Who is Rijkswaterstaat (RWS)?

•  RWS is part of the Dutch Ministry of Infrastructure and Environment. •  RWS is responsible for the design, construction, management and

maintenance of the main infrastructure facilities in the Netherlands:

–  the main road network –  the main waterway network –  the main water systems

Mission: Rijkswaterstaat promotes safety, mobility and the quality of life in the Netherlands

Rijkswaterstaat 4 Low-Code Applications at RWS RWS INFORMATION -

Low-code application platforms

•  Technology for creating applications through configuration of functions, rather than coding those functions.

Shift from coding to modeling

•  RWS has selected Mendix as the agile

developmental platform. –  Agility –  Time-to-Market –  Short-lifecycle apps (PoC)

Rijkswaterstaat 5 Low-Code Applications at RWS RWS INFORMATION -

Maintenance and Control of applications: •  Directives:

–  Lifecycle management –  Technical quality –  Security –  Maintainability

•  Product quality model: ISO/IEC 25010 •  Major suppliers for ‘Making the model measurable’:

SIG, CAST, TIOBE

Rijkswaterstaat 6 Low-Code Applications at RWS RWS INFORMATION -

SIG at RWS

•  Contract for quality check code customized applications

SIG works with our validation and verification department (CIVVV) to check the code of customized applications

•  Mendix uses a cloud service to perform a static analysis of Mendix application models: Mendix Application Quality Monitor (AQM)

Rijkswaterstaat 7 Low-Code Applications at RWS RWS INFORMATION -

AQM Mendix applications

•  Code quality rating (maintainability)

Rijkswaterstaat 8 Low-Code Applications at RWS RWS INFORMATION -

Quality Gates (metrics) at RWS - I

•  Quality control of the application code –  Duplication of code –  Size of the modules –  Complexity

•  Composition of the Apps –  How many modules –  Type of modules –  Circular dependencies

Rijkswaterstaat 9 Low-Code Applications at RWS RWS INFORMATION -

Quality Gates (metrics) at RWS - II

•  Connections –  Inter-App connections –  Database connections –  File connections

•  Security –  Internet/Intranet connection –  Malware, Backdoors, Trojans, Viruses, Worms, etc.

Rijkswaterstaat 10 Low-Code Applications at RWS RWS INFORMATION -

AQM/SIG Monitor -I

•  Duplication

Rijkswaterstaat 11 Low-Code Applications at RWS RWS INFORMATION -

AQM/SIG Monitor -II

•  Architecture / Dependency graph

Rijkswaterstaat 12 Low-Code Applications at RWS RWS INFORMATION -

AQM/SIG Monitor -III

•  Technology distribution

Rijkswaterstaat 13 Low-Code Applications at RWS RWS INFORMATION -

Summary

•  Low-code applications have a short building time •  Low-code applications can be deployed easily on our PaaS •  Low-code applications are cloud aware

•  SIG rating is a factor for maintainability, but not for deployment.

•  Use Technology distribution, duplication, dependencies •  Limit the use of modules in an App •  AQM/SIG Monitors gives us better insight in the Mendix App

Rijkswaterstaat 14 Low-Code Applications at RWS RWS INFORMATION -

Open Items

•  Overall –  What are good thresholds for measurements? –  Incorporate metrics in acceptance criteria (Comply or explain) –  Appstore library management –  Can we get insight in Inter-App connections and Database

connections

•  Security –  Intra/Internet connections –  Scanning for security violations (backdoors, viruses, worms,

malware)
