Software Design and Development Cycle

Multiple developers write code for different features thattogether make software

Repository is a central location where source code liesBuild process is where source code is converted to objectcode using a set of instructions

1. Collaboration

Share knowledgeCross functional teams andfeaturesPromote DevOps Culture

DevOps: Collaboration



10/29


2. Automation

Ensure processes are executed same every timeTrigger automatic feedback at critical pointsDecreases chances of human error

3. Continuous Integration

Development practicewhere developers integratecode into a sharedrepository frequentlyDeployment of activelyintegrated repository iscalled ContinuousDeployment DevOps: Continuous Integration



12/29


4. Continuous Testing

Test code in development asfeatures are being builtRun tests when build startsTest in continuous integrationpipelines

5. Continuous Monitoring

Reporting of operations to developers and testersResponse time certain callsEnd user peak timingsRequests for specific services

Case Study of companies in Sri Lanka

Research of Perera, et al [1] which evaluated usage ofDevOpsIdentified end goals for success of a software basedcompany



21/29


Methods used for Study

Listed a set of variables and their respective indicators ofsuccess in software150 organizations were each sent a questionnaire withthose metrics and their usage of DevOpsIdentify relationship between DevOps: (a) Quality, (b)Responsiveness to business needs and (c) Adaptation tonewer technologies

DevOps Correlation

The Pearson correlation coefficient measures strength of thelinear relationship between two variables.

Coeffecients in Regression Model

Regression coefficients represent the mean change in theresponse variable for one unit of change in the predictorvariable while holding other predictors in the model constant.
