Our Approach To Business

Business Model

Our company name reflects our business model. Corporate management and infrastructure don’t provide direct support to our clients. Our employees do. If we attract and retain the best employees in our industry, we will be successful. If we fail to provide a quality workforce, nothing else matters. We achieve our purpose and our business success through hiring and retaining the very best employees in our industry.

Stability

Sale of a company is potentially very disruptive to both clients and employees and might potentially dilute the focus on serving the long term interests of our nation, our government clients, and our employees. For this reason, we have taken action, through legal restrictions on ownership and sale of company stock, which prevent the sale of the company to outside parties. Stock is legally restricted to the founder’s family and company employees. This restriction ensures stability of ownership for our clients and our employees. This restriction also facilitates a focus on long term value.

For Exceptional Results
Purpose And Focus
The purpose of E3R is to support those who serve our country, and to do so in a manner that stewards the taxpayer’s dollars to maximize the long term value that we provide. While we must earn a profit to remain in business, our purpose is to support those who serve our nation. This purpose will always be our highest priority. Our intent is to build a company that will continue to benefit society even long after the founder has passed on and the initial employees have retired. Our focus is therefore to build long term value rather than short term gain.
 
Conflicts Of Interest

We provide program management support and SETA (Scientific, Engineering, and Technical Assistance) support services to the government. As a trusted agent for the government, we will not perform prime system development or be a subcontractor to a prime system developer. Roles on prime system development contracts are avoided because such roles would potentially create a conflict of interest.
