The document describes different levels of expertise from novice to expert. It outlines the key characteristics of each level: - Novices require strict rules and get stuck when things are unexpected. Advanced beginners can complete tasks alone but struggle with troubleshooting. - Competents have conceptual models and can troubleshoot, solving novel problems and showing initiative. Proficients see the big picture and learn from others' experiences. - Experts are primary knowledge sources, constantly improving and publishing work from intuition, easily discerning relevant details.

- 3. Novice • Wants to achieve a goal, and not particularly interested in learning. • Requires context free rules to follow. • When something unexpected happens will get stuck. Advanced Beginner • Beginning to break away from fixed rules. • Can accomplish tasks on own, but still has difficulty troubleshooting. • Wants information fast. Competent • Developed a conceptual model of task environment. Able to troubleshoot. • Beginning to solve novel problems. Seeks out and solve problems. • Shows initiative and resourcefulness. • May still have trouble determining which details to focus on when solving a problem.
- 4. Proficient • Needs the big picture. • Able to reflect on approach in order to perform better next time. • Learns from experience of others. , Applies maxims and patterns. Expert • Primary source of knowledge and information in a field. • Constantly look for better ways of doing things. • Write books and articles and does the lecture circuit. • Work from intuition. • Knows the difference between irrelevant and important details.
- 5. You want to solve a problem but are unaware that there is knowledge that would help. You have a sense that there must be something that will help, but you are unaware of where to find it. You know where it is, but you do not have access to it. You have access to it, but do not understand how to make it work. You get it to work, but find out that it is not what you thought.
- 6. 0OI • Lack of ignorance • I (probably) know something 1OI • Lack of knowledge • I don’t know something 2OI • Lack of awareness • I don’t know that I don’t know something 3OI • Lack of process • I don't know a suitably efficient way to find out I don't know that I don't know something 4OI • Meta-ignorance • I don't know about the Five Orders of Ignorance
- 7. 0OC • Unconscious incompetence • You don’t know that you can’t do it well 1OC • Conscious incompetence • You know you can’t do it well 2OC • Conscious competence • You do it well, and you think about 3OC • Unconscious competence • You do it well, without thinking about it • You’re so successful it’s automatic
- 8. OP1 • A constant numerical or text value used to identify a file format or protocol; for files, see List of file signatures OP2 • Distinctive unique values that are unlikely to be mistaken for other meanings (e.g., Globally Unique Identifiers) OP3 • Unique values with unexplained meaning or multiple occurrences which could (preferably) be replaced with named constants

- #7: From Communications of the ACM - October 2000, Volume 43, Issue 10: 0th Order Ignorance: Lack of Ignorance. I have 0OI when I (probably) know something. 1st Order Ignorance: Lack of Knowledge. I have 1OI when I don't know something. With 1OI we have the question in a well-factored form. 2nd Order Ignorance: Lack of Awareness. I have 2OI when I don't know that I don't know something. 3rd Order Ignorance: Lack of Process. I have 3OI when I don't know a suitably efficient way to find out I don't know that I don't know something. 4th Order Ignorance: Meta-ignorance. I have 4OI when I don't know about the Five Orders of Ignorance. Unit tests are a way to turn 1OI to 0OI. Common knowledge sharing is a way to turn 2OI to 1OI In 3OI you know that you can’t get to 1OI. You need to solve it in the organization by finding ways to share knowledge / ignorance.
- #8: UnconsciousIncompetence = you don't know that you can't do it well. ConsciousIncompetence? = you know you can't do it well. ConsciousCompetence? = you do it well, and you think about the work as you do it. UnconsciousCompetence = you're so successful it's "automatic" -- you do it well, without thinking about it. and we add:
- #17: An approximate calculation or judgment of the value, number, quantity, or extent of something.
