Thoughts from the Past.Measurement, Incentives,
Agreements
  • "In physical science the first essential step in
    the direction of learning any subject is to find
    principles of numerical reckoning and practicable
    methods for measuring some quality connected with
    it. I often say that when you can measure what
    you are speaking about, and express it in
    numbers, you know something about it but when
    you cannot measure it, when you cannot express it
    in numbers, your knowledge is of a meagre and
    unsatisfactory kind it may be the beginning of
    knowledge, but you have scarcely in your thoughts
    advanced to the state of Science, whatever the
    matter may be.
  • Lord Kelvin ( Sir William Thomson ) PLA, vol.
    1, "Electrical Units of Measurement", 1883-05-03
  • It is not from the benevolence of the butcher,
    the brewer, or the baker that we expect our
    dinner, but from their regard to their own
    interest. Adam Smith
  • Man is an animal that makes bargains no other
    animal does this - no dog exchanges bones with
    another. Adam Smith

PBL Definition and Guidance
  • The Office of the Secretary of Defense (OSD) has
    defined PBL as a strategy for weapon system
    product support that employs the purchase of
    support as an integrated performance package
    designed to optimize system readiness. It meets
    performance goals for a weapon system through a
    support structure based on performance agreements
    with clear lines of authority and
    responsibility.
  • Army Guidance AR 70-1
  • The extent and level of detail to which PBL will
    be applied will be based on a business case
    analysis (BCA).
  • PBL will be implemented on all ACAT I and ACAT
    II programs, where PBL is proven to be
    economically and operationally feasible. PBL
    will be applied to ACAT III programs at the
    discretion of the PM, with approval from HQDA.
  • When a PBL strategy is used, the PM will
    designate a product support integrator (PSI) to
    integrate all product support for the system.
  • PBL must be tailored to individual system
    needs.
  • PBL will be executed through performance based
    agreements (PBAs) with, at a minimum, the using
    MACOM(s) and the product support integrator
    (PSI).
  • Army Guidance includes constraints with theme of
    need to integrate with standard Army systems and
    structures

PBL Metrics Importance
  • PBL Concept Links Outcomes, Agreements
    Incentives
  • PBL Metrics are an integrating performance
    thread.
  • Use of at least one of the overarching metrics
    is preferred. However if a sub-element is better
    suited for use in evaluating a PBL strategy for a
    particular system, use of that element is
    acceptable as well. The metric or sub-element
    selected should be able to measure success or
    failure of the Product Support Providers (PSPs)
    and/or the Product Support Integrator (PSI).
    When properly applied, the metrics will ensure
    successful evaluation of Army PBL efforts. From
    Draft HQDA PBL Metrics Policy Letter
  • PBL Business Case Analysis rests on performance
    proposition being worth cost. Performance
    proposition infers Metrics.
  • PSI must be able to manage PSP performance
    through Metrics
  • Metrics must be identified, defined and
    incentivized in PBL PBAs.
  • Otherwise---the result is either a performance
    strategy or a logistics strategy but not a
    Performance Based Logistics Strategy.

PBL Overarching Metrics
  • Logistics Response Time (LRT)
  • How responsive is Sustainment System
  • Logistics Footprint
  • What is my Logistics burden to deploy, move
    sustain?
  • Cost Per Unit Usage
  • What does it cost to operate, maintain
    sustain?
  • Operational Availability
  • What is my Materiel Readiness?
  • Mission Reliability
  • How Reliable will this be in use?
  • Many Sub Elements to these Metrics!!!
  • Note these are my characterizations see PBL

PBL Metrics Implementation
  • Implementation Concerns (From Draft Policy Guide)
  • Early Planning for Data Collection
  • Data Sources and Limitations
  • Burden on Field Units (Metrics Implementation
    burdens)
  • Automated Sources and Recording
  • Negative Analysis (what could go wrong in Metrics
    process)
  • Policy and Doctrine (Metrics Implementation vs
    Policy)
  • Review Boards (Data)
  • Early Determination of System Definition and
    Usage Factors
  • Accounting for Modeling and Configuration
    Differences
  • Sample Data versus Total Population
  • Funding Resources
  • Scope of Implementation Concerns vary by System
    and Metric !!!!

PBL Overarching MetricsChallenges
  • Operational Availability
  • Complex Metric
  • Many Different PSP players.
  • Operational/Mission Reliability
  • Dont confuse with Readiness
  • Data Collection in Field vs Test Environment
  • Logistics Footprint
  • Optimal vs Minimal
  • Whats behind a larger Footprint (e.g Mission vs
    Reliability)
  • Cost Per Unit Usage
  • Attributable Costs vs Common Items vs Overhead
  • Whats behind higher costs? (e.g who controls?)
  • Logistics Response Time
  • Which part of Logistics/Supply Chain?
  • Consider all actions for all situations measured

PBL Metrics Implementation Issues and Cautions
  • PBL must not become merely a matter of least cost
    against minimum readiness criteria.
  • It is important to be able to distinguish the
    nature of each metrics requirements for deployed
    versus those engaged in normal peacetime
    training.
  • When considering and overall Logistics Strategy
    Warfighter benefits in responsive and robust
    reliability design and support approach are not
    always quantifiable in metrics. Metrics are
    important but when the benefits are not always
    quantifiable, logisticians should be ready to use
    analytical judgment in determining strategy.
  • Dont confuse PSI and PSP in Metrics
    Implementation.
  • Dont underestimate the difficulty of Field Data
    Collection or potential incompatibility of STAMIS
    Data to PBA Metric usage.
  • Need PBAs with all Key contributors/participants
    in Metrics (Multiple PSPs for Single Metric?)
  • Dont promise more in your PBL Strategy and BCA
    than there is the practical ability to deliver in
    Implementation.

PBL Metrics Concluding Thoughts
  • Plan for Metrics Strategy Upfront Iteratively
  • Dont Underestimate Complexity of PBL Metrics
    Implementation
  • Understand the PBL Issues as relates to Metrics.
  • PBL is still very new for Tactical Army in real
    practice.
  • Be very careful of any product that promises
    trouble free Metrics measurement.
  • For a long time it puzzled me how something so
    expensive, so leading edge, could be so useless,
    and then it occurred to me that a computer is a
    stupid machine with the ability to do incredibly
    smart things, while computer programmers are
    smart people with the ability to do incredibly
    stupid things. They are, in short, a dangerously
    perfect match.

DOD PBL
  • Background
  • On September 30, 2001, the Quadrennial Defense
    Review (QDR) mandated implementation of
    Performance-Based Logistics (PBL) and modern
    business systems with appropriate metrics to
    compress the supply chain, eliminate
    non-value-added steps, and improve readiness for
    major weapons systems and commodities. PBL
    delineates outcome performance goals of weapon
    systems, ensures that responsibilities are
    assigned, provides incentives for attaining these
    goals and facilitates the overall life cycle
    management of system reliability, supportability,
    and total ownership costs.
  • The Office of the Secretary of Defense (OSD) has
    defined PBL as a strategy for weapon system
    product support that employs the purchase of
    support as an integrated performance package
    designed to optimize system readiness. It meets
    performance goals for a weapon system through a
    support structure based on performance agreements
    with clear lines of authority and
    responsibility.
  • DOD Acquisition Policy
  • The DoD Directive 5000.1 states The PM shall
    develop and implement performance-based logistics
    strategies that optimize total system
    availability while minimizing cost and logistics
    footprint. Sustainment strategies shall include
    the best use of public and private sector
    capabilities through government/industry
    partnering initiatives, in accordance with
    statutory requirements
  • DOD 5000.2 3.9.2.6 States Sustainment
    strategies shall evolve and be refined throughout
    the life cycle, particularly during development
    of subsequent increments of an evolutionary
    strategy, modifications, upgrades, and
    reprocurement. The PM shall ensure that a
    flexible, performance-oriented strategy to
    sustain systems is developed and executed.

Army PBL
  • Army Acquisition
  • PBL Extract From Page 4-5 AR 701 31 December
    2003 (Para 1.5 x)
  • x. Performance-based logistics. Performance-based
    logistics (PBL) is the preferred support strategy
    for materiel systems. The Army will implement PBL
    on weapon systems in order to provide the
    warfighter increased operational readiness
    increased reliability enhanced logistics
    response times enhanced deployment reduction in
    the logistics footprint and reduction in
    logistics costs.
  • Army Performance Based Logistics (PBL) Concept
    (AR 700-127 1.5 a)
  • Performance-based logistics (PBL) is the
    Department of Defense (DoD) preferred product
    support strategy for weapon system product
    support that employs the purchase of support as
    an integrated performance package designed to
    optimize system readiness. PBL is the delineation
    of output supportability requirements for
    acquisition systems and the assignment of
    responsibilities and incentives for the
    attainment of these requirements.

Army PBL Guidance (AR 70-1)
  • The extent and level of detail to which PBL will
    be applied will be based on a business case
    analysis (BCA).
  • PBL will be implemented on all ACAT I and ACAT
    II programs, where PBL is proven to be
    economically and operationally feasible. PBL
    will be applied to ACAT III programs at the
    discretion of the PM, with approval from HQDA.
  • When a PBL strategy is used, the PM will
    designate a product support integrator (PSI) to
    integrate all product support for the system.
  • PBL must be tailored to individual system
    needs.
  • PBL will be executed through performance based
    agreements (PBAs) with, at a minimum, the using
    MACOM(s) and the product support integrator
    (PSI).

20
PBL constraints
  • The following will serve as constraints in the
    design and implementation of a PBL strategy.
  • The approach must be transparent to the field
    user. Transparency will be determined by any
    changes in how the field user is trained to
    perform logistical activities.
  • Contractors on the battlefield policy will be
    followed unless a written waiver is obtained as
    defined in AR 7159.
  • The PSI will integrate with existing and future
    logistics systems, that is, STAMIS and WLMP.
  • Total asset visibility (TAV) will be maintained.
  • Standard Department of Defense (DOD)
    distribution hubs will be used for all
    contingency and wartime operations.
  • Note the theme of integrating into Army Logistics
    Systems/Structures

PBL Overarching Metrics
  • Logistics Response Time (LRT)
  • Definition Logistics Response Time is the
    period of calendar time from when a
    failure/malfunction is detected and validated by
    the maintainer to the time that the
    failure/malfunction has been resolved. This
    includes the time from when a need is identified
    until the provider satisfies that need, all
    associated supply chain and maintenance time, and
    delivery times of parts
  • Formula LRT (Date (or time) of satisfaction
    of the logistics demand) minus
  • ( Date (or time) of issue
    of logistics demand)
  • Logistics Footprint
  • Definition The government/contractor size of
    logistics support required to deploy, sustain,
    and move a weapon system for a given mission
    profile. Measurable elements should include but
    not be limited to inventory/equipment,
    personnel, facilities, transportation assets,
    supply, and real estate. Measures should
    quantify the footprint, i.e. weight, area,
    volume, and personnel etc. as appropriate.
  • Formula Logistics Footprint encompasses a wide
    variety of elements that having one specific
    formula will not envelop the entire embodiment of
    logistics support. However, each element can be
    quantified, measured, and assessed individually.
    These individual assessments can then be
    integrated as an overarching logistics footprint
    analysis.
  • Logistic Footprint is a function of various
    elements to include area (a), volume (v), weight
    (w), and support personnel (sp)

PBL Overarching Metrics (cont.-1)
  • Cost Per Unit Usage
  • Definition The total Operating and Support
    costs, to include overhead and management costs,
    for a weapon system usage attributable to a given
    unit of usage under established conditions.
    Usage can be measured in terms of unit density or
    individual weapons system usage factors include
    miles, rounds, launches, flight hours, time,
    systems, etc.
  • Formula Total Operating Support Costs
  • Miles/Rounds/Launches/Flight hours
  • Operational Availability (Ao)
  • Definition The percent of time that a weapon
    system or SoS is mission capable
  • Formula Over any period of time, the directly
    measured Ao (post-fielding) isAo Up Time /
    Total Time Up Time / (Up Time Down Time)
  • The expected long-term, steady-state Ao
    (throughout the life cycle) is determined from
    the classic formula
  • Ao MTBF/ (MTBF MTTR MLDT)
  • Note that Preventative Maintenance must not be
    ignored in overall Assmt. Also be careful about
    standby time.

24
PBL Overarching Metrics (cont.-2)
  • Mission Reliability
  • Definition The measure(s) or ability of a system
    to achieve Operational Performance (OP) for a
    defined mission or specified mission profile.
  • Formula ( Number of successful missions) Divided
    by
  • (Number of attempted missions)
  • Alternate Use of Formula  this may be used where
    MR success is best measured in terms where
    discrete mission success does not provide best
    meaning for this metric.  This is the formula
    where OP is measured as a percentage of
    Mission Duration (MD).  
  • Therefore  MR   (Total Operational Performance
    for MD) Divided By (Total Mission Duration)
  • Many Sub-elements possible for Each Overarching
    Metric
