Why Manufacturing Digital Transformation Should Be Led By CIOs

Manufacturing sits at the intersection of IT, operational technology (OT), and the business. Leading digital transformation efforts positions CIOs to align existing IT assets, OT infrastructure, shop floor processes, and enterprise strategy to deliver bottom-line results. Think improved throughput, lower downtime, asset utilization, and total cost of ownership. Digital transformation initiatives focusing on data modernization, Industrial IoT (IIoT), AI-powered analytics, and cloud empower smart factory solutions that improve operations at scale. With customers, Hexaware positions AI first and focuses on how to modernize existing legacy systems to surface real-time shop floor insights.

5-Phase Manufacturing Digital Transformation Roadmap Overview 

This guide breaks down a large transformation effort into five achievable phases that CIOs can use to plan out investments, governance changes, and operational capabilities.

• Phase 1: Current state assessment 
• Phase 2: Define vision and use cases 
• Phase 3: Foundation building – Data, connectivity, modernization 
• Phase 4: Proof of concept and piloting use cases 
• Phase 5: Scaling and governing for continuous value 

Each phase focuses on major deliverables, key performance indicators (KPIs), stakeholder ownership, and typical timelines. Below we dig into each phase with practical recommendations and technologies you should consider.

Manufacturing Digital Transformation Roadmap

Phase 1 – Current State Assessment 

Objective: Define the current state of IT assets, OT infrastructure, and process DNA.

Activities 

• Inventory current assets: PLCs, SCADA, MES, enterprise resource planning (ERP), sensors, robots, PLC firmware versions, network topology, etc.
• Map IT and OT data flows/ownership. 
• Perform current state capability check: connectivity, latency, security posture, data quality, historian coverage, existing analytics.
• Determine biggest business pain points to target with use cases: frequent downtime events, yield misses, excess inventory, quality escapes, manual workarounds.
• Establish financial baseline: how much money is lost each year due to downtime, scrap, expedited logistics charges, manual errors?

Key Deliverables 

• Complete architecture diagram and asset inventory of current state.
• Value stream mapping data maturity assessment. 
• Identification of high pain point business processes. 

Phase 2 – Define Vision and Prioritize Use Cases

Objective: Establish transformation vision, value themes, and prioritize target use cases.

Steps 

Align on vision with key business stakeholders. Interview plant managers, supply chain leaders, quality leaders, and finance to understand business objectives the transformation effort will support.

• Define value themes such as maximize uptime, right size inventory, quality by design, flexible/agile manufacturing methods, energy reduction.
• Create/use a simple value versus implementation effort matrix to prioritize use cases. Focus early efforts on proven quick wins that have tangible ROI and learning value.

Examples of High Value Manufacturing Use Cases

• Predictive maintenance on critical assets. 
• Production scheduling based on real time constraints and downstream demand signals.
• Predictive quality analytics for defect detection. 
• Digital twins to simulate process changes. 

Lean methodologies like JIT digitalization to optimize inventory levels and replenishment. Read Hexaware’s research and whitepaper on JIT digitalization.

Output 

Prioritized backlog of use cases, including business value, rough implementation effort, and minimal data requirements.

Phase 3 – Build the Foundation: Focus on Data, Connectivity, and Modernization 

Objective: Architect a scalable data and connectivity backbone that enables analytics and automation at speed and scale.

Focus Areas 

• Edge connectivity and IIoT gateways: Ensure secure, low-latency data ingestion from PLCs, sensors, machine controllers, etc.
• Legacy MES and ERP integration modernization: Reduce latency between shop floor data and enterprise systems by replacing or augmenting existing legacy connectors and data protocols. Hexaware has mentioned legacy modernization as a critical enabler for unlocking real-time insights.
• Central data lake/data fabric: Consolidate shop floor and enterprise data into a central repository with governed data schemas enabling analytics and model consumption.
• Cloud/hybrid platform: Leverage cloud for analytics/model training workloads while maintaining low-latency control loops on-premises or at the edge.
• Security and identity: Define network segmentation between IT and OT networks, implement strong authentication, and encrypt firmware updates.

Recommended Implementation Patterns 

Start with a microservices-based, API first integration factory to speed up downstream integrations. Hexaware provides concepts such as APIfication and a unified API factory to help organizations integrate systems and reuse common APIs.

• Deploy containerized analytics models on the edge for those use cases that require low latency.
• Standardize device management/telemetry for connected devices to speed up onboarding.
• Governance considerations 
• Define data owners and data stewards. 
• Define security baseline and OT incident response/playbook. 

Create Center of Excellence (COE) for data and manufacturing specific models. Build this COE to codify repeatable practices and enable reuse. Hexaware advocates for COEs as well as factory patterns for driving automation and operationalization.

Phase 4 – Proof of Concept (PoC) and Piloting Smart Factory Use Cases

Objective: Focus on executing one or more PoCs that result in measurable business outcomes.

Pilot Approach 

• Build small, achievable pilots with well-defined success metrics. This includes establishing an MVP scope to validate assumptions.
• Embrace a build-measure-learn mindset. Keep pilots small and focused on single production lines or asset families.
• Ensure pilots have cross-functional ownership from plant engineering, IT, data scientists, and operations.

Examples of Common Manufacturing Pilots 

• Predictive maintenance pilot on one machine to reduce unplanned downtime by X%.
• Anomaly detection for quality on a production line to reduce scrap by Y%.
• Dynamic production scheduling pilot that combines real-time machine availabilities with order criticality to drive higher throughput.

Industrialization Strategy

• Stabilize pilot MVPs into production-ready offerings. Monitor alerts must be production-ready along with the operations playbook.
• Codify standard integration patterns/APIs so MVP solutions can be replicated across multiple factories/plants. Hexaware offers Unified API Factory methods to drastically reduce integration efforts.

Operationalizing the Smart Factory Solution 

• Train plant teams on support responsibilities. Dashboards must be actionable and role-based. Think customized dashboards for machine operators versus production schedulers.
• New operating roles will need to be introduced on the plant floor, such as data stewards, analytics operators, and digital maintenance engineers.
• Define process playbooks that standardize how anomalies drive work orders, parts replenishment, and supplier quality notifications.

KPI Examples to Track During Industrialization/Pilot to Production Handoffs

• Percentage of pilots pushed to production. 
• Reduction in unplanned downtime. 
• Increase in first pass yield. 
• Average time to detect quality incidents. 

Phase 5 – Scale and Govern for Continuous Value

Objective: Move from siloed digital projects to an optimized smart factory operating model that delivers continuous and exponential value.

Scaling Strategy 

• Plant software/template approach: build a repeatable plant blueprint that includes architecture, common APIs, data models, process playbooks, and governances. This blueprint can then be applied to other plants.
• Focus on impact when scaling: not all use cases will have the same ROI. Scale highest value applications first. 
• Phase manufacturing rollout: avoid trying to tackle too many sites at once. Establish gates to validate readiness and automate repetitive tasks during rollout where possible.

Governance & Operational Model 

• Define a digital manufacturing council with representation from IT, OT, operations, supply chain, and finance.
• Transition from project funding to product funding. Digital capabilities should be considered products with budgets to support ongoing enhancements.
• Implement an enterprise performance dashboard that links plant-level KPIs to finance and business objectives.

Measure Continuous Value 

• Every project should be mapped to an outcomes catalogue. Hexaware recommends linking automation, cloud, and CX pillars to measure overall value.
• Automation enables repeatable processes. Measure how many man hours have been saved by automation.
• Run quarterly value reviews to assess progress and optimize the transformation roadmap.

Technology Building Blocks for Manufacturing Digital Transformation 

There are several key technologies and platforms CIOs should evaluate to realize a manufacturing digital transformation program. Below, we list key technology building blocks as well as architectural patterns to consider.

Key Technology Building Blocks 

• IIoT platform for device telemetry and edge compute nodes.
• Predictive maintenance and mlOps platform for building and deploying models.
• Digital twins platform to manage process simulations. 
• MES/MOM system that integrates smoothly with ERP via APIs.
• RPA tools for process automation in back office and manual tasks.
• Low code development platforms for creating custom dashboards/widgets.

Recommended Architectural Patterns 

• Adopt an API first integration strategy. Decomposing monolithic applications into APIs will enable reuse and scale future efforts.
• Hybrid cloud architecture. Maintain low latency control loops on premise or edge nodes while leveraging cloud for analytics and model training.
• Event-driven architecture for real-time alerting and automation.
• Data mesh/data lake architecture with clear data stewardship.
• Partner/Vendor evaluation considerations 

CIOs should evaluate partners based on manufacturing domain expertise, OT integration experience, and cloud scalability.

People, Process, and Culture: The Change Management Agenda

Digital transformation is not possible without changing how employees work and embracing new technologies. Below, we provide recommendations for CIOs on how they can build a change management plan that focuses on culture, processes, and enabling technologies.

People Change Agenda 

• Upskill existing workforce to include data literacy, ML model interpretation, and basic digital operations understanding.
• Build new cross-functional teams combining traditional plant engineers with data scientists, data integrators, and IT operations.

Process 

• Redesign business processes to account for digital signals from ML models flowing into work orders, planned maintenance activities, supplier quality alerts, etc.
• Create a culture of innovation and continuous learning by defining short feedback loops. Learn from pilots and apply to future transformation efforts.

Adoption 

• Create standardized learning loops from pilots to build out training curriculum.
• Bonus team members on measured improvements to KPIs instead of just successful project deliveries.
• Ensure all created dashboards are linked to daily work and are actionable by the intended audience. Executive dashboards should focus on overall plant health and drive proper interventions.
• Measuring return on investment (ROI) for manufacturing digital transformation

As CIOs embark on this journey, it is critical to measure success and determine ROI. We provide a high-level overview of how we recommend building a business case to fund digital initiatives.

Modeling Business Value 

Calculate use case-specific ROI: how does predictive maintenance save money on downtime? What about energy savings from optimizing energy usage during downtime? How much does reducing scrap through quality analytics improve margins? What about reducing inventory levels through JIT digitalization? How much faster can we launch new products with digital twins?

Don’t forget to capture soft benefits: improved customer satisfaction, reduced NPI cycles, higher employee retention, etc.

Build a 3-year net present value (NPV) model that captures initial modernization costs as well as ongoing run costs. Keep in mind that data ingestion costs will decrease as more assets are connected.

Example Business Value Drivers 

• Predictive maintenance that detects unplanned downtime could save millions, depending on asset criticality.
• Early defect detection through quality analytics can dramatically improve bottom line profits.
• Lean operations through JIT can dramatically reduce working capital requirements.

TCO And Cost of Change Considerations 

• Remember to account for TCO of cloud hosting, edge devices, connectivity, support personnel, training, and security.
• Factor in data governance/data engineering costs as well as ongoing model retraining costs.
• Retiring legacy systems? Factor that into overall savings. 

Managing Risks During Digital Transformation 

Since transformations are unique to each organization, risks will vary based on use cases. However, we’ve seen common pitfalls from prior implementations that you can learn from.

Common Risks 

• Transformation projects that fail to integrate into the larger ecosystem. Lost opportunity and reuse. 
• Underestimating data preparation and integration complexity. 
• Projects that focus on using new technology shiny objects rather than specific business goals.
• Poor OT security design that leads to longer downtimes.

Risk Mitigation Strategies 

• Invest time in creating an integration factory and standardizing common APIs to maximize reuse.
• Invest in data preparation and do not start model building until data quality is assured.
• Emphasize measuring success and defining KPIs on pilot projects. Combine with clear ownership of pilots. 
• Implement security best practices focused on OT environments. Network segregation is often the first step.
