Stages alpha, bêta et en direct :

• travaillez de façon agile, à l’aide d’outils et de techniques agiles, et continuez de la sorte une fois que le service est opérationnele (Normes des services numériques (Ontario / UK / AU))
• assurez-vous que l’équipe examine et met à jour de façon incrémentielle les façons de résoudre les problèmes (Normes des services numériques (Ontario / UK / AU))
• montrez que votre service est géré de façon agile, en s’appuyant sur des objectifs clairs et mesurables (Normes des services numériques (Ontario / UK / AU))
• examinez les options de conception pour votre prototype et expliquez pourquoi certaines sont écartées (Normes des services numériques (Ontario / UK))
• Start with a prototype (3. Apply agile principles and be iterative. (Do - Digital Design Playbook (ISED)))
  • Create a minimum viable product, that is, a version of the service with just enough features to gather insights, test assumptions and inform future improvements. Use the prototype to capture client feedback and then make improvements until you have a version that really meets client needs.
• When iterating, focus on workable solutions over comprehensive documentation. (3. Apply agile principles and be iterative. (Do - Digital Design Playbook (ISED)))
  • Having a workable solution that can be tested and validated will give you useful information for improving your service. Whenever possible, focus on results rather than unnecessary documentation and reporting (while staying within policy and regulatory limits).
• When you can, use agile tools and techniques. (3. Apply agile principles and be iterative. (Do - Digital Design Playbook (ISED)))
  • Techniques can include: daily stand ups, issue trackers, code reviews, rapid prototyping, design sprints, usability testing, user stories, retrospective meetings.
• make sure you have the ability to deploy software frequently with minimal disruption to users (Digital Service Standard (UK))

Live stage:

• make sure deployments have zero downtime in a way that doesn't stop users using the service (Digital Service Standard (UK))
• make sure you have enough staff to keep improving the service (Digital Service Standard (UK))

• Start small and build upon successes. (General design principles - Digital Design Playbook (ISED))
• Don’t wait for a fully developed service to start testing. (1. Test the service before launching the service. (Assess - Digital Design Playbook (ISED)))
  • Develop a prototype of the service and test it to validate ideas, to challenge assumptions and to identify opportunities for improvement.

[TODO: Ajouter / modifier les éléments de la liste de contrôle]

• dotez-vous d’un plan de vérification de la qualité et de correction qui soutient des modifications fréquentes du service (Normes des services numériques (Ontario))
• utilisez une approche par étapes pour tester les modifications apportées à une partie du service, lorsque des modifications basées sur les caractéristiques ne sont pas réalisables (Normes des services numériques (Ontario))
• Define your testing objective (1. Test the service before launching the service. (Assess - Digital Design Playbook (ISED)))
  • Define the purpose of the test and what you want to learn? The purpose of the test is often determined by your business goals and user needs identified through feedback, analytics and other sources.
  • Identify top or critical tasks to test. Main outcomes and features your clients want to achieve should be prioritized.
• Test under realistic conditions (1. Test the service before launching the service. (Assess - Digital Design Playbook (ISED)))
  • Create realistic scenarios that reflect the context and environment in which clients would use the service.
• testez le service dans un environnement aussi semblable que possible à l'environnement de déploiement (Normes des services numériques (Ontario))
• Commit to regular service reviews (2. Product management, not just project management. (Assess - Digital Design Playbook (ISED)))
• Identify opportunities to improve the service based on the results of regular test (2. Product management, not just project management. (Assess - Digital Design Playbook (ISED)))
• analyze user research and use it to improve your service (Digital Service Standard (UK))
• Use different types of tests to assess the service (1. Test the service before launching the service. (Assess - Digital Design Playbook (ISED)))
  • Identify the best testing method based on your needs. Examples of tests include:
    • Tree Testing - A test in which participants are asked to find a resource based on a series of menus.
    • Card Sorting Testing - A reverse tree test where participants sort through items and group them together in a hierarchical manner.
    • First Click Testing - A test that observes the first item that a participant clicks on and uses the selection as an indication as to whether users are directed as intended.
• adoptez un processus de test des modifications apportées au service (Normes des services numériques (Ontario))
• mettez en place un processus périodique de contrôle et de test du service, même quand il n'a pas subi de modifications (Normes des services numériques (Ontario))
• Create automated tests that verify all user-facing functionality (Digital Services Playbook (US))
• Create unit and integration tests to verify modules and components (Digital Services Playbook (US))
• Run tests automatically as part of the build process (Digital Services Playbook (US))
• Conduct load and performance tests at regular intervals, including before public launch (Digital Services Playbook (US))
• Monitor system-level resource utilization in real time (Digital Services Playbook (US))
• Monitor system performance in real-time (e.g. response time, latency, throughput, and error rates) (Digital Services Playbook (US))
• Ensure monitoring can measure median, 95th percentile, and 98th percentile performance (Digital Services Playbook (US))
• Create automated alerts based on this monitoring (Digital Services Playbook (US))
• Track concurrent users in real-time, and monitor user behaviors in the aggregate to determine how well the service meets user needs (Digital Services Playbook (US))
• Use an experimentation tool that supports multivariate testing in production (Digital Services Playbook (US))
