DRIVE BUSINESS GROWTH WITH AGILE PROCESSES THROUGH DEVOPS FOR SAP - Pravas Ranjan Rout Executive summary With the launch of SAP S/4 HANA across the globe, there is a higher risk for release defects and increased cost when migrating from legacy processes. To meet the need for robust and agile process innovation without business disruption, Infosys has designed a DevOps implementation methodology that reduces cycle time, accelerates time-to-market and lowers TCO. This paper explains the key elements in the solution approach to DevOps in SAP along with SAP tools and IPs that assure a risk-free and smooth DevOps transformation.

This creates significant challenges as In an increasingly technology-driven world, customers use several SAP products during DevOps represents a third-generation implementation and maintenance phases. process innovation framework that extends agile methodology to overcome the This new DevOps process will reduce challenges of collaboration, culture and release cycle time, number of defects automation. As technology evolves, so do during maintenance, and total cost of processes – from waterfall to agile and, ownership (TCO) while accelerating time subsequently, to DevOps. to market. To facilitate a smooth transition from waterfall to DevOps, Infosys has DevOps signifies collaboration between designed an iDEV framework that aligns development and operations teams for with the core metrics of DevOps. With a cohesive and integrated environment. this solution, organizations can accelerate While DevOps has had successful mobile execution with fewer defects in a and cloud implementations, for SAP collaborative and automated environment.

DevOps approach While most standard implementations leverage the waterfall model of ASAP framework, there is a significant move to become proactive through agile. To enable this, Infosys has leveraged a hybrid agile approach for DevOps with a roadmap for the iDEV framework.

Key elements of the DevOps approach

1. Assessment using a maturity model utomation

A detailed assessment kit assesses the current situation of process deployment. The kit ode ractice gathers and evaluates inputs from existing SAP accounts such as the level of automation, code practice, release process, infrastructure management, culture, and key performance elease indicators (KPIs) of delivery. Infrastructure

The output is a doughnut chart that is represented as pictures with a guided roadmap. ulture The roadmap highlights the priority of activities to be completed in wave-wise planning. It focuses on the important levers of industry solutions for DevOps such as continuous easurement delivery/continuous integration (CD/CI), automation, workflow, and monitoring. rocess

The assessment findings are fed into the maturity framework as shown in the illustration. Figure 1: Assessment Maturity Levers

Hybrid Agile The Hybrid DevOps model can accelerate • Focus on unit testing the journey towards DevOps by providing: While several mature accounts continue • Automation • Gap analysis as an input to product to use the waterfall methodology through • Dashboards to monitor performance backlog SAP ASAP, agile methodology is rapidly • Workflow and notifications • Shift-left approach gaining popularity. • Increased focus on review with less • Collaboration with key business users rework on a weekly basis

Advanced features can be developed using the ABAP workbench. A comprehensive definition of tooling is available within the iDEV framework with CD/CI combined.
