Understand DOT in a nutshell
| ||
DOT advocates a concept development process that responds to the challenge of 'One Planet Living'. This development process evaluates whole-life impacts for users, the business, the wider society and the planet. A high-level description of this development process is described on this page. However, we recommend this content is better read by printing the PDF version. On this page: | ||
What is the problem? | ||
Many businesses currently rely on the materials & energy cycle shown in the diagram below: Key points
In order to achieve long-term profitability, businesses will need to use materials and energy much more efficiently. Examples include the sale of services rather than products, and reconfiguring the business operations so that ‘man-made’ materials can be re-used indefinitely, rather than being ‘consumed’ and then ‘wasted’. | ||
What is the answer? | ||
The development of successful products and services requires informed decision-making at the concept stage, because it can become prohibitively expensive to make changes later on. Design concepts that reduce environmental impacts, increase profits and improve the user experience will be readily adopted. In contrast, design concepts that compromise profitability or the user experience are unlikely to make it to market. The performance indicators used to judge and select new concepts should cover ‘whole-life’ impacts for users, the business, the wider society and the planet. Importantly, the rising costs of commodities, fuel & electricity should be considered when evaluating future profitability. The remainder of this page summarises the specific activities that should be performed to deliver a lead design concept, together with evidence that it is better across all the performance indicators. Furthermore, a case study of the through-letterbox design of the new BT Home Hub is presented, which reduces business costs, reduces vehicle miles and increases customer satisfaction. | ||
How should products & services be developed? | ||
Best practice principles for each of these phases are given in the bullet points below, then each phase is considered in more detail further down this page. | ||

1. Explore
2. Create
3. Evaluate
4. Manage

Explore | ||
The 'Explore' phase of the design cycle is about understanding the user and business stakeholders, the real-world scenarios of use, and the flows of materials and energy across the whole-life of the product. These findings should be drawn together to determine ‘What matters?’ for performance indicators that cover the users, the business, the wider society and the planet. Specific activities are shown in the 'Design wheel' below. Choose benchmarkThe stakeholders, real-world scenarios of use, and flows of materials and energy are considered relative to a benchmark. Choosing this benchmark is the first activity within ‘Explore’. The current product (or an equivalent competitor product) could be used as a benchmark. However, if you wanted to develop a breakthrough product, or shift from a product to a service, you might choose multiple existing product/service combinations that provide equivalent benefits to the user as the concept being developed. Create stakeholder mapIdentify the key players who have something to gain or lose from the concept being developed, covering the users (e.g. purchasers, installers, end-users, supporters, maintainers); the business (e.g designers, manufacturers, retailers, refurbishers); and the wider society (e.g. regulators and shareholders). Market segmentation and personas can help to characterise the different types of users. Describe user journeysDescribe the real-world scenarios of use according to the tasks that the user performs across the whole-life of the benchmark product. A Framework for user tasks is shown further down this page, which includes purchase, installation, use, end-of-life triggers and subsequent actions. Create a map of impactsUse an impact map to show how materials and energy are used across the whole-life of the product. An example Map of impacts is shown further down this page. Review performance indicatorsA Framework of performance indicators is shown further down this page. Use this framework to prioritise the issues and determine ‘What matters?’. | ||
Framework for user tasks | ||
The diagram below shows the tasks the user may perform across the whole-life of a consumer product. | ||
Example map of impacts | ||
As a basic example, the diagram below shows the flow of materials and energy for a letter that is printed, sent, delivered, read and then discarded. Given a particular real-world scenario, numerical analysis could readily provide the ‘carbon’ and ‘cost’ impacts to fill in the blank white boxes. See the Impact map section within Apply it for more information. | ||
Framework of performance indicators | ||
This framework matches a set of performance indicators to the corresponding stakeholders, across the whole-life of the product. The whole-life of the product typically involves the stages:
For most current products, the user ‘Passes it on’ by throwing it in the bin, and ‘Reprocess it’ represents storage in landfill. However, most solutions to address ‘One Planet Living’ require much more refurbishment and recycling within ‘Reprocess it’. The stakeholders should typically cover the users, the business and the wider society. In addition, many businesses rely on the natural capital provided by the planet’s ecosystems. So, the stakeholders can be categorised according to:
The framework shown below describes the performance indicators that are relevant for these stakeholder categories, across the whole-life of the product. Use this framework as a prompt to help consider the issues and determine ‘What matters?’. Many of these performance indicators are inter-related and overlapping. For example, refurbishing products typically reduces the 'Depletion of scarce resources', 'Energy use' and 'Waste impacts'. Improving the 'User experience' will also improve the 'Brand equity' and reduce the 'Costs' of product support and consumer returns. See the Performance dashboard section within Apply it for a more detailed description of these performance indicators. | ||
Create | ||
The 'Create' phase of the design cycle is about developing concepts in order to make things better for the ‘priority’ performance indicators that were identified within the ‘Explore’ phase, which cover ‘whole-life’ impacts for users, the business, the wider society and the planet. The specific activities are shown in the 'Design wheel' below. Review potential suppliersConsider existing and alternative suppliers according to the environmental impacts of the goods they supply, and the behaviour of their business as a whole. Consider both incremental improvements and new technologies that offer step-change improvements. Maximise leverageLook for opportunities where the product can enable substantial positive impacts. Example opportunities include ‘home energy’, ‘personal transportation’ and ‘user health, safety and well-being’. Stimulate ideasDon’t get stuck in old ways of thinking. Start by trying to get as many ideas as possible, and avoid making judgements too early on. Encourage wacky ideas, look for inspiration in unusual places, and ask ‘How else could it be done?’. As a stimulus for ideas, use the Impact map (described earlier) to look for opportunities where the ‘waste’ could become ‘food’ for another business, and consider how ‘end-of-life’ triggers within the User journey could be resolved in a manner that minimises environmental impact while maximising revenue for the business. Develop conceptsGroup related ideas together and refine them to produce descriptions &illustrations of concepts that can be compared against the benchmark. Aim for at least one ‘safe’ concept and at least one ‘crazy’ concept. However, make sure you seek out and resolve the unintended consequences of the concepts, by systematically considering all the user and business stakeholders, real-world scenarios of use, and the flows of materials and energy that were identified within ‘Explore’. Make prototypesUse drawings and models to communicate the concept and enable it to be tested. | ||
Evaluate | ||
Evaluate the concept(s) to determine whether they are better than the chosen benchmark, for the ‘priority’ performance indicators that were identified within the ‘Explore’ phase. These performance indicators should cover ‘whole-life’ impacts for users, the business, the wider society and the planet. The specific activities are shown in the 'Design wheel' below. Estimate people, profit and planet impactsUsing the Framework of performance indicators (described earlier), judge whether the concept is better, worse or the same as the chosen benchmark, for each row and column of this grid. A simplified example of the outcome is shown below. A performance dashboard should be used to help capture these evaluations. Use the stakeholder map, user journeys and impact map as prompts to ensure the evaluation is complete. See the Performance dashboard section within Apply it for more information. Review uncertaintyFor all of the estimates involved in a concept evaluation, consider which ones critically influence the decision-making, and consider whether these estimates are accurate enough for their purpose. Present evidenceUse the performance dashboard to summarise each concept by presenting the overall judgements of the Chief 'X' Officers: CMO, CFO, CTO, COO, CSO (Marketing, Financial, Technical, Operations, Sustainability). | ||
Case study: BT Home Hub 4 | ||
The new Home Hub 4 has been designed with a slim-line shape and spring-loaded feet so that it will fit through most letterboxes.
The performance dashboard shown below evaluates this ‘slim-line’ Hub 4 by comparison against against a ‘hypothetical’ Hub 4 that is a more typical ‘box-like’ shape. After the end of their useful lives, this evaluation assumes that the letter-box design means that more hubs will be posted back to BT by the consumer, which will increase BT’s ability to satisfy consumer demand by providing refurbished hubs.
