Examples of results: a focus on economies of alignment generates significant savings

Domain Result

NATO AWACS Significant interoperability risks at alignment levels, both technical and organizational. Needed to evaluate cost impact, but crossing organizational boundaries (equipment costs vs operational costs).

NHS Orthotics Focus on Alignment Processes => 30% efficiency improvement and x10 payback over 10 years from improved patient mobility. But crossed organizational boundaries (impact on Social Services).

UAVs Interdiction of fleeting targets

Total savings of about 40% through focus on creating economies in the costs of alignment. Impact of UORs on cost of capability had doubled acquisition cost. Savings involved defining capability at different level.

e-Government Swine Flu Changed architecture of search capabilities combined with focus on creating economies of alignment across departments produced savings of ~80%, but crossed organizational boundaries.

BAE Systems Naval surface capability

More modular elements combined with focus on creating economies of alignment could produce savings of ~40%, but changed level at which purchaser-provider relationship had to be defined.

The demand for operational agility: agility depends on the variety of geometries-of-use supported

• The demand for operational agility creates a demand for flexibility in the way a Force Element can be used.

• The demands on a Force Element for flexibility is driven by the variety of different forms of collaboration* demanded of it.

Variety of Demands across Campaign Types: What is happening to the variety of demands?

• The larger proportion of operational time is spent in the top-right quadrant.

• The trend across the whole range of Campaign Types is towards encountering increasingly asymmetric threats, increasing the variety of demands.

• “It is clear that the challenges of the future will demand even greater institutional agility in the face of major resource constraints and some profoundly worrying indications that the West may be losing the initiative in terms of dictating the way war is fought” (MoD, Future Character of Conflict, in Strategic Trends Programme2010.)

Copyright © BRL 2013

Architecture for increasing agility: Increases reliance on systems-of-systems external to Force Elements

• Proposed changes in architecture introduce:

– Increased modularity of Force Elements

– Increased reliance on systems-of-systems external to Force Elements

• Value for Defence is ability to meet variety of Mission Situations across range of Campaign Types at reduced cost

– Value of changes depends on specific nature of variety

Operational agility, aligning composite operational capabilities to mission demands

Acquisition agility, generating operationally available capabilities across the DLoDs

Balancing acquisition and operational agility: Achieving a double agility demands a layered architecture

• Balancing these two forms of agility and their corresponding costs involves spanning a number of different layers of organization.

COHESION COSTING

17

Page 18: Value for defence

Copyright © BRL 2013

Cohesion Costing: Cohesion cost = Cost of using Force Elements + Cost of Alignment

• A different costing model is needed to identify the total operational costs of responding to particular types of mission situation – cohesion costing.

– Cohesion costing combines the costs of use of particular Force Elements with the costs of aligning their use in combination in relation to particular types of mission situation.

Analysis of Value for Defence: Reducing both the average and the variation in total operational costs

• The value of an architectural change is the impact of both the reduced average and the reduced variation*

• ‘Real Option’ pricing allows a value to be assigned to the change in spread/variance

a’b’

Value for Defence from: 2. Change in spread/variance

in levels of defence expenditure, based on the

difference between the two curves ‘a’ and ‘b’

Probability

Levels of total operational expenditure on Concurrent Campaigns

The total operational cost of approach ‘b’ across the variety of mission situations

b

a The total operational cost of approach ‘a’ across the variety of

mission situations

Value for Defence from: 1. Reduction in average level of

defence expenditure through impact of trade.

* Agility = property of the force package enabling it to do more things with the same underlying force elements.

Agility: The variety of capabilities that can be generated at threat tempo

• The operational agility of a Joint Capability Package is the variety of capabilities that it can generate at demand/threat tempo.

• The acquisition agility of a supplier is the variety of Force Elements that it can provide at acquisition tempo.

Demand for Force Elements at acquisition tempo

Alignment Processes orchestrating and synchronizing the use of Force Elements at alignment tempo

23

Page 24: Value for defence

Copyright © BRL 2013

Current Approach: Capability acquisition is largely stovepiped

• The MoD’s acquisition focus has been on the Force Elements capable of countering the most demanding threats, encountered primarily in inter-state conflicts.

– The acquisition and deployment of a Force Element includes its systems-of-systems that can be assumed to reside under a single operational1 and managerial2 authority.

– The costs of operational use are established through activity-based costing, focusing on the costs across the DLoDs that directly contribute to the operational use of the Force Element.

• The costs of aligning the use of multiple Force Elements to the demands of particular mission situations either remains implicit in the use of particular Force Elements, or belongs to another type of enabling Force Element providing the capability for Information Superiority (viz CCII and ISTAR).

1 Authority over the way the Force Element is used as a part of an operationally deployed Force Package. 2 Authority over the way the Force Element is made available for use by operational authority.

Early Systems Engineering: Agility is directly impacted by Software Architecture

• 2. External Interface Complexity – The interaction of multiple systems that were not designed together (e.g., military satellite

communications [MILSATCOM]), often termed “systems of systems,” also can greatly increase the difficulty of creating a stable requirements base for a new system.

• 3. System Complexity – The downside is that these new capabilities can tempt designers into unnecessarily complex concepts and

designs that impose a “cost of internal complexity” similar to the external complexity costs described above. In particular, there can be a tendency to assign poorly-thought-out functions and options to the software.

• 4. Incomplete or Unstable Requirements at Milestone B – As the missions and user communities have become more complex, the government is finding it much

more difficult to resolve competing views of system concepts and performance requirements.

• 6. Reliance on Large Amounts of New Software – Large, complex software elements have been the source of high costs and long development times on

many programs. The committee believes that most often this is not due to the difficulty of the software design, but rather reflects an inadequate definition of the software requirements prior to initiating the software development effort. Poorly-thought-out and ambiguous requirements seem to be an even greater addiction in software than in systems as a whole.
