There are good reasons for wanting to alleviate middle-age hearing loss (HL):
- People with untreated HL are twice as likely to feel left behind in job and salary prospects[1a].
- People with untreated HL are 2.5 times more likely to suffer major depression disorders[1b].
- Middle-age HL is a key risk factor that contributes 9% of dementia.
- Untreated HL costs the UK £25.5 billion (US$32 billion) each year.
- Untreated HL costs the world community at least US$750 billion each year.
Yet, most people with HL do not get hearing help. Here is why.

Respiratory care ventilator for pandemic emergencies, such as the COVID-19 Coronavirus. The concept is low cost and mass-producible from off-the-shelf components that are readily available at national levels. The Ennomotive Open Innovation Hub for Engineering has developed the concept into a clinically effective Volume Control SIMV ventilator. The development stages documentation is published open source in Github. Ennomotive can provide interested producers with the final documentation and conformity assessments to medical device standards.
The individual device has a component cost of just £400 (GBP), or Euro460 or US$500. Continue reading “Emergency Ventilators”
Determining the appropriate level of details in the QFD House of Quality is a double-edged sword. On one hand, people in the team can lose oversight if the resolution becomes too fine, where the wealth of details makes the House of Quality so complex that we can no longer visualise the rationale behind our design decisions.

The aim of NPD project management is to develop the product within time and budget constraints, while also assuring that the design work is complete. There are risks from a NPD team not recognising an over- or under-design. Releasing a new product late and over budget, due to a tendency of making endless low value-adding refinements to the design, is practically just as bad a releasing a sub-standard design too early. Continue reading “Are we there yet?”
The House of Quality (HoQ) weightings concept is about reflecting the organisational context, by accordingly emphasise or de-emphasise the development focus on individual requirements. The context can include the commercial competitive situation, strategy, and the foreseeable degree of difficulty from limitations in capability and capacity. The exacting measures used in the ‘what context’ and ‘how context’ can be varied for different markets and organisations. Continue reading “House of Quality Context Weighting”
Although the founding of QFD is based on evaluation matrices, as containers for the planning activities, the concept of QFD can in fact be implemented without using any single matrix at all. The spirit of QFD lays in a team-based process for maintaining visibility and integrity in the VOC, when translating the characteristics in one domain into characteristics in another domain. Continue reading “Shorthand QFD”
The product life-cycle functions within an organisation can be thought of as operating on 3 working platforms. The model indicates that of the ideas on the ‘generate’ platform only about 1 in 10 gets prioritised for progressing into development. Continue reading “Organisational Modes”
Solution space is abstract, multi-dimensional and non-convex. The space contains known and partially explored optimum solutions, which are illustrated here as hilltops. Areas of solution space are inaccessible to us, either because someone else have established the Intellectual Property Rights to it or because it represents a ‘void’ in our own design or production capabilities – i.e. the solution depends on a materials or technique that is outside our organisation’s skills set. Continue reading “Navigating solution space”
Decision making is the forming of a causal argument that a chosen alternative will result a certain future outcome. The quality of a decision is largely dependent on the accuracy and relevance of the information on which it is based – as well as being free from subjective bias in reflecting the true needs. When poor quality or biased evidence is used for decision making, the proposed alternative will risk producing an ineffective or adverse outcome. Standards, such as ISO 9001 on quality management and ISO 16355 on QFD, therefore calls for factual decision information. Continue reading “Evidence-based decision making”
People are a particularly dynamic resource. Firstly, they are extremely flexible and adaptable, compared to a machine. Secondly, the individual person has an independent mind, which is sensitive to its environment. People’s abilities, concentrations and commitments vary continually. People need to be equipped with the skills, knowledge, support and motivation necessary to perform their functions within the system well. People also need to be aware of the organisation’s values and objectives, and understand how they themselves contribute to meeting these. Continue reading “People in systems”
