It is virtually impossible to understand everything about an SoS, let alone to influence all decisions made on behalf of its constituent components. It also identifies known risk areas and describes associated risk mitigation plans. AcqNotes is not an official Department of Defense (DoD), Air Force, Navy, or Army website. Hence, requirements for software assurance and other quality attributes related to software dependability and supportability need a strong emphasis. Incremental and Evolutionary Growth of System Definition and Stakeholder Commitment. The challenge is that while these drivers can affect current acquisitions, recommended practices for dealing with them do not yet exist. Typically, risk management has focused on only a single system, and often only on development risks. [Howard 2007]Howard, Michael. Copyright © Carnegie Mellon University 2005-2012. The evolution from stand-alone systems to systems with a few known interfaces to systems of systems increases the number and diversity of stakeholders. Stakeholder Satisficing: Identify and engage key stakeholders (i.e., those critical to success) early and often to validate and re-validate requirements, solutions, and plans and to discuss potential and proposed changes. At the same time, business and mission needs for SoS constituents continue to evolve, and users expect an ability to adapt their systems accordingly. Failures are frequently the result of multiple, often individually manageable errors that collectively become overwhelming. Pittsburgh, PA: Software Engineering Institute, Carnegie Mellon University, 2007. Consequently, the overall success of a business process depends on how these discrepancies are dealt with by staff and supporting computing systems. People stresses can consist of information overload that slows analysis, distraction (too much browsing) and a “Not my job” attitude, which can inhibit effective responses to problems.

There are no existing best practices to address these risk management problems. Table 4. The underlying assumptions were that requirements were static and that acquisition should concentrate on monitoring costs and schedule. For software, this has led to a growing gap between expectations and practice—in particular, the scope and complexity of socio-technical domains that are the context for many SoS creates challenges in the identification of requirements [Easterbrook 2007]. (a)) MDA. [Ward 2006]Ward, Mary Catherine, Elm, Joseph P., and Kushner, Susan. These milestones look at concurrent activities, which may span independently developed systems, with a view toward synchronizing, stabilizing, and assessing risk before obtaining commitment to proceed to the next development phase. A complementary step would be to generate a list of problems that might arise for such an acquisition and consider how these should drive strategy. Example options include “single step” (e.g., waterfall), incremental (phased development and deployment of defined capability), and spiral (evolutionary definition, development, and deployment). While the ICM does not explicitly focus on all relevant dependability and supportability quality attributes, ICM life cycle activities and anchor points can easily accommodate them. This heightened need to focus on adaptability and assurance, to emphasize a robust architectural foundation, and to expand the scope of risk management beyond the system boundary will heavily influence the acquisition strategy. .01Â Â Â Â Â The MRB Chair, the Department Deputy Secretary (see Figure 2), with advice from the Board’s members shall have milestone decision authority for high-profile programs and projects.Â The MRB Chair shall issue a Milestone Decision Memorandum at the conclusion of each milestone review (nominally within 15 calendar days) defining the program’s or project’s way ahead in the next phase including necessary procurement authorities, specific phase exit criteria, and other directed actions.Â The Chair may also direct that specific reviews and studies be undertaken to support a milestone review and may invite additional MRB participants as deemed appropriate to the program or project under review.Â The Deputy Secretary may delegate in writing, with rationale, MDA and management of any high-profile program or project to the Head of an Operating Unit.Â This does not exempt that program or project from adherence to the Acquisition Framework (and its minimum documentation) in this policy unless explicitly indicated in the delegation instrument. This must change, but it will change only when the acquirer incentivizes performance with respect to assurance and quality requirements, not just cost, schedule, and functionality. It describes major life cycle phases, activities, reviews, milestone and interim decision points, deliverables, and other such information. Considerable analysis and collaboration are required to develop a sound acquisition strategy. As another example, when components are reused or services shared as with service-oriented architectures, different component or service users may have conflicting requirements. In this example, an evolutionary acquisition life cycle model would likely be chosen to accommodate change and to emphasize the need for risk reduction activities related to unstable requirements. Acquisition planning must acknowledge a variety of risks and their impact on acquisition strategy elements. In such an environment, it becomes critical to specify requirements related to assurance goals and to build in the qualities needed to enable correct operation in the midst of a high degree of complexity and change.
