A key part of Enabling Businesses and Enterprises to Perform Systems Engineering is deciding on the desired systems engineering capabilities within the business and/or enterprise. First, the Organizational Purpose must be understood, then the value that systems engineering can provide is determined. So understanding the value that Systems Engineering can provide within the organization in support of Organizational Purpose is the starting point for deciding the desired SE capabilities. This topic summarizes the issues that drive the decisions about desired Systems Engineering capabilities for the business or enterprise. This has to take into account the factors that cause organizations to be different, so the topic also discusses the organizational design decisions and issues that may arise; and also how SE may interact with other functional areas in the organization, and what needs to be done to ensure that Systems Engineering delivers maximum value to the organization.

Once the systems engineering capabilities of the business and enterprise are determined, these capabilities are divided among organizations, teams and individuals. Determination of team SE capability is discussed in the topic Determining Needed Systems Engineering Capabilities in Teams, and the individual SE competencies are discussed in the topic Roles and Competencies.

The capability to perform systems engineering includes factors such as having competent personnel, adequate time, sufficient resources and equipment, and appropriate policies and procedures. The SE capability of a business or enterprise is dependent on all these factors. Social dynamics at the team and organizational levels also influence the SE capability realized.

Relationship of this topic to Enterprise Systems Engineering

Enterprise Systems Engineering techniques can be used to establish needed SE capabilities. Architecture modeling and analysis enables better understanding of the dependencies between capabilities of nodes in the enterprise. At a high level of abstraction, the folowing are basic steps to decide on the desired SE capabilities within the business and enterprise.

  1. Understand the context, including the factors shown in Table 1
  2. Determine the required SE roles
  3. Determine the competencies and capabilities needed for each of the SE roles
  4. Assess the ability and availability of the needed SE organizations, teams, and individuals
  5. Make adjustments to the required SE roles based on the actual ability and availability
  6. Organize the SE function in a manner that facilitates communication, coordination, and performance.

See the topic Organizing Business and Enterprises to Perform Systems Engineering for additional information. More information on context and required SE roles is provided below.

Contextual Drivers

The table below provides a comprehensive list of contextual factors and drivers to be considered when deciding on the desired SE capability for a business and enterprise.

Required SE Roles

Enterprise Systems Engineering techniques can be used to establish needed SE capabilities from first principles. This implies the need for an enterprise systems engineering team, either permanent or ad hoc, that has both the necessary enterprise SE skills, and the necessary influence with senior decision makers in the organization.

After understanding the context for the business and/or enterprise, the next step is to determine the required SE capabilities. The SEI Capability Maturity Models for Acquisition, Development and Services (SEI 2010) provide a framework for selecting systems engineering capabilities relevant to different types of business and enterprise.

The SE roles and competencies the organization needs to develop depend on the capabilities it needs to do its business, and on the type of organizational model selected for the business or enterprise. Existing SE competency models can be used to assist in determining the needed capabilities. An example is the INCOSE SE Competencies Framework (INCOSE 2010b). See the Roles and Competencies topic for more information on competency models.

As shown in Figure 1 below, management action on workforce development will be required if there are systemic mismatches between the competencies required to perform systems engineering roles and the actual competencies of individuals. Organizational culture may have a positive or negative effect on team performance and overall value added by the business or enterprise.

Need for Clarity of SE Approach, and Dangers in Implementing SE

In any organization where activities and skills are shared there is always a danger of silos or duplication. One of the purposes of SE is to reduce this risk – consider the interface or glue role (Sheard 1996), or the idea that “SE is good engineering with special areas of emphasis, … including interfaces between disciplines” (Blanchard and Fabrycky 2005).

Clarity on how the organization is doing its SE is important. Typically, implementing SE may be part of an organization improvement, so Kotter’s principles on creating a vision, communicating the vision and empowering the others to act on the vision are most relevant (Kotter 1995). The way an organization chooses to do systems engineering should be part of the vision of the organization – and must be understood and accepted by all.

Many of the major obstacles in systems engineering deployment are cultural (see Culture).

Systems engineering can make a very powerful contribution to the organization’s quality goals. Embedding SE principles, processes and methods in the organization’s quality management system means that senior management and the quality system will help embed systems engineering in the organizational business process and make sure it is applied [(INCOSE 2010a), (ISO 2008) and cross ref part 1?].

One of the lean enablers for systems engineering (Oppenheim et al. 2010) is "Pursue perfection". The means of improvement at business or enterprise level is discussed in detail elsewhere, but the starting point has to be deciding the systems engineering capabilities the organization wants.

A business or enterprise is a system – and systems engineering is one of the functions that system may need to perform. The specific requirements for the SE function can be derived from understanding what the overall system (the organization) needs to do, and from the relationship between SE and other functions within the organization at different levels. So there has to be a tailored solution to an organization's SE requirements given the unique set of purpose / scope / context / capability / culture of each organization. Also, organizations change over time (learning, improving or losing capability) and so the balancing of SE with everything else keeps changing.

Balancing the need for a systematic and standardized approach to SE processes, such as defined in models and handbooks, with the flexibility inherent in systemic thinking is critical. Systems thinking helps the organization understand problem situations, remove organizational barriers and blockers, and make the most of the organizations technical capabilities (see Beasley 2011 for example).
