Evolution of production and operations management essay

DevOps is a term for a group of concepts that, while not all new, have catalyzed into a movement and are rapidly spreading throughout the technical community.

Like any new and popular term, people may have confused and sometimes contradictory impressions of what it is. We have put together a comprehensive DevOps Fundamentals course for lynda.

We hope you enjoy them. The New Secret Sauce. DevOps has strong affinities with Agile and Lean approaches. The best way to define it in depth is to use a parallel method to the definition of a similarly complex term, agile development.

Agile Values — Top level philosophy, usually agreed to be embodied in the Agile Manifesto. These are the core values that inform agile. Agile Principles — Generally agreed upon strategic approaches that support these values.

The Agile Manifesto cites a dozen of these more specific principles. Agile Methods — More specific process implementations of the principles.

Agile Practices — highly specific tactical techniques that tend to be used in conjunction with agile implementations. None are required to be agile but many agile implementations have seen value from adopting them. Standups, planning poker, backlogs, CI, all the specific artifacts a developer uses to perform their work.

Agile Tools — Specific technical implementations of these practices used by teams to facilitate doing their work according to these methods. I believe the different parts of DevOps that people are talking about map directly to these same levels. DevOps Methods — Some of the methods here are the same; you can use Scrum with operations, Kanban with operations, etc.

There are some more distinct methods, like Visible Ops -style change control and using the Incident Command System for incident reponse. DevOps Practices —Specific techniques used as part of implementing the above concepts and processes.

Infrastructure Automation — create your systems, OS configs, and app deployments as code. Continuous Delivery — build, test, deploy your apps in a fast and automated manner.

Site Reliability Engineering — operate your systems; monitoring and orchestration, sure, but also designing for operability in the first place. History of DevOps The genesis of DevOps comes from an increasing need for innovation on the systems side of technology work.

Provisioning tools like Puppet and Chef had strong showings there. More people began to think about these newer concepts and wonder how they might implement them.

Gordon Banner of the UK talked about it early on with this presentation. A lot of the focus of this movement was on process and the analogies from kanban and lean manufacturing processes to IT systems administration. The concept, now that it had a name, started to be talked up more in other venues I found out about it at OpsCamp Austin including Velocity and DevOpsDays here in the US and spread quickly.

Since then it has developed further, most notably by the inclusion of Lean principles by many of the thought leaders. What is DevOps Not? That is scary to some but is part of the value of the overall collaborative approach.

And I have yet to see anyone automate themselves out of a job in high tech — as lower level concerns become more automated, technically skilled staff start solving the higher value problems up one level.

Automation is just the exercise of power, and unwise automation can do as much damage as wise automation can bring benefit. Similarly, Agile practitioners would tell you that just starting to work in iterations or adopting other specific practices without initiating meaningful collaboration is likely to not work out real well.

Though there is some of that. DevOps consists of items at all the levels I list above, and is largely useless without the tangible body of practice that has emerged around it. You might be able to figure out all those best practices yourself given the cultural direction and lots of time to experiment, but sharing information is why we have the Internet and printing press for that matter.Please complete the form below so that we can provide you with more information about UMSL.
