5.2 The aims and principles of system engineering

The aims of systems engineering can be divided into those to do with its outputs and those associated with the process itself. As far as its outputs are concerned, systems engineering aims to ensure that:

  • the requirements of all the stakeholders are taken into account in engineering the system

  • the system, as engineered and realised, meets the requirements of stakeholders

  • the system, while meeting the req

4.7 Summary

This topic has examined the historical development of systems engineering and modern concepts of the subject. It has discussed:

  • the beginnings and early development of the subject as policy analysis

  • the use of systems engineering in organisations

  • the development of methodologies associated with information technology.

3.10 Systems techniques

The two systems methodologies provide a framework for the application of problem solving, analysis and design techniques. These fall into three groups.

  • Diagramming: ranging from single systems maps to complex flow charts. Diagrams of one sort or another provide a method of analysis, design and communication.

  • Modelling: simulation is used extensively to analyse the dynamics of an existing system and to predict the behaviour of a propos

Stage 5: Comparison of Stages 2 and 4

The objective of the comparison stage is to relate the conceptual model to the problem situation as depicted in the rich picture. The idea is to highlight differences between the two so that potential improvements to the problem situation can be identified.

4.19 Technologies and explicit knowledge continued

The following examples give a taste of what is now making the transition from research laboratories into commercial products. Large hierarchical information structures are extremely common, whether in libraries, organisational charts or websites. Displaying such large structures is a challenge, and since the user soon runs out of screen space, navigating them can be tedious. Screen 7 shows a system that uses animation and carefully designed graphical effects to give the impression of manipula

4.6.1 Connecting people to people

Compared to even five years ago (a long time in technology), tools for virtual meetings and workspaces are extremely common now in many organisations, who typically purchase specialist products rather than develop their own. Tools for virtual meetings really have to work smoothly or the results are immediately obvious, and can be very high cost (for example, one cannot afford for a meeting with an important client to ‘crash’). Organisations are therefore willing to pay for robustnes

4.4.2 Mapping across multiple communities of practice

In introducing the core concepts, we highlighted the perspective that ‘what counts’ as valuable knowledge is unavoidably shaped by the communities of practice to which the ‘publisher’ and ‘consumer’ belong. One makes situated judgements regarding the relevance of a new piece of information for oneself and others, and how to store or share it appropriately. One geographical metaphor conjured up by this perspective is that of ‘islands’ of local coheren

4.3.1 Mapping what we know

Knowledge maps are often one of the first knowledge management representations to emerge, in an effort to add value over the simple corporate intranet search which returns lists of ‘hits’ that are undifferentiated beyond a ranking in terms of keyword matches. Knowledge maps, like other forms of cartography, should communicate a ‘big picture’ by overlaying meaningful structure on to raw resources.

4.1.1 Mapping who knows what

One of the most widespread ways to represent what you know is to represent who knows what. This avoids the complications of codifying or storing the knowledge in great detail – you simply map the relevant people to a high-level taxonomy, leaving them to give contextualised answers when asked. Initiatives to provide corporate ‘yellow pages’ which map an organisation by what people know rather than by where they work, or alphabetically, have been reported to be extremely popular and

1.2 Pressing questions

In the late 1990s, when this unit was first prepared, if you surveyed the field of knowledge management technology you were assailed by technology vendors offering Knowledge Management Solutions. As we write in 2005 , an internet search on ‘knowledge management ICT’ will still return thousands of hits, but the ‘knowledge’ buzzword has faded in potency, the hype bandwagon has trundled on, and vendors now market the same products under business process banners which reflect gr

Engineering for the Earth
Young students are introduced to the complex systems of the Earth through numerous lessons on the Earth's natural resources, processes, weather, climate and landforms. Key earth science topics include rocks, soils and minerals, water and natural resources, weather patterns and climatic regions, wind, erosion, landforms, and the harvesting of fossil fuels all presented from an engineering point-of-view. (See the Unit Overview section for a list of topics by lesson.) Through many hands-on activiti

5.1 Review

One of the central aims of this unit has been to give you a sense of being part of an exciting educational development. We have therefore set the employment of teaching assistants in the context of the widespread growth of a new paraprofessional workforce across public services. We have noted the gendered nature of this workforce in schools, identified reasons why local parents in particular are attracted to working in schools, and highlighted the valuable contribution that teaching assistant
