Verification Strategy

For this project a number of verification strategies will be used to

ensure that the best possible design, with the greatest design

potential is chosen for further development and production.

The verification strategy must be chosen that, while it delivers

enough data that a reasonable choice in design can be made, it is

not so vigorous that the process of verifying which design to

proceed with negatively impacts on the rest of the design process. It

is important to find this balance to ensure the project is completed

efficiently and to a standard that is acceptable.

To ensure a suitable and robust strategy was chosen for

implementation, research was first carried out to identify a suitable

approach to verify that out of a number of concept designs only the

best will be chosen.

This research was carried by searching the internet to find suitable

sites. Sites visited included Wikipedia, www.eetimes.com,

www.engineeredsoftware.com and www.cs.york.ac.u. These sitescover a variety of disciplines, from the computer and automobile

industry to a rough guide on design verification strategies.

They were chosen to give both a good rough outline of how a

verification strategy should be carried out, but also to see how such

a strategy is implemented in other complex projects, such as

computer processor design, and in similar products to the project

like the automobile industry.

Other research included looking at previous projects carried out and

accessing how well their verification process where in choosing the

best designs. These projects included work carried out by the author

individually and in groups, as well as works undertaken bycolleagues individually and in groups.

From this research a number of verification strategies have been

identified as being suitable for use in this project. They include a

mix of strategies to enable a shotgun approach to verification and

ensure that a good result is achieved. These strategies have a mix

of group, individual and self examination of the concept designs.

The strategies chosen are peer review by classmates and peers,

Weighted Objective method, Professional Critique and group review

by the medium of the internet.

To ensure a good result in the verification process each review has

been chosen to enable good data to be gleaned on particular

aspects of the design. For example the aesthetics of the project do

not need to be reviewed under the weighted objected method, as

aesthetics taste vary from person to person, so a simple peer review

will just as readily show which design is most aesthetically pleasing

to the majority of people.

Each verification technique will hence provide good data on

particular aspects of each individual design, while also covering a

small variety of different design aspects.

Professional review

The professional review is included to help determine the best

technical qualities of each design. This will help show the best

arrangement of devices used in locomotive operation and the best

technologies to implement in the design. He will also be invited to

propose alternates to help improve the design at this stage in the

projects life. The following is an example table of the main aspects

of each design that the professional will be asked to review;

The designs will be evaluated against a number of different designcriteria, each aspect will be assigned a weight which will show thebest design, as well as showing the best features of each designwhich can be aggravated into a hybrid design, incorporating thebest aspects of each concept design.

This verification process will be carried out by the designer as wellas a number of volunteers to ensure good and accurate data and alarge range to help prevent statistical irregularities i.e. lots of peoplelike one design whether or not is technically the best.

Internet Review

The internet review will simply be another group and peer review,but with a much larger catchment area and with the possibility ofvast amounts of data. As the internet is not the most reliable ofsources, and the qualifications of those taking part cannot beverified it will be of most use to indentify the best design in generaland those the design with the most appealing aesthetics.Specific targeting of how takes part in the review can be undertakento improve the quality of data gleaned, but for our purposes this isunnecessary and wasteful, as adequate data can be reached by theother methods utilized in this verification strategy.

Each part of this review will show up the best aspects of each design

and will help guide the products further development during thecourse of the project.The different verification strategies taken signally will not provideenough information to overcome statistical anomalies but togetherthey will provide a very clear picture of the best design.
