"HOW WILL WE IMPLEMENT

DEVOPS IN OUR

ORGANIZATION?"- unnamed C-level manager


BY DEVELOPING CULTURE,

REMOVING BOUNDARIES AND

IMPLEMENTING PROVEN

CONCEPTS.


"BUT HOW DO WE MEASURE THIS

ON AN ORGANIZATIONAL SCALE?"- unnamed C-level manager

SOFTWARE DELIVERY

PERFORMANCEas the key performance indicator contains

delivery lead time to change

deployment frequency

mean time to restore

change fail rate


HIGH PERFORMING DEVOPS

ADOPTERSdeploy 46x more frequently

lead time from commit to deploy is 440x faster

mean time of recovery from downtime is 170x faster

change failure rate is 5x lower

High performers vs. low performers Source: Accelerate: State of DevOps 2018

IMPROVING SOFTWARE DELIVERY

PERFORMANCE


CAPABILITIES, NOT MATURITY.Maturity models describe a static path & finished state.

Which doesn't fit to DevOps. DevOps evolves every single day.


5 CATEGORIES OF CAPABILITIES

CONTINUOUS DELIVERY

LEAN MANAGEMENT & MONITORING

CULTURE


CONTINUOUS DELIVERY

Continuous Delivery

VERSION CONTROL EVERYTHINGCode of your application, configuration of your application, script for

automation, systems configuration & environment configuration.


Continuous Delivery

FULLY AUTOMATED DEPLOYMENT

PROCESSDeployments without manual interference.


Continuous Delivery

USE CONTINUOUS INTEGRATIONRegular check-ins to code repository and automated tests with fast

feedback.


Continuous Delivery

TRUNK-BASED DEVELOPMENTShort-living feature branches with a simple branching concept, no code

freeze-periods necessary through feature toggles.


Continuous Delivery

TEST AUTOMATIONDevelopers take responsibility for a reliable and automated test suite, testing

for real flaws.


Continuous Delivery

TEST DATA MANAGEMENTMinimal set of test data to drive a test suite, not limited by the number of

test executions.


Continuous Delivery

DEVSECOPS ‐ INTEGRATE SECURITY IN

SOFTWARE DEVELOPMENT LIFECYCLEIntegrate security in design & testing phase, conduct early security review,

enhance security know-how within your teams, use standard libraries & write

test, test, test.


Continuous Delivery

IMPLEMENT CONTINUOUS DELIVERYPrioritize on keeping software in a deployable state, implement fast

feedback on quality & deployability visible to everyone, systems are

deployable on demand, any time.


ARCHITECTURE

Architecture

LOOSELY COUPLED ARCHITECTURESReduce orchestration necessity for test and deployment, work independent

of other system providers.


Architecture

EMPOWERED TEAMSTeams should choose their own weapons, like tools and technologies, no

one knows better than the team how they can be effective.


PRODUCT & PROCESS


Product & Process

WORK IN SMALL BATCHESTeams should slice features & products into minimal batches, to be released

in rapid cycles.


Product & Process

COLLECT & IMPLEMENT CUSTOMER

FEEDBACKMaking customers satisfied drives team motivation.


Product & Process

VISUALIZE FLOW OF WORKTeams should understand the flow of work from business to the customer,

enabling for example better technical decisions.


Product & Process

ENCOURAGE AND EMPOWER TEAM

EXPERIMENTATIONEnable the teams to try out new things, create and update specifications

during the development process without external approval, encouraging

innovation and new value added.


LEAN MANAGEMENT &

MONITORING


Lean Management & Monitoring

LIGHTWEIGHT CHANGE APPROVAL

PROCESSSoftware delivery performance is highly impacted by a lightweight change

process, like peer review or pair programming, without an external change

advisory board.



MONITOR ACROSS APPLICATIONS &

INFRASTRUCTURE TO ENABLE INFORMED

BUSINESS DECISIONS

Take action & informed decisions based on data from applications and

infrastructure, reduce wrong people being paged (on-call-duty).



PROACTIVELY CHECK SYSTEM HEALTHUse rate-of-change warnings and thresholds to monitor systems health,

preventively detect issues and mitigate early.



ESTABLISH WORK-IN-PROGRESS

LIMITSWork-in-progress limits manage the flow of work to increase actual

throughput, automatically.



VISUALIZE WORK TO ALL TEAM

MEMBERS TO MONITOR QUALITY AND

COMMUNICATIONCreate dashboards to monitor quality, work in progress and status to keep all

informed.


CULTURE


Culture

SUPPORT A PERFORMANCE ORIENTED

CULTURESuch a culture is reflected through a highly transparent information flow,

trust, high cooperation, bridging between teams & conscious inquiry.

Culture

ENCOURAGE AND SUPPORT LEARNINGLearning is considered as crucial part of continuous progress & not just an

one time investment.


Culture

FACILITATE COLLABORATION AMONG

TEAMSTake down tradional silos. Everywhere.


Culture

PROVIDE RESOURCES AND TOOLS

THAT MAKE WORK MEANINGFULMeaningful work is one key factor for job satisfaction. Provide tools and

resources that are needed to do the job the right way. That can be context,

empowerment, new skills, or just hardware.


Culture

SUPPORT OR EMBODY

TRANSFORMATIONAL LEADERSHIPThe technical and process work, which is essential to DevOps is supported,

and strengthened by transformational leadership, which covers vision,

intellectual stimulation, inspirational communication, supportive leadership

& personal recognition.


DEVOPS IS NOT LIMITED TO

SOFTWARE DEVELOPMENT

EVERYONE NEEDS TO BE INVOLVED.
