Undertaking the steps to construct a PIOT that would represent outputs of the sectors within the complex catchment system, a tremendous amount of data is required, along with the contribution of multiple experts. To overcome this challenge, a IDEF0 was introduced in the schema. IDEF0 (a compound acronym deriving from Icam DEFinition for Function Modelling, National Institute for Standards and Technology, December 21, 1993) is a method designed to model the decisions, actions and activities of an organisation or a system. It has been applied, but is not limited, to topics such as strategic planning, hybrid systems design and business process reengineering (Feldmann, 1998) and has proven useful for handling complexity and bridging communications gaps between various actors involved in a system. Recent research (Settanni et al. 2015, 2014; Šerifi et al. 2009) highlights the applicability of the method across disciplines and sectors for the development of modelling approaches to product service systems to measure performance and outcomes of asset systems, as well as designing software packages.

Typical motivations for process modeling are forming of an “as-is” model of the current process, analysis of the current process, forming of the target “to-be” process, and, to have these all results as a common communication tool for training and improvement purpose. In the FutureHome project the delivery chains were modeled and analyzed using the IDEF0 process modeling method. IDEF0 is a method designed to model the decisions, actions, and activities of an organization or a system. IDEF0 was developed for analyzing and communicating the functional perspective of a system. Effective IDEF0 models help to organize the analysis of a system and to promote good communication between the analyst and the customer. IDEF0 is useful in establishing the scope of an analysis, especially for a functional analysis. As a communication tool, IDEF0 enhances domain expert involvement and consensus decision-making through simplified graphical devices. As an analysis tool, IDEF0 assists the modeler in identifying what functions are performed, what is needed to perform those functions, what the current system does right, and what the current system does wrong. Thus, IDEF0 models are often created as one of the first tasks of a system development effort. (http://www.idef.com).
Capability Maturity Model Integration (CMMI)

An important concept to be considered is the relationship between GPs and PAs. Consider the PAs shown in Table 3.1 and the GPs shown in Table 3.4. Based on their titles alone, one can see that there are PAs that are closely related to certain GPs. For example, the Configuration Management (CM) PA will, if properly implemented, satisfy GP 2.6 Manage Configurations. Similarly, the Process and Product Quality Assurance (PPQA) PA can satisfy GP 2.9 Objectively Evaluate Adherence. The detailed relationships among the GPs supporting GG 2 and GG 3 and PAs are shown in Figure 3.3, using the IDEF0 notation. The graphical language of IDEF0 contains two basic constructs: boxes, representing activities or functions; and arrows, representing inputs, controls, outputs, and mechanisms. The diagram structure supports the presentation of increasing levels of detail for each activity box. IDEF0 diagrams are built by connecting boxes and arrows representing inputs (connected to the left side of the box), controls (connected to the top), mechanisms (connected to the bottom), and outputs (connected at the right side of the box). A control arrow describes something that guides, determines, or constrains the function (e.g., a plan), whereas the mechanism arrow represents the resources that enable the function to operate (e.g., tools). Boxes and arrow segments are combined in various ways to form diagrams. Each box can be further decomposed into subfunctions with their own set of inputs, controls, mechanisms, and outputs. Such decomposition starts with a context diagram that represents the highest level in the hierarchy and may result in hierarchically arranged layers of IDEF0 diagrams.

Manenti et al. (2019) conclude that IDEF0 is very well suited for modelling systems engineering processes as it eases the complexity of applying and tailoring processes. As a modelling tool, IDEF0 can help the analyst identify the functions performed by a system and then determine what is required to perform those functions. The IDEF0 model of a system consists of an ordered set of boxes and the arrows associated with them. A box represents a function of the system and an arrow indicates an interface. A box contains an active verb or verb phrase to denote a function. According to the IDEF0 definition (U.S. Air Force 1981), a function is an activity, transformation, or process that receives some input and converts it to output by some mechanism and is subject to some controls (see Figure 6).
A variability taxonomy to support automation decision-making for manufacturing processes

An IDEF0 diagram describes what a system does, what controls it, what things it works on, which means it utilizes to execute its functions, and what it delivers. The components in the IDEF0 are: inputs (I), controls (C), outputs (O) and mechanisms (M). Input data or objects are transformed by the function to produce the output. A control is utilised to address the work in the process. Plans, standards and checklists are all forms of control. Mechanisms can be staff, tools or equipment employed to carry out a task. The variability parameters identified from Section 3.1 contributing to variability in manufacturing processes are associated with five key attributes of the task: inputs, outputs, strategy, time and requirements. Strategy and Time are defined as forms of control that determine the way the tasks were executed, and Requirements refer to the mechanisms that enable the task to be performed.

Consequently, IDEF0 has been used for supporting the modeling of Engineering Management systems or processes in diverse and specific domains such as Manufacturing Systems (Pawlewski, 2014), Industrial Engineering (El Najjar et al., 2014), Business Process Re-engineering (Bevilacqua et al., 2012), Plan-Driven Project Management (Sullivan, 1991), and Strategic Planning (Waissi et al., 2015). In the domain of Software Engineering, IDEF0 has been scarcely used (Imran et al., 2010) and in the specific problem of modeling agile Project Management practices its study has been almost null (Galvan-Cruz et al., 2017).
