I'm trying to compose a response to this, and failing everytime. I literally cannot give a tactful response here that I feel no one will not take some offense to. So maybe it's better if I share my very, very biased experience ... 1) I've worked almost entirely in environments with SLA guarantees. A violation causes 7+ figure financial losses, and possibly several terminations. 2) Even if resolution of an issue to a problem is deferred to Level 2, any imvestigation Level 1 would do would have to be non-impacting I.e., Level 1 needs to either know tools that are non-impacting, or at least know what tools not to use 3) Turnover rates at Level 1 are the highest, so I am failing Level 1 if I don't ensure they have the knowledge to prevent an SLA violation Now peopleay define "Level 1"differently. Here I am using "Level 1" to refer to sysadmin operations, and not triage from a help desk script or knowledge base. E.g., 1 - syaadmin (operations) 2 - senior sysadmin (emgineering / implementation / escalated operations) 3 - architecture (and escalatex engineering / 2x escalated operations) For those that include triage/help desk, that would add +1 to the others (level 2-4), and level 1 would be more "user" level. In fact, that's Red Hat GLS/Training (2-4 are sysadmin level) compared to LPI (1-3 are sys admin level). - bjs P.S. Most on-line tools that are non-impacting are also useful off-line too. Hence why they are taught to Level 1 sysamdins. -- -- Bryan J Smith - http://www.linkedin.com/in/bjsmith E-mail: b.j.smith at ieee.org or me at bjsmith.me
