# Mobilizing thousands of field workers at scale

> 📍 **How to access this feature?**
> *Project management > Project tasks + People (lists) + Worker portal*

## The situation

Certain activities rely on a **pool of numerous temporary workers**
 mobilized for short missions, spread across many locations. It is necessary to
 **staff quickly**, ensure that each person only sees the missions that
 concern them, and **track attendance** in the field.

The most telling example is that of an **inventory company**: it mobilizes
 **thousands of inventory takers** across **hundreds of points of sale**, on
 short time slots, sometimes several hundred missions in the same month. When a
 manager announces that an operation is confirmed, **hundreds of people
 log in almost simultaneously** to reserve their spot.

> The same pattern is found in many other professions: see the
>  correspondence table at the bottom of the page.

## The objective

- Each worker sees **only** the missions that concern them.
- They **register independently**, from their phone, in a few seconds.
- They **verify their presence** on-site via an Identification Code.
- The organization **scales up** without losing responsiveness.

## Step-by-step configuration

### 1. Model the workers

Describe your pool in the **People** module, with the fields that will be used to
 **segment** them: geographic area, skills, qualifications, availability.

### 2. Create lists and partition visibility

Create **people lists** by criteria (area, qualification…) and
 **link them to missions** so that each mission is only visible to the
 right people. This is the heart of the system, described in detail in
 [Securing interventions by people list](https://www.kafinea.com/en/documentation/project-management/secure-assignments-using-a-people-list/).

### 3. Open the worker portal

Provide access to the **worker portal**: your workers can consult
 open missions, register, cancel if necessary, and view their history. See
 [The worker portal](https://www.kafinea.com/en/documentation/project-management/the-responder-area-view-and-accept-my-assignments/).

### 4. Manage the field: attendance and working time

On-site, the worker presents their **Identification Code** to confirm their
 **attendance**. When missions involve salaried employees, Kafinea
 also provides complete management of **timesheets** (entry and tracking of
 working time); see
 [Timesheets](https://www.kafinea.com/en/documentation/human-resources/timesheets/).

> Consider the **time zone** of remote sites (for example, overseas):
>  dates and day boundaries are taken into account according to the
>  worker's time zone.

### 5. Manage in real-time via the API

For organizations managing an operations **control tower**,
 Kafinea exposes an **API**. You can thus track the progress of registrations, attendance, and missions in **real-time**
 on your own
 dashboards or third-party tools. See
 [the Kafinea API](https://www.kafinea.com/en/documentation/api/rest-api-introduction/).

## Why Kafinea holds the scale

- **Controlled visibility**: each intervention is only open to the right
   people, and this rule is **actually enforced** (not just a simple
   display filter).
- **Long lists that remain fluid**: even with thousands of workers and
   interventions, the screens remain responsive.
- **Connection peaks absorbed**: during a registration rush, spots are
   allocated **without overbooking**.

## This model works in many professions

Inventory is just one example. The same system — pool of people, lists
 that partition visibility, independent registration, field attendance —
 applies to many activities:

| Profession | Workers | What is configured |
| --- | --- | --- |
| In-store inventory | Inventory takers | Lists by area and qualification; on-site attendance |
| Events | Hosts / hostesses | Lists by event and skill; entrance attendance |
| Sales promotion / merchandising | Promoters, brand ambassadors | Lists by brand and sector; point-of-sale attendance |
| Security / guarding | Agents | Lists by site and certification; attendance by shift |
| Cleaning | Cleaning agents | Lists by sector; attendance by site |
| Seasonal handling | Handlers | Lists by warehouse and availability; attendance by time slot |

In all cases, the framework remains the same: **describe the people**, **create
 lists**, **open missions**, **let workers register**, then
 **track attendance in the field**.
