## What is Optimal Workshop?

Optimal Workshop is a research platform specializing in information architecture (IA). It provides three main tools: card sorting, tree testing, and first-click testing. All three measure how users organize, navigate, and find information.

Card sorting asks: "How would you organize these items?" Tree testing asks: "Can you find this item in this structure?" First-click testing asks: "Where would you click to find this item?" Each reveals different aspects of IA.

**One sentence punch:** Optimal Workshop validates your information architecture before you design—saving months of wasted design on wrong structures.**

## Why Designers Use Optimal Workshop

- **Quantitative IA Data** — Instead of debating whether "Settings" should go under "Account" or "Preferences," test it. Data answers.
- **Remote Testing** — Recruit globally. Send a link. Get results back. No moderation required.
- **Affordable at Scale** — Running a card sort with 100 participants costs less than in-person research. Larger sample size = stronger insights.
- **Quick Iteration** — Run a card sort, get results in days. Update your IA. Run another test. Iterate fast.

## Optimal Workshop Tools

1. **Card Sorting** — Show 50 terms (features, pages, menu items). Ask participants to group them. See how users naturally organize.
2. **Tree Testing** — Show your IA structure. Ask "Can you find X?" Track where users click and whether they succeed.
3. **First-Click Testing** — Show a scenario and a screen. Where would you click to accomplish this task? Tracks first click accuracy.
4. **Surveys** — Standalone surveys for general questions (not IA specific).

## How to Use Optimal Workshop

### Card Sorting Workflow

1. **Compile list of items** — What are you organizing? Website navigation? Feature labels? Compile 30-60 items.
2. **Decide sort type** — Open sort (users create their own categories) or closed sort (users organize into your predefined categories).
3. **Create study** — Upload items. Set instructions. Choose participant count.
4. **Recruit participants** — Optimal Workshop handles recruitment or import your own.
5. **Analyze results** — Similarity matrices show which items users grouped together. Dendrograms visualize clustering patterns.
6. **Iterate** — If sorting is chaotic, refine items. Run another sort.

### Tree Testing Workflow

1. **Build a tree** — Create your proposed IA structure as a text tree.
2. **Create tasks** — "Find the return policy." "Where would you change your password?" Create 8-12 realistic tasks.
3. **Run test** — Recruit participants. They attempt tasks.
4. **Analyze** — Success rate shows if users find items. Click patterns show where users get lost.

## Interpretation Tips

- **Task Success Rate** — Below 80% suggests IA problems. Retest after changes.
- **Clicks to Success** — Fewer clicks = better navigation. If users take 5 clicks to find something 3 clicks deep, IA is confusing.
- **Abandon Rate** — Users who give up. High abandonment means IA is broken.
- **Direct Rate** — Percentage going directly to correct answer. 90%+ is excellent. 50%+ is acceptable.

## Mentor Tips

- **First tip: Test before you design.** Card sort and tree test on your proposed IA before designing the interface. Saves redesign cycles.
- **Include stakeholders in interpretation.** After running a test, don't interpret alone. Show raw data to stakeholders. Let them see user behavior.
- **Test edge cases.** Include items that seem obvious to you but might be ambiguous to users. Test assumptions.
- **Retest after changes.** One test is a baseline. If you redesign IA based on results, retest. Ensure changes improved findability.
