# Secure assignments using a people list

> This page is intended for **administrators and managers** who prepare
>  assignments. For the field-side view, see
>  [The responder space](https://www.kafinea.com/en/documentation/project-management/the-responder-area-view-and-accept-my-assignments/).

## Objective

When you mobilize many responders, you want **each
 assignment to be visible only to the right people**: those in the right
 geographic area, with the right qualifications, or meeting any other criterion.
 That is the role of **people lists**.

The principle is simple: you link a **people list** to an
 assignment. Only people who meet the criteria of this list will see
 the assignment in their space and will be able to sign up for it. Each assignment can
 be linked to a different list.

## Step 1 – Describe your responders

Enter your responders in the **People** module, with the fields you will
 use to segment them: geographic area, skills, availability,
 status… The more precise your segmentation criteria are, the more relevant your lists will be.

## Step 2 – Create people lists

In the **People** module, create **lists** (filtered views) that match
 your needs, for example:

- a "Responders – North zone" list;
- a "Inventory-qualified responders" list;
- a "Available on weekends" list.

A list is defined by **criteria**: anyone who meets these
 criteria is automatically included in the list, with no manual management.

> To open an assignment to **everyone**, simply link it to a
>  list that contains all people.

## Step 3 – Link a list to an assignment

On the **project task** (the assignment), choose the **authorized people
 list** and indicate that the assignment **accepts sign-ups from
 the responder space**. Specify the desired number of **slots**.

From there:

- only people on the list can see the assignment;
- they can sign up as long as slots remain;
- other people see **nothing** about this assignment.

> **Important**: an assignment **without a list** is visible to no one. This is
>  intentional: as long as you have not designated who can see an assignment,
>  it remains closed.

## Real security, not just a display filter

The people list is not just a display filter: authorization is
 **rechecked at every sign-up and every cancellation**. A person therefore cannot
 bypass the rule to sign up for an assignment that is not open to them.

## Notify the relevant people

When an assignment is opened, Kafinea can **notify by email** the
 people on the authorized list so they sign up quickly, which is
 useful when you need to staff an assignment urgently.

## Handle the load

This mechanism is designed for **high volumes**: thousands of responders and
 assignments, with **sign-up spikes** when many people log in
 at the same time. Lists remain **smooth to browse** even at large
 scale, and slots are allocated **without overbooking**.
