The Engineering Outsourcing DebateThe impact of engineering outsourcing on the global economy is a discussion of keen interest.
Consistent reporting of problematic engineering graduation data has been used to fuel fears that America is losing its technological edge.
Typical articles have stated that in 2004 the number of undergraduate engineers are: United States 70,000 India 350,000 China 600,000

• capable of abstract thinking and high-level problem solving using scientific knowledge.• thrive in teams, • work well across international borders, • have strong interpersonal skills, and are • capable of translating technical engineering jargon into common diction.
Dynamic engineers lead innovation.
The majority of dynamic engineers have a minimum of a four-year engineering degree from nationally accredited or highly regarded institutions.
DYNAMIC ENGINEERS
may possess engineering fundamentals, but not the experience• lack experience or expertise to apply this knowledge to larger problems.
These individuals are typically responsible for rote and repetitive tasks in the workforce.
Transactional engineers often receive associate, technician or diploma awards rather than a bachelor’s degree.

So are we really dynamic ?
Do 80% of us become transactional over the course of our career?
How to find the dynamic impulse ?
Doesn’t computers give us an advantage ?
A window of opportunity
Are we talking the same language?
Is the writing on the wall ?

Where did we go wrong?
Defaults
Delegated quality to third party
WYSIWYG WYPIWYG
Anecdote of the 3 dp setting
Graphical Dyslexia
Lack of Visualisation
Shoulder-Shrugging Syndrome

Poor benchmarks

Electronic Calcs
A set of pro-forma calculation templates to be used by engineers
It’s also a culture shock
A MS Word document conforming to QA/QC requirements of the project/company
It’s about how to give engineers the techniques to be more effective.

Electronic
My experience of Electronic Reports- Clients/third party impressed with the standard.- Engineers more productive, energized, enthusiasm.- Engineers are working in the same direction. - Creates a stimulating, open and competitive environment.- Significant savings in project hours.- Helps engineers establish a benchmark for the future.- Helps lead engineer control the project.- Redresses the balance in engineer/designer training.
- Training is on-the-job.- It is a refreshing cultural revolution for engineers.- It’s about positive techniques.- Puts calculations on a par with the drawings as a deliverable.
The Benefits
MS Word
Development of consistent corporate procedures.
Increasing the engineers productivity in an era of dwindling resources.
Increasing the engineers’ skill base.
Improvement in quality of calculations.
Easier to check, easier to ask questions.
The report style can be fixed, communicated and demonstrated.
Substantial savings in engineering time,
Enables delegating of separate sections to different engineers.
The Road to the Future
Be dynamic
Be innovative
Improve your technological skills
Align knowledge with technology
Align technology with your experience
Take responsibility for quality
