## Fully Dressed
|
|
|
|
- **Scope:** NATO alphabet tool
|
|
- **Level:** user-goal
|
|
- **Primary Actor:** User, as named in [UCD-001]
|
|
- **Stakeholders and Interests:**
|
|
- S01 — a correct result for every letter, kept simple
|
|
- S02 — a readable behaviour that can be compared with their own solution
|
|
- **Preconditions:** the NATO alphabet data is available to the tool
|
|
- **Postconditions (success guarantee):** the User has seen the NATO code word of each letter of the word, in the order of the letters
|
|
|
|
### Main Success Scenario
|
|
|
|
1. The User starts the tool.
|
|
2. The tool asks for a word.
|
|
3. The User enters a word made of letters.
|
|
4. The tool shows the NATO code word of each letter, in order.
|
|
|
|
### Extensions (Alternative / Exception Flows)
|
|
|
|
- 3a. The word contains a character that is not a letter:
|
|
1. The tool tells the User that only letters are allowed.
|
|
2. The tool asks for a word again (back to step 2).
|
|
|
|
### Special Requirements / Business Rules
|
|
|
|
| Step | Rule |
|
|
| --- | --- |
|
|
| 3 | Upper-case and lower-case letters give the same result |
|
|
| 4 | Each letter A to Z maps to exactly one code word from the supplied alphabet |
|
|
|
|
### Open Issues
|
|
|
|
- None.
