Design for success is based around using human centered design specifically in the field of engineering. It focuses heavily around engineering projects such as power plant management systems and fighter pilot control systems. However it follows and embraces the principles of human centered design and uses this to inform much of the design while laying out guidelines and rules to allow human centered design to be used in almost any circumstance.
It splits the process up into a number of different phases each of which in turn has its own particular elements and smaller phases and covers everything from the initial research which it terms the naturalist phase through to the sales phase.
Each of these can easily be traced to IDEO’s same phases. These will be shown, Naturalist = Listen and this even stated in the text itself. The next phase the marketing phase represents
This books viability, acceptability and validity relate matched loosely to IDEO’s three lenses of human-centered design desirability, feasibility and viability
Viability is what is financially viable, while design for success makes this into a more involved question and looks deeper into the matter as the book would.
Feasibility “what is technically and organisationally feasible” is acceptability IE will the organisations make use of and benefit from the system as intended.
Desirability “what do people want?” is validity i.e. does it solves the problem
ALL human centered design products MUST hit all three according to IDEO and Design for success.
The two books also feature a number of phase while IDEO combines some into a single phase, design for success strings them out into more varied and in-depth stages.
The naturalist phase = Hear, research into the field using all kinds of human centered methods, interviews, questionnaires, experts and existing literature.
The marketing phase = Create, introducing product concepts to users, through again questionnaires, interviews scenarios, mock ups and prototypes.
The engineering phase = deliver developing a final design of the product or systems / begin to realize your solution through rapid revenue and cost modelling, capability assessment and implementation planning
While the two methods are roughly similar there are some key differences. Possibly arising from the different fields and time periods the literature I taken from. Hear and naturalist are pretty much the same, it’s when you go to the next phase differences start to appear. Marketing/create, here design for success is obviously working in a more industrial realm with less room for mistakes as prototypes are developed earlier on to test technical abilities which are also developed alongside and parallel to the process, IDEO sees that as a less important part of the process,( maybe because of the different tech levels at the time of writing) ALSO IDEO is more about getting a score of workable solutions and trying them all out to some degree while design for success if looking for one or two solutions which work alongside their other designs.
Ultimately the differences come from being so far apart in time and what they are designing for. While both use the same principles they are targeted at different fields and with different technology so require different work around to make them effective for that particular field. Design for success ironically while being about human centered design is more about the process and design in general while the IDEO tool kit is much more human centered. The time investment for following either set would be very different IDEO aims for a quick (relatively speaking) turnaround while design for success is obviously looking at long projects which are relatively “clean” problems to solve.
This means that rather than blindly following the HCD rules I will need to take into account this difference when developing my own HCD rules for the creative project artefact.
