This document discusses Centric Consulting's approach to helping clients implement a "bimodal" IT model that supports both predictable "Mode 1" systems and more innovative "Mode 2" systems. It summarizes Centric's view that balancing speed and stability requires abstracting dependencies, aligning teams, embracing automation, and focusing on culture. Case studies demonstrate how Centric has successfully delivered Mode 2 applications while integrating with clients' Mode 1 operations through practices like microservices, cloud deployment, and iterative development.

- 2. CONTENTS • What is Bimodal? • Challenges moving to Bimodal • Centric’s Point of View on how to make Bimodal IT work • Centric Services • Centric’s Key Differentiators The presentation addresses the following topics. 2
- 3. WHAT IS BIMODAL? Gartner introduced prescriptive enterprise IT organizational model “Bimodal” in 2014. 3 Bimodal is the practice of managing two separate but coherent styles of work – one focused on predictability and the other on exploration. Mode 1 Legacy Evolution Mode 2 New and Innovative • More predictable and well understood • Focused on exploiting what is known and • Renovating the legacy environment • Exploratory • Experimenting to solve new problems • Optimized for areas of uncertainty • Begins with hypothesis - tested and adapted • Developed in short iterations • Minimum Viable Product (MVP) approach Gartner
- 4. TRENDS DRIVING BIMODAL Digital business innovation is creating disruption - impacting people and technology. 4 Digital Experience and Engagement – new ways to interact using technology Business Innovation – Disruptors: Google, Apple, Amazon, Facebook, Uber, etc. Ripple Effect – Expanding digital capabilities increases importance on Mode 1
- 5. CHALLENGES BEING BIMODAL There is tension between Mode 1 legacy and Mode 2 innovation. 5 “Tension rises when dev teams operate outside the guardrails.” Tension Mode 1 Mode 2 Outsourcing Contracts On Premise Infrastructure SDLC ProcessIT Staffing & Skill Mix Tightly Coupled Architecture Data Security Cloud First Mobile First Customer Facing Innovation Legacy New and Innovative Guardrails – the predictable things ordinarily done… known as “inertia.” Agile CI/CD Automation Forces Creating Tension Release Schedules
- 6. OBSTACLES WE ARE SEEING Transitioning to Bimodal has many challenges – from technology to organization. 6 Turf Wars DevOps, Infra, Arch. Decision Conflicts Culture “Us vs Them” Re-work Fear Can’t fail –wait so don’t create rework Upfront Design All Requirements Before Dev Starts Architecture Tight Coupling Creates Dependency
- 7. SPEED WITHOUT DISRUPTION Overcoming obstacles in Mode 2 requires balancing speed without disrupting Mode 1. 7 Speed Disruption Rapid Startup Embrace DevOps & Automation Manage Priorities Against Backlog Flex Resources to Balance Supply/Demand Digital Innovation w/ Software Faster Delivery Lower Cost Remove Tight Dependencies Productive Teams Make it Easy to change Self Documentation Goal: Don’t make it take longer than it needs to take. Mode 1 + 2
- 8. CULTURE MATTERS The organizational, culture and people impacts in Bimodal are paramount. 8 Mode 1 + Mode 2 Teams Go through High Performing Team Stages Form Storm Norm Time Performance • Clear vision and purpose • Mutual goals - 1+1=3 • Org alignment on technology • DevOps and Legacy coexist • Agile skills - Mode 1 and 2 • Test and learn mindset • Culture norm - Failure is ok • New thinking – its ok to change • Knowing enough to get started • Career paths – Mode 1 and 2 Cultural Factors in Bimodal
- 9. MAKING MODE 2 WORK The new norm is iterative test and learn application development. 9 Goal: Shorten Feedback Loops by applying know patterns and practices. Write failing Unit Test Make Unit Test Pass Refactor Repeat until acceptance test passes Write failing Acceptance Test Verify Feature Complete Repeat until feature is complete Acceptance Test Driven Development Discuss Feature and Acceptance Criteria Backlog Repeat until Backlog is empty Promote Code
- 10. SECRET SAUCE Abstraction and alignment with Dev and Ops – such that Modes 1 and 2 applications have common “shared” dependencies governed by contracts and known practices. 10 Mode 1 Mode 2 Tight Coupling Implementing Agile without Abstraction “Mode 2 can only go as fast as Mode 1”
- 11. SECRET SAUCE Abstraction and alignment with Dev and Ops – such that Modes 1 and 2 applications have common “shared” dependencies governed by contracts and known practices. 11 Mode 1 Mode 2 XTight Coupling Infrastructure • Shared File System • API Gateway • Asynchronous Queuing • ESB Contracts Examples Shared Dependencies governed by contracts Key: Address ownership and accountability in IT organization
- 12. INGREDIENTS Here is how Centric makes Mode 2 work alongside Client’s Mode 1 teams. 12 Centric Scrum Team Team Tools – embrace automation Space Collaboration • Preserve Core Team (SM, BA, etc.) • Team trust and know each other • Team Profiles – Know standard technologies, Open Source, and are curious learners • Don’t use every tool – menu choices • Team Boards (Jira, Pivotal, Trello, TFS) • Source Control (GitHub mainly, TFS) • CI/CD (TeamCity, TFS, Octopus) • Testing (Cucumber, Selenium Web Driver) • Coding (node.js, JavaScript, Java, .Net) • Cloud (AWS, Azure, Heroku) • Everything needed - nothing not needed • Remove distractions - No bureaucracy • Care and Feeding (Snacks/Drinks) • Pleasant environment to work • Balance public and private space • Screen sharing, Video Conferencing • Team Collaboration - Slack • Transparency – Digital Team Boards • Agile – build things that are easy to change • Shorten feedback loop – embed client • Show and Tells – what we have done • Set priorities regularly • Allow client to change mind
- 13. Centric Services Centric helps client operate Bimodal with three service offerings 13 Readiness Assessment and Roadmap Mode 2 Software Development Application Support • Educate clients on bimodal – trends, hurdles, etc. • Assess organizational readiness & gaps • Create Roadmap and Plan for Bimodal journey • Form Team - Columbus Dev Studio • Align and Integrate with Mode 1 Teams • Execute Agile software delivery in Mode 2 • Transition Mode 2 App Delivery to Support Model • Leverage Centric India App Support Organization • Align SLAs with Client Mode 1
- 14. BIMODAL PARTNERSHIP • True Partnership (between Centric/Client and between Mode 1/2 teams) • Open and frequent dialogue • Candid expression of how things are working • Honesty • Leadership - client organizations committed to making bimodal work • Culture Shift - Know and understand we may fail, and if we do, learn and make it better • Apply Bimodal Success Factors • Shared dependencies – not tight coupling • Defined contracts and owners • Alignment on technology stack/menu and IT direction • Defined processes - Agile Development, DevOps, Team Collaboration, Backlog, etc. • Agreed decision making and escalation process These are “Must Haves” for a successful Centric and Client Bimodal partnership. 14
- 15. DIFFERENTIATORS • We are humble. “It’s not our way or the highway approach” • We work to integrate seamlessly within the client’s culture - it’s critical to success! • Decouple Mode 2 application development from Mode 1 architecture dependencies • Prepare to bring back application back into the Enterprise – right from the start • Offer to run and support application after deployment • Work as one – our goal is to ensure that the business needs are met… while ensuring both Mode 1 and Mode 2 team members feel they are contributing There are six key factors that make Centric a preferred Mode 2 Bimodal partner 15
- 16. CASE STUDY #1 Learning: Alignment between Agile teams and Client IT Dev and Ops teams is key. 16 Situation: US Healthcare Solutions provider needed a customer portal where they could access account information, view documents and manage their account user preferences. Challenges: Client was new to Agile software delivery and did not have a mature IT team. What We Did: What We Learned: • Built app in Java and JavaScript • Consumed APIs to access patient info • Leveraged productivity tools: Jira, Confluence, GitHub, Selenium, Maven • Deployed in Cloud – AWS • Extended tech stack for new CSR App • Now rewriting in Angular2 • Team dynamics key – know each other • Anchor new teams w/ proven talent • Spawn new teams from existing teams • API versioning – w/o introducing breaking changes Key Takeaway: Need disciplined process to govern contracts – knowing when to change, how to change, and by whom.
- 17. CASE STUDY #2 Learning: Abstraction of applications from infrastructure is key. 17 Situation: Global health care services company and leading American health care retailer needed a system to reconcile generic drug pricing against contractual agreements. Challenges: new joint company, No IT, very large data sets (>M trxs/day), AWS deployment, High $ value/high risks. What We Did: What We Learned: • Built application in Java • Deployed in AWS • Extracted/imported from multiple db’s • Performed daily reconciliations • Created reporting UI • Built analytic views – evaluated bids • Provided comparative COGS • Know team, trust team and their skills • Leadership key – both SM and BA • Poly-skilled team: i.e. SM with BA skills • Insulate team from bureaucracy • Analytics services in Azure (custom) • Leverage Open Source tools • Efficient processing: asynchronous communication, micro services, etc. Key Takeaway: Well defined contracts (applications to infrastructure) enable teams to move at right speed.
