Engineering Design Reviews in New Product Development

A design engineer is responsible for an entirely designed product to be delivered to meet the product specifications. Design reviews are an essential component of the design process of new product development. A cross-functional team must be formed to provide input on the product. This team should be comprised of members with different areas of expertise: engineering, marketing, sales, manufacturing, sourcing, and quality. The team is guided to review the current design and provide feedback to improve the product. The original product specifications are considered to ensure the product meets those guidelines. Design reviews are held at different milestones throughout the project to ensure the design stays on-track with the product specification.

Quality and reliability of the new products are evaluated in the design reviews. Purchased parts and self-manufactured parts must be held to certain quality level specifications set by engineering to ensure a quality end-product. Life testing, as well as other validation testing, authenticates the design before the release of the product for sale. Certain agencies, such as Underwriter Laboratories (UL), Canadian Standards Association (CSA), and the European Commission (CE) provide standards to test products for safe consumer use. Third party test laboratories are used to certify the product to these standards.

Can the product be manufactured and in a profitable fashion? The new product must be thoroughly planned in order to be manufactured efficiently. Design for Six Sigma should also be utilized to ensure quality lean manufacturing. Cost out initiatives are used to increase profit margins. Quality must be priority during cost outs to ensure warranty costs do not arise due to a lower quality end product.

In the design review process, a safety assessment of the product is completed. The team should evaluate any safety concerns regarding the current design in manufacturing and for the finalized product. If the product does not meet safety requirements, the team needs to find ways to modify it. Considerations need to be made to determine whether or not the validation testing will prove that the product design is safe for the end user.

Design reviews need to be focused around the original product specifications set up by the project. The cross-functional team should have periodic design reviews through the life cycle of the new product development. Frequent reviews prevent “scope-creep” and aids in keeping costs of development on budget. The team meetings need to be kept on topic, and all ideas need to be thoroughly examined by the team. An action item list, which documents all steps throughout the life cycle of the project, needs to be kept up to date to list all ideas and concerns from the design review meetings.

The design engineer must keep the project on time and on budget. Keeping the design reviews on topic with the team improves the effectiveness of improving the design. Scoring the different ideas on improvement of the design weeds out the ideas that should not be incorporated. Design reviews are a necessity in new product development and need to be utilized effectively and frequently.

What Do I Need to Operate a Digger Truck?

One of the most extraordinary three-in-one machines of this century is a digger derrick truck. This is a very versatile piece of equipment since the truck has three different applications that include: excavating holes, hoisting heavy objects, and lifting workers to various heights. So it performs the functions of an auger drill, mobile crane, and bucket truck combined into one powerful vehicle. Because of this, no one is allowed to operate this monstrous machine without possessing a special license in order to ensure the safety of both the driver and the people close to the equipment. Besides possessing the correct license, all of the rules formulated by the state and federal government as well as the company itself must be followed.

Driving Qualifications

Since the digger derrick is more complex to maneuver than the normal hydraulic boom truck, drivers need to have adequate training and attend the proper educational programs before being allowed to operate this vehicle, as it is far too dangerous to be driven by anyone lacking formal training. For this reason, OSHA and ANSI have created a compliant training program regarding safe operating procedures. This discipline encourages each driver to read, comprehend, and abide by the written guidelines found in the manual for procedures and tasks associated with any foreseen and unforeseen hazards. Having been prepared for the use of this vehicle, the skilled behavior of a driver will help prevent the occurrence of any severe work-related accidents.

The following things may be included on the practical evaluation once the training program has been completed: safety guidelines, OSHA regulations, unit inspection, correct driving on the highways, handling materials, and load capacity. Students will also have to apply the knowledge they have gained in the classroom and during “hands-on” training and take a physical road evaluation as well. Those who pass both examinations will receive their certification.

Drivers License

Driving a digger derrick requires a commercial driver’s license (CDL) if the Gross Vehicular Weight Rating (GVWR) is 26,001 pounds or more’ however, it is legal to operate the vehicle without a CDL if the truck’s GVWR is less than 26,000 pounds. As stated above, in order to obtain a license, the driver must undergo a written and practical exam. A licensing program starts by theoretical instruction in a classroom setting which is directed towards passing the practical evaluation to obtain a CDL permit. This permit allows a student to operate the equipment during their training class.

Once the student has acquired enough training to handle the machine safely and comfortably, a Class ‘A’ CDL will be issued.

Rules and Regulations

Since there are many cases where accidents have occurred while operating digger trucks, OSHA has published new guidelines for handling derricks. The new rules contain the requirement that all operators must obtain certification to drive these vehicles. In short, drivers must not only be trained but must also be certified. Employers are required to send employees to a third party training facility for certification. Conforming to OSHA’s safety standards will enable both the employer and employee to remain safe during the job performance.

Driving mobile machines with auger drills requires certain qualifications. This is not a simple machine that can be run with no experience at all; operating these vehicles requires months of training. It requires a Class ‘A’ commercial driver’s license and conformance with all state and federal rules and regulations. All of these things must be complied with to ensure that safety is given the highest priority. It all becomes a part of what is needed to operate a digger truck!

Graffiti Art – A Solution to Urban Decay?

Graffiti is a social expression as much as one would associate it as a personal one. Many people who are opposed to graffiti, see it as a reflection of social breakdown, rebellious attitude and a lack of sense of citizenship.

Should graffiti writers be allowed to do anything they wanted? I am a keen believer that ‘controlled graffiti’ has more benefits than negative impacts on the society. It is true that vandalism is not welcome in the society. However, there are many graffiti writers who treat graffiti art as a form of community beautification. By community beautification, I consider graffiti art in urban ‘dead spaces’. They help to spice up abandoned urban blight and educate the public on social issues.

Graffiti art is a contrast to other forms of public art. Art form that requires no gallery hierarchy and no merchandizing and commercial hustle. There is a feeling that public advertising is the real cause of urban decay. Too much commercialism has caused the declined of public interest towards political and social concerns.

Graffiti art is a vehicle for people to connect with. It is the perfect platform for urban dwellers to know what is going on with a city. Looking at the writing on the wall, you can tell what are the social and political problems that are happening in the country.

Graffiti art is the ultimate expression of artistic democracy. It is a true reflection of the culture that it comes from. Graffiti artists send to the public a strong message-we should be more concern with social issues amid the influx of negative commercialism.
