04Chapter scope

What this chapter gathers.

The chapter covers humanitarian risk analysis and displacement: who is displaced by disasters and conflict, for how long, and what protection and assistance standards apply.

05Process

How the process runs.

Process explorer · Process

Humanitarian risk and displacement: Working group, charter to sunset

9 steps4 stages1 gate

Process

Humanitarian risk and displacement: Working group, charter to sunset

A working group is chartered by record for a fixed timebox, delivers bounded assignments, drafts and recommends, then dissolves unless renewed; it does not adopt.

  1. 01 Form

    1. 01NLC proposes the groupDecision · National Leadership CouncilThe NLC proposes working groups and nominates chairs, editors and experts from its leadership pools. It does not charter.
    2. 02Charter by recordDecision · National Standards CouncilA working group is chartered by record for a timebox of at most twenty-four months. The charter sets its scope, roles and decision rule.
    3. 03Members join by competenceStep · MembersExperts, practitioners, students and volunteers join by competence. Members declare interests and recuse on conflict.
  2. 02 Work

    1. 04Workplan from the national agendaStepAssignments come from the national agenda and the year’s missions. Each states the competence it needs and how the work will be reviewed.
    2. 05Drafts and deliverables, delivered monthlyRecordGroups deliver monthly. For standards they draft the national profile and deviation register and run national public comment and pilots.
  3. 03 Review

    1. 06Contribution record and reviewGateEach contribution is recorded and reviewed. A working group drafts and recommends; it does not adopt.
    2. 07Recognition follows the recordRecordContribution records are kept, so that recognition follows the record.
    3. 08National adoption is decided elsewhereDecision · National Standards CouncilThe National Standards Council decides the adoption mode and the national profile. The working group proposes and never decides.
  4. 04 Close

    1. 09Dissolved by default, or renewed by recordDecision · National Standards CouncilA group is dissolved by default at the end of the timebox. The National Standards Council renews or closes it, on the NLC’s proposal.

National Working Groups · National Standards Council · Decision rightsDesigned programme process, not a record of operation. No cycle has run and every programme is at service level R0. A gate is a programme decision, never a public-authority approval, certification or deployment authorisation. No working group is constituted. The charter rules belong to the proposed Nexus Standards working model.
