“I worked with Douglas Waller for over two years in Afghanistan, in some of the worst conditions imaginable. He was consistently the best performing, most dependable person in our department. His IT skills coupled with his can-do attitude made him the go-to person in our department for issues with computers, the network, database issues, and his knowledge of policy and procedures made him invaluable in making decision that followed our directives. He used his downtime to keep up to date on new software and database management systems, and also kept striving to complete certifications related to our assignments. His proactive approach kept our department effective and efficient while the scope of our operations were ever changing and growing. Because he wants to deliver his best he exudes professional excellence wherever he works and provides a positive example for his co-workers. Because of his positive influence Doug and I have developed a friendship that has lasted beyond the office. It would be a pleasure to work with him again.”

You're drowning in surplus spare parts for computer repair. How do you avoid unnecessary inventory costs?
Using all of these to manage inventory to control cost is recommended. Inventory is a cost of doing business whether it's office supplies or regular consumables. Knowing what you actually need when you need it rather than ad-hoc ordering and warehousing costs a lot less in usable space.

What are the best ways to maintain computer health?
Two things: Keep your software up to date with the latest security patches. Keeping software and firmware up to date reduces the possibility of zero day exploits and older vulnerabilities. Don't download attachments or click on messages that you don't recognize or that have noticeable errors. Phishing or Vishing messages are one of the primary vectors for malware. These messages can contain links that take you to websites that can download viruses.
