Executive summary / tl;dr

Learn how DevOps can help ITSM to access the strategic value envelope available for the digital transformation of the enterprise. Today, ITSM has to deal with many new, disruptive things. Digital transformation should be a key asset in the transformational leadership portfolio. For the enterprise IT, DevOps can be the cross functional common language and the toolkit to make the IT part of this transformation.

What does digital transformation imply?

ITSM is a global business, ~$90bn worth.Now it is going the disruption path through digital transformation as other businesses.

Definitions*is a set of detailed practices for IT service management (ITSM) that focuses on aligning IT services with the needs of business.

* from the Wikipedia

ITIL

DevOpsAgile

is a set of values and principles for software development under which requirements and solutions evolve through the collaborative effort of self-organizing cross-functional teams

a software engineering practice that aims at unifying software development (Dev) and software operation (Ops). The main characteristic of the DevOps movement is to strongly advocate automation and monitoring at all steps

practice: the usual way of doing something principle: a comprehensive and fundamental law, doctrine, or assumption

Agile methods: best known are Scrum and Kanban

Problem: agile is very customer centric…but has no recipes how you actually do things.

“As a customer, I want to put an item to the shopping cart.”

Things have got much complexer, and many business relevant things important for operations must be considered already during development:

-Which environment is required to run this software? (or it will not run)-Which resources are required? (or not all customers will be able to access the service)-…

10

ITIL (in theory)

11

Problem 1: ITIL is able to integrate agile methods, and it does give recipes how you do things, but measured by state of the art it can be too abstract

1. „Do we have that Definitive Media Library?“

2. „Say what?!“

4. „Say what!? Nopes.“

3. „..Can we have resources for integrating Nexus, or Artifactory? Enterprise license would be awesome!“

Talking about same things.. But in different languages.

„Tech guy“

„ITSM guy“

12

Problem 2: ITIL has no SLAs foreseen for the „project time“ services!

In terms of ITIL, projects will have some costs like a couple of servers and notebooks but no access to operational resources. And costs must be reduced.

Result is that your project cannot claim priority for execution of compilation and test jobs.A nightly end-to-end job can represent daily value increment visible to the customer. But it needs resources and maintenance.

ITSM – the end to end value chain

Long cycles = Waterfall. Short cycles = agile. Even faster = DevOps.

This is not a new waterfall!This just a model for one delivery cycle-which could be an agile sprint including production rollout

DevOps Toolchain – Smart Digital Software Factory

The market for DevOps tools is rapidly growing (Forbes). Machine engineering reinvented?

Already in 2013, companiesusing DevOps reportedup to 30-fold speedupand 50% less failures.(DevOps Report 2013 by Puppet Labs)

This is possible with well integrated advanced toolsAND thanks to silos breakdown.

CODE: Free digital components for software

Most teams build, or rather glue, 90% of their software based on free open source components, counted in dozens of millions in different central repositories.Sources are available as well, mostly at GitHub.com (social network for coders, global rank Top 10)

40M+ projects (seit 2008)

BUILD: Binary repositories as component store

• These tools can scan software under development and raise security and license issues

VALIDATE: Behavior-driven development (BDD)

21

CONFIGURE: Free digital components for executable services

Software components glued together with a system configuration to services are now available as well – thanks to container technology there is an image repository as well. There are probably millions of them as well at DockerHub.com.

Due to this new dimension of reusable knowledge is a large scale disruption of how traditional operations departments have worked for years.

… Reinventing logistics?

The new stack: Artificial Intelligence

• AI, ML, data science solutions are on the market!• Also AI/machine learning solutions require special

treatment how they can be built and delivered• There are new processes like data mining and

training of neural network models• And new generations of hardware systems

What could DevOps become in 2025?

Plan: specify service requirements together with a ChatBot or get them as proposals from your enterprise AI

• Backed by trained Speech AI and the knowledge graphs of your company, and your domain, a ChatBot could help answering many questions and some day maybe help with specifying requirements.

• As data mining is an important precondition for ChatBots, some requirements could be even discovered and proposed by the AI

Discussion - how could Agile, ITIL and DevOps cross-polinate?What could be tension factors?

“Can Agile, Lean and ITIL Coexist?”A. Smith, N. Rahman (2017)International Journal of Knowledge-Based Organizations Vol 7

A simple Google search for “Agile vs. ITIL” will net over 150 thousand results and “ITIL vs. Lean” well over a half-million more. “ITIL bureaucracy” finds over 400 thousand results.
