3 Low-Code Applications at RWSRWS INFORMATION -
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

4. Rijkswaterstaat
4 Low-Code Applications at RWSRWS 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)

5. Rijkswaterstaat
5 Low-Code Applications at RWSRWS 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

6. Rijkswaterstaat
6 Low-Code Applications at RWSRWS 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)

7. Rijkswaterstaat
7 Low-Code Applications at RWSRWS INFORMATION -
AQM Mendix applications
• Code quality rating (maintainability)

8. Rijkswaterstaat
8 Low-Code Applications at RWSRWS 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

9. Rijkswaterstaat
9 Low-Code Applications at RWSRWS 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.

10. Rijkswaterstaat
10 Low-Code Applications at RWSRWS INFORMATION -
AQM/SIG Monitor -I
• Duplication

11. Rijkswaterstaat
11 Low-Code Applications at RWSRWS INFORMATION -
AQM/SIG Monitor -II
• Architecture / Dependency graph

12. Rijkswaterstaat
12 Low-Code Applications at RWSRWS INFORMATION -
AQM/SIG Monitor -III
• Technology distribution

13. Rijkswaterstaat
13 Low-Code Applications at RWSRWS 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

14. Rijkswaterstaat
14 Low-Code Applications at RWSRWS 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)
