Decision Points

The early stages of a project Lifecycle contain two major decision points as defined in the Approvals and Scrutiny process – Initial Gate and Main Gate.

Sponsors and project teams are required to develop a Business Case at both of these stages justifying the project proceeding to the next stage. No manufacture or service contract can be signed prior to approval.

Initial Gate: the Early Decision Point

Initial Gate remains the first approval point in the lifecycle. It occurs before any assessment work is undertaken and is considered to be a relatively ‘low hurdle’.

Projects will return to the appropriate Approval Authority if agreed targets are breached.

Main Gate: the Key Decision Point

Main Gate occurs after the assessment work has been undertaken and is the major decision point at which the solution and ‘not to exceed figures’ are approved.

Main Gate approval:

  • Remains the key investment decision point for Projects, where the risks to successful delivery are considered against the benefit of the proposed solution in meeting an endorsed Defence requirement. Risks can cover many aspects (for example, financial, technical, industrial, Defence Lines of Development (DLoDs)).
  • Sets targets against which the acquisition performance of the project is assessed. Targets are only established at Main Gate, when all the risks are sufficiently understood.
  • Establishes defined trade boundaries for the project.
  • Considers Whole Life Costs across all DLoDs. Crucially, it addresses the support solution as well as the equipment procurement.
  • Requires assurance by the User (generally the Front Line Command) that the proposal can be integrated across DLoDs and with existing systems. This is needed to deliver an effective military capability from In Service Date.

The Approving Authorities will expect to see at the Decision Points that a wide range of Acquisition lifecycle Strategies has been considered.
