PURPOSE: Protect and support a humanity increasingly dependent on computers by creating a Body of Knowledge for professional and effective computer systems administration.
Problem Statement
Humanity is increasingly dependent on computers. More and more computer systems are deployed; the number of professional sysadmins is not growing equally fast and there is a shortage.
Modern policy-based configuration management tools drastically change the sysadmin to computer ratio, enabling a single sysadmin to handle thousands of computers.
Sadly, most sysadmins in the field are not familiar with these tools, or are just starting to learn about them. Tell your coworkers about configuration management!
Bottom line: the computer technology explosion is such that we need more and better sysadmins to keep humanity's computer systems online and the economies flowing.
Solution
Let's list what a sysadmin should know and be able to do.
We could then use this list to:
Train new sysadmins, and
Verify knowledge and skills of existing sysadmins, and close any gaps.
Formal definition and acceptance of this list, ideally done under the auspices of professional association and with academia involved, would establish our Body of Knowledge.
What is a Body of Knowledge?
Body of Knowledge (BOK or BoK) is a term used to represent the complete set of concepts, terms and activities that make up a professional domain, as defined by the relevant professional association.
While the term body of knowledge is also used to describe the document that defines that knowledge - the body of knowledge itself is more than simply a collection of terms; a professional reading list; a library; a website or a collection of websites; a description of professional functions; or even a collection of information. It is the accepted ontology for a specific domain.
What is "ontology"? Wikipedia gives us this:
Ontology deals with questions concerning what entities exist or can be said to exist, and how such entities can be grouped, related within a hierarchy, and subdivided according to similarities and differences.
I found a better definition in a recent paper What's Wrong with Knowledge Management? And the Emergence of Ontology by Mark Burgess.
Technically, an ontology is defined as "a set of specialized concepts within a domain" (from the Greek logos (talk about) and ontos (that which exists)). It is the term used for describing domain knowledge.
A BOK could serve as a foundation for a common cirriculum. A BOK should be useful to both academia and industry.
Clearly defining our Body of Knowledge is the next step in maturing systems administration, the next step on the journey to Profession.
Prior work
In 1997-1999, Geoff Halprin drafted a SA-BOK delineating Key Areas of Responsibilities of a systems administrator and providing a site assessment checklist.
In 2000, Rob Kolstad and the LISA community kicked off a sysadmin taxonomy project, an attempt to build an ontology of systems administration concepts. By 2002, progress has been made but the work was not completed.
In 2000, Mark Burgess wrote Principles of Network and System Administration, an introductory college text. The publisher's book description reads:
A single, comprehensive resource that responds to the high demand for specialists who can provide advice to users and handle day-to-day administration, maintenance, and support of computer systems and networks. Author approaches both network and system administration from the perspective of the principles that do not change on a day-to-day basis. Shows how to discover customer needs and then use that information to identify, interpret, and evaluate system and network requirements. New coverage includes Java services and IPv6.
Meanwhile, in 2001, Addison-Wesley published Tom Limoncelli's and Christine Hogan's The Practice of System and Network Administration, a comprehensive overview of the practical aspects of system administration.
In 2011, Aleksey Tsalolikhin compiled a Guide to the System Administration Body of Knowledge, a round-up of Normative Literature. Normative literature describes agreed upon norms or standards. Such literature is essential for standardizing and maturing systems administration. This compilation has grown into the SABOK Reading List and the sabok.org web site.
Current efforts
SABOK
Inspired by the Software Engineering Body of Knowledge (SWEBOK), we registered sabok.org and rounded up materials for professionalization:
Delineation of the boundaries of the field, its sub-fields, and fields adjacent to it
Description of professional functions
Code of ethics
Reading list (including literature on best practices)
Professional conferences
Academic degree programs
Industry certifications
Professional associations
Ontologies
None of the above is intended in an authoritarian fashion. It is intended as a draft we can edit and build agreement on.
The ontology needs the most work and is the hardest part of putting together a SABOK.
A large community effort is needed to create an ontology. We are working with LOPSA to formally establish a Professional Content Committee to move this forward as a community. We are also in communication with academia through the ops-education Google Group.
Making ontologies today requires knowledge of ontology tools or involvement of ontologists:
Judging both from my own personal experience and from existing research, ontologies are notoriously hard to create for a number of reasons, see Dicheva & Dichev (2005); Moench et al. (2003). They typically represent domain expertise, they need to be populated with knowledge by domain experts; however, the technologies for doing so are not user-friendly and so these trained experts need other experts (trained knowledge engineers) to make the models on their behalf - experts, requiring more experts.
-- Mark Burgess
There is an alternative to designing and managing an ontology as a tree.
In What's Wrong with Knowledge Management? And the Emergence of Ontology, Mark Burgess describes using promise theory to let ontology emerge as a network. Everyone contributes. Each contribution is labeled with provider. Others then vote / agree / disagree or add their own perspectives. From this network, basic patterns will emerge. This approach allows handling of greater degrees of complexity than a managed tree.
Ops School
An important related effort is Ops School. In June 2012, Avleen Vig et al. started Ops School to create complete curriculum materials for training Ops Engineers.
