Guidelines for Advanced LIGO Detector Improvement (DI) Project Review(s)

Document #:

LIGO-M1500263-v7

Document type:

M - Management or Policy

Abstract:

This document provides programmatic guidelines for the development phases of proposed Detector Improvements (DI) to the advanced LIGO (aLIGO) detector from the requirements and conceptual design phase through fabrication.
This document supersedes the Advanced LIGO document, M050220, Guidelines for Advanced LIGO Detector Construction Activities.

Detector Improvement (DI) Project Review Guidelines
* Large projects -- Multiple reviews
* Medium projects -- Single expedited technical review
* For small, straight-forward projects -- an ECR approval is sufficient

Associated notes for setting up review docs:
* L doc for Charge
* M doc for Review doc / Committee Report
* Source of example templates (with content)

Notes and Changes:

release (-v2) notes:
1) Switched the terminology from 'detector upgrade' to 'Detector Improvement (DI)' to be consistent with the activity based WBS for Operations starting in FY 2019, per M1700019
2) Notes that Systems Engineering defines expedited or abbreviated reviews for small scale/scope DI projects.

release (-v3) notes:
1.) added 'including cabling, feedthrough, stray light and viewport considerations.' to the PDR and FDR checklists.

release (-v4) notes:
1) added IRR checklist to section 11.4 and expanded IRR section 9.2.

release (-v5) notes:
1) Added key to IRR Checklist (section 11.4) to allow definition of what was intended as deliverables on Interfaces.
2) Added to IRR Checklist key (section 11.4) to allow definition of what was intended as deliverables on Software.

release (-v6) notes:
1) updated table 11.4 for IRR to expand on electronics and software deliverables.
2) confirmed risk registry review is included and referenced in the summary tables.

release (-v7) notes:
1) Included new requirement to include and review TRL at both PDR and FDR. (For now highlighted in yellow.)

release (-v8) notes:
Pending.
