Inconsistent Form Validation Timing in a Single App

说明与用途

应用中的三种表单使用不同的验证时机（输入时、失去焦点时、提交时），导致用户体验不一致。通过统一规则按字段类型和验证需求确定时机，提升了体验一致性。

问题

Three forms in one application exhibited different validation timing (on change, on blur, on submit), causing a fragmented user experience and inconsistent product feel.

结果

Consistent validation timing across forms reduced user confusion, improved perceived product quality, and bounded inconsistency growth for future forms.

工作流

• 1. Identify validation timing patterns in existing forms.
• 2. Draft a rule specifying timing per field type and validation need.
• 3. Communicate rule to the team and document it in design guidelines.
• 4. Refactor existing forms to align with the rule (change blur/submit logic).
• 5. Add submit‑time re‑validation and focus‑to‑first‑error handling.
• 6. Test new forms to confirm consistent behavior across the app.

证据

New forms consistently used blur validation for standard fields, which was the pattern that had previously appeared least often despite being the most appropriate for the majority of cases.
