Product-oriented design approaches tend to move directly from a specific ICED11 3 product idea to an overall product solution, therefore, addressing fewer design states than problem oriented ones.
This is illustrated in Figure 2. Figure 2: Different design strategies after  Identification of the stimuli of product development  and proposition of the development task typically mark the end of the policy or product planning stage, which leads to the elaboration of the design problem, resulting in a problem definition and a set of requirements which finalise the task clarification stage.
In the conceptual design stage the required functionality is transferred into a design concept, which is detailed and refined within the detail design stage, resulting in a full description of the product, so as to enable production . As a design task is widely seen as an ill-structured problem, the development process cannot easily move from the problem to a solution . In the progress of exploring the potential solution s to the given design problem, certain features and constraints of that potential solution typically lead to a reoccurring redefinition of the problem space.
This is usually referred to as co-evolution: the stepwise increase of knowledge about the addressed problem parallel to the developed solution, i. This repetitive moving back and forth between problem and solution is not represented in Figure 2, nor are the various iterations, which typically occur in the design process.
While problem definitions mainly consist of textual descriptions of the needs, requirements or constraints, design models addressing the solution are rather focused on specifying and visualising characteristics as well as evaluating, analysing and simulating properties of a potential product solution. As this is a major difference between modelling approaches, design states are regrouped prior to a more detailed analysis into problem states and product states.
Within these generic design states, the corresponding modelling approaches can be compared across disciplines throughout the entire development process.
Regarding the used code, symbols etc. Literature analysis Wynn and Clarkson  distinguish between analytical, abstract and procedural approaches to product development.
Analytical approaches do not address the entire process of product development, but rather focus on specific steps or individual activities in the overall process. Abstract approaches typically describe product development on a high level of abstraction which allows application in a wide range of situations.
They are less focused on specific disciplines and do not provide specific guidance in the product development process.
Departments and Centres
Procedural approaches on the other hand are more focused on the development of a product in a specific discipline and address the concrete steps and activities within the different phases in great detail. They are typically represented in design methodologies and provide a systematic approach consisting of phases and distinct design activities typically including the proposition of corresponding design models.
The combination of process and proposed design models enables a detailed analysis of the design states.
In electrical engineering, design methodologies, thoroughly capturing the development process, are rather scarce. Electrical engineers state, that design methodologies in electrical engineering until recently have rarely been an issue. With the strong increase of digital electronics and expensive wafer- technology, wherein the systematic planning of the different manufacturing processes e. Design methodologies in building design covering the entire process tend to originate from project management [26, 14].
Literature from architecture typically only addresses the development process up to the point detail design begins and the concept is handed over to civil and building services engineers.

The VDI guideline  introduces a process model based on mechanical engineering, but also addresses electrical engineering and software design, which is why it can be regarded as a rather interdisciplinary approach. Zeiler and Savanovic  and Cross  both propose approaches combining design methods from various disciplines Cross mainly from architecture and mechanical engineering; Zeiler and Savanovic from German, Dutch and Anglo-American design literature and systems engineering which can also be regarded as interdisciplinary approaches.
Identification of design states Table 1 illustrates individual design methodologies, which propose design models corresponding to the individual design states, divided between problem and product states.
Design states addressed in each discipline — generic design states — are highlighted in bold. Individual methodologies often address additional design states, which do not occur in other methodologies in their own discipline or in that of others. Those can therefore not be regarded as discipline-specific or as generic, and therefore are not presented here.
The design states of context analysis and project proposal cannot be classified as either product or problem state, as they address a problem as well as a potential solution.
The succession of individual design states presented below varies in some methodologies, up to the state of requirements specification. The presented order represents a tendency for the succession proposed in the individual design methodologies.
Typically this includes the analysis of the overall function which is broken down into basic sub-functions. Table 2 gives examples of typical discipline-specific design models representing these generic design states.
Regarding the generation of production documents, a speciality can be found in software design: While in other disciplines, the development process and the production process are typically sequential — requiring the creation of specific documents to enable manufacture of the product — in software design the product i.
For that reason, there are typically no production documents proposed in literature from software design. VDI guideline  in software development, usually refers to the product manual.
VDI 2221 - Systematic approach to the design of Technical Systems and products
A very common example of function modelling in mechanical engineering and mechatronics is a function structure, presented as block diagrams a or hierarchical trees b. Function structures often differ in the level of detail and types of the proposed basic sub-functions in the different design methodologies. A hierarchical tree illustrates the overall functionality circle A in b which is decomposed continuously into sub- and auxiliary functions circles B, C, E and F. The VLSI approach  in electrical engineering proposes a variant of such a hierarchical tree, wherein decomposition is repeated until basic sub-functions circles D, G, H and I are found, which can directly be fulfilled by re-usable electrical functional devices e.
In software design Kruchten  proposes the creation of use case schematics, which indicate a flow of events, to be enabled by the program, to specify and elaborate the required software functionality.
An actor starts a request, which the program has to process and link with other requests c. Use case schematics share certain aspects of a flow chart including actors to request the functionality i.
Scrum  on the other hand simply distinguishes between main- and sub- functions to be fulfilled by the software, which are represented textually and divided into different sub-documents. In building design the elaboration of the required functionality can be a detailed analysis as presented in d.
It can be regarded as a form of product functionality specification as it illustrates the material flow respectively, the flow of people between functional elements in this example individual rooms are allocated to specific processes: storage, WC, etc. The thickness of the connecting lines indicates the quantity of the flow between spatial areas, which can be used to arrange them optimally in a building .
Table 3 shows the categorisation and comparison of the exemplary design models. According to interviewed designers, the problems in understanding design models across disciplines originate mainly from the used code and symbols, discriminating crucially from each other due to the different perspectives dominating in each discipline.
Although the generated design models share the purpose of modelling the required functionality, their focus is rather different. For instance, function structure and function tree both illustrate decomposition into sub- or auxiliary functions, however, signals or energy flows are only represented in a function structure.
ICED11 9 Design models in software design typically address a higher level of abstraction e. For obvious reason, in software design and design of electronics, there is no flow of materials, only of energy and signals. Nonetheless, signals cannot exist on their own, but in some variation of energy and are channelled through materials or waves which may provide an approach for integrating the different discipline-specific perspectives.
