Block 2 Algorithm Drop Schedule (aka NPP/J1 Algorithm Paradigm Shift)

IDPS Splinter

June 8, 2011


Overview

Overview

  • Issue: Planned “Build 2.1” algorithm drops in 2011 and 2012:

    • 2.1 drops are currently planned too early in the lifecycle when compared with reality

  • Background:

    • Raised issue at the IDPS Splinter on April 5, 2011

      • Government confirmed the dates are unrealistic, and that any major changes to algorithms will likely occur on the NPP Cal/Val path vs. reactions to J1 sensor deltas

    • Revisited issue at IDPS Splinter on May 10, 2011

      • IDPS proposed two options to handle “2.1” drop schedule: 1) Rebaseline hours into FY14-15; or 2) Repurpose the hours to support Cal/Val

      • Government indicated their support for option (2)


Status

Status

  • Option (2) briefed to Raytheon PMO over last several weeks

    • Direction was to incorporate option (2) algorithm paradigm changes into DRW12 planning cycle

    • Option (2) will take effect in Oct 2011 with approval of DRW12 BCR


Option 2 effects

Option 2 Effects

  • Algorithm drops

    • Drop sizes as listed in the JPSS proposal

    • Schedule as planned during DRW 11

    • Future Block 2 update budget reduced by 5,000 DSLOC from 11,750 to 6,750

Re-purpose FY11-12 drops to Cal/Val algorithm support in FY12-13


Option 2 effects1

Option 2 Effects

  • Re-purposing 5,000 DSLOC to Cal/Val Algorithm Support

    • 75% of the DSLOC (3,750 DSLOC) to Sustainment for Cal/Val algorithm changes from NASA

    • Remaining 25% (1,250 DSLOC) used by Development to keep development algorithm baseline in sync with Sustainment

  • Sustainment Cal/Val

    • Currently scoped to accommodate 9.5% change in PRO code

    • Additional DSLOC would increase code change capacity to ~11.8% of PRO code


Summary

Summary

  • Intend to repurpose FY11-12 C1 Algorithm hours for Cal/Val support in DRW12 planning

  • Provides additional algorithm code change capacity during Cal/Val

  • Budget for future Block 2 updates is reduced

Dev sustainment hrs

Dev – Sustainment Hrs

  • Proposed change retains total algorithm hours, but re-spreads them between Development and Sustainment

    • Slight shift between fiscal years


Npp cal val algorithm support

NPP Cal Val Algorithm Support

  • Proposed change adds surge staff for Sustainment algorithm updates during Cal/Val


Npp cal val algorithm support1

NPP Cal Val Algorithm Support

  • Proposed change retains staff for merging algorithm changes into development baseline
