Goal: By the end of Day 5, you'll have a clear ship it or not now recommendation, plus a short internal summary your lead and procurement can approve.

Before you start (30 minutes)

Spend 30 minutes setting up the evaluation so the trial doesn't drift. The goal is to make the next 5 days measurable and decision-ready.

• Pick one component to evaluate (for example, DataGrid for WPF) and define the primary use case (for example, data-heavy desktop screen with filtering, grouping, export, and editing).
• Choose a success owner (one dev) and a decision owner (tech lead/architect).
• Create a simple scorecard (1-5) for the criteria below.

Day 1 Define success + install + first proof

Outcome: You can run a minimal proof in your environment and you know exactly what success means.

Checklist:

• Confirm your top 3 must-have requirements and top 3 nice-to-haves.
• Identify your deal-breakers (for example: no virtualization, no export, theming limitations, licensing constraints).
• Install the trial and verify you can build/run in your target environment (CI if applicable).
• Create a small evaluation harness:
  • One screen/page that mirrors your real layout
  • Your real data model (or a representative subset)
  • Your real navigation pattern (dialogs, tabs, master-detail whatever you actually ship)
• Document first impressions:
  • Time-to-first-working-screen
  • Any friction points (setup, docs, licensing steps)

Deliverable: A one-paragraph Evaluation scope note for your team.

Day 2 Feature fit (must-haves only)

Outcome: You've proven the component can meet your core requirements without workarounds.

Checklist:

• Validate the must-have feature list using your real workflow:
  • Sorting and filtering behavior
  • Grouping and summaries (if relevant)
  • Editing and validation (if relevant)
  • Export expectations (formats and fidelity)
  • Column behaviors users expect (resize, reorder, hide/show)
• Confirm edge cases:
  • Empty states
  • Large values/long strings
  • Localization considerations (dates, decimals)
  • Error states and recoverability

Deliverable: Updated scorecard with notes for each must-have.

Day 3 Performance and real data stress test

Outcome: You know whether it stays fast under your actual load.

Checklist:

• Test with representative dataset sizes (what you ship today and what you expect in 12-24 months).
• Validate responsiveness:
  • Initial load time
  • Scroll/interaction smoothness
  • Filtering/grouping responsiveness
  • Memory behavior during heavy use
• Watch for UX regressions:
  • UI freezing during operations
  • Input lag while editing
  • Delays when switching views

Deliverable: A short Performance verdict paragraph: what's solid, what needs attention.

Day 4 The hard stuff: theming, UX consistency, accessibility

Outcome: You've validated whether the component will look and behave like your product.

Checklist:

• Theming and styling:
  • Match your app's typography, spacing, and colors
  • Validate dark/light modes if you support them
  • Confirm you can standardize styles across screens
• Accessibility and keyboard navigation:
  • Tab order and focus states
  • Keyboard-only usability for core flows
  • Screen-reader considerations (as applicable)
• UX polish checks:
  • Empty/loading states
  • Error messaging patterns
  • Consistent interaction patterns with the rest of your app

Deliverable: Screenshot set (internal) showing before/after styling alignment and any gaps.

Day 5 Integration reality + decision memo

Outcome: You can confidently recommend adoption (or not) with a clear rationale.

Checklist:

• Integration effort:
  • How well it fits your architecture (MVVM patterns, binding expectations)
  • How maintainable the implementation feels
  • Any constraints you discovered that would impact future features
• Support and documentation:
  • Note what was easy vs unclear
  • If you contacted support, record response time and usefulness
• Licensing and rollout:
  • Confirm licensing model aligns with your team structure
  • Identify what you'd need for production rollout (build pipeline, versioning, upgrade plan)

Recommendation: Adopt / Do not adopt / Re-evaluate later

Common mistakes (avoid these)

• Evaluating with toy data instead of real datasets.
• Testing every feature instead of your must-haves.
• Skipping theming/accessibility until later.
• Not writing down friction points while they're fresh.
• Letting the trial run without a time-boxed plan.
