• Data Controller (controlled data ingestion)
  • Resulted in a 30% cost saving (~3 months) on DWP project
• SCL Transcoding Kit (re-use of SCL logic, where necessary)
