It is important to make it possible for users to program software without having to write code. This relies on visualisation of the problem in a similar way to modelling. So to make this approach possible it's necessary to look to develop free models and modelling tools for use over the Web. These can be used for teaching, collaborative problem solving, management decision making, and environmental modelling. The techniques used to build these models are often called Semantic Web or Web 2.0. This involves providing the kind of software over the Web that is already available on individual computers, and using this for sharing of information worldwide. These kind of models change in response to the user, perform calculations, and range from dynamic computer aided design (CAD) type representations to hierarchical information explorers.
More generally a new approach is required to software creation. This approach should involve developers creating software systems that enable users to perform high level programming and model the problem for which they are the experts. This is an alternative to the provision by developers of modelling solutions that try to provide an out of the box solution that just needs 'tweaking'. Such systems are impractical considering both increases in complexity of manufactured products, and of software systems themselves. People like to work on their own solutions providing they are computer literate and confident they have domain knowledge that the developers do not possess. This is true for software development in general, not just in the domain of engineering.
