# SLA Calculator

A web-based SLA (Service Level Agreement) calculator for the eCom Content Factory. Replaces the Excel-based workflow with a 4-step wizard that PMs use to estimate project timelines and determine if deadlines can be met.

There are **two versions**:
- **Full Calculator** (`index.html`) — For PMs: 4-step wizard with full stage-by-stage configuration, Gantt chart, CSV/iCal export
- **Client Estimator** (`client.html`) — For clients: single-page form with 4 inputs, uses SLA defaults automatically

## How It Works

1. **Select Brief Type** - Choose from 9 brief types (Country Pull, Global Push, Local Push, Urgent, etc.). Each brief type displays a scope description and auto-populates which of the 8 project stages apply.
2. **Configure Stages** - Toggle stages on/off, set complexity levels, asset volumes (up to 300-400), revision rounds (supports decimals), and market approval days.
3. **Enter Dates** - Set the project kick-off date and required go-live date.
4. **View Results** - See the full timeline breakdown (List + Gantt views), key dates per stage, and a clear Y/N verdict on whether the deadline can be met.

## Project Structure

```
index.html        - Full PM calculator (4-step wizard, Gantt chart, CSV/iCal export)
script.js         - Full calculator engine + form dynamics
client.html       - Simplified client-facing estimator (single page)
client-script.js  - Client estimator engine (uses config defaults)
config.json       - All business rules (shared by both versions)
```

## Editing Business Rules

All assumptions, stage definitions, complexity levels, cross-reference tables, tooltips, and default values live in `config.json`. Non-developers can edit this file to update:

- **Brief types and stage matrix** - Which stages apply to which brief type
- **Production cross-reference table** - Days by complexity x asset volume
- **Syndication cross-reference table** - Days by complexity x EAN volume
- **Translation word count ranges** - Days by word count bucket
- **Opera Upload days** - Days by asset volume
- **Default values** - Revision rounds, market approval days, revision days per round
- **Tooltips and descriptions** - Help text shown to PMs in the UI
- **Syndication buffer** - Currently 10 business days (configurable)

## Key Calculation Logic

- Uses **business days** (Monday-Friday), not calendar days
- Each active stage adds: Handover (1 day) + WIP days + Market Approval days + (Revision Days x Rounds)
- **Syndication buffer**: When syndication is active, a 10 business-day buffer is added to the suggested go-live date
- **Stages 4 & 5** (Translation PDP + Asset) run in parallel and share one set of inputs
- **Opera Upload** is mandatory for all brief types — the toggle is locked on and cannot be deactivated by users (controlled via `alwaysActive: true` in config.json)

## Features

- Dark mode toggle (persists to localStorage)
- Mobile responsive layout
- Export to PDF (landscape A4)
- Export to iCal (.ics) with key milestone dates for Outlook/Google Calendar
- Real-time calculation on every input change
- Tooltips matching the original Excel comments
- Non-contractual dates disclaimer banner
- Brief type scope descriptions displayed as bullet lists
- Gantt chart view alongside list view in results

## Running Locally

Open `index.html` in a browser, or serve with any static file server:

```bash
npx serve -l 8080
```

Then visit `http://localhost:8080`.

## Verified Against Excel

The calculator has been verified against the original Excel workbook example:

| Input | Value |
|---|---|
| Brief Type | Country Pull - Simple |
| Active Stages | Production + Opera Upload |
| Production | Simple / 50-100 Assets / 0 revisions / 50% speedup |
| Kick-off | 6 Mar 2026 |
| Go-Live | 9 Mar 2026 |

| Output | Value |
|---|---|
| Production Complete | 16 Mar |
| Opera Upload Complete | 19 Mar |
| Verdict | N (cannot meet deadline) |

## Changelog
