Information Technology
IT as part of the operating model. 40 parts in six blocks, from digital foundations and network economics to architecture, platforms, AI governance and the digital operating model.
Technology does not improve an organization simply because it is installed. This series looks at information technology from the operations side: which decisions it improves, which costs it changes and which governance it needs. Every part closes with an executive decision lens and one Operations Insider takeaway.
Block 1Digital Foundations
Part 1 of 40Information Technology as an Operating SystemWhy IT is no longer a support function but part of how modern organizations sense, decide, coordinate and execute.Part 2 of 40The Economics of Computing: Moore’s Law Beyond the Transistor CountMoore’s Law still matters as an economic force, but modern computing gains increasingly come from parallelism, accelerators, chiplets, packaging and software as well as transistor scaling.Part 3 of 40From 3G and LTE to 5G-Advanced: Connectivity as Business InfrastructureThe old mobile-network evolution story becomes a modern lesson in connectivity as infrastructure for mobile work, industrial systems and edge computing.Part 4 of 40Why Bandwidth Changes Business ModelsCheap, abundant bandwidth does more than improve speed: it changes what can be centralized, distributed, streamed, monitored and automated.Part 10 of 40Cloud Native, APIs and the Modern IT StackModern IT increasingly relies on cloud services, containers, APIs, automation and observable distributed systems rather than isolated monolithic applications.
Block 2Networks, Adoption and Disruption
Part 5 of 40Network Effects Explained: Sarnoff, Metcalfe and ReedThree classic network-value models explain why audiences, connections and groups create different scaling dynamics, and why platform growth can become nonlinear.Part 6 of 40Diffusion of Innovation: Why Technologies Spread at Different SpeedsTechnology adoption follows recognizable patterns because customer value, compatibility, complexity, trialability and social proof differ across segments.Part 7 of 40Crossing the Chasm: From Visionaries to PragmatistsThe gap between enthusiastic early users and pragmatic mainstream customers is a product, proof, support and market-development problem, not just a marketing problem.Part 8 of 40The Law of Disruption: Why Organizations Lag Behind TechnologyTechnology can improve exponentially while organizations, regulation and human behavior change incrementally, creating a widening capability and governance gap.Part 9 of 40The Digital Divide Is Now a Capability DivideAccess remains important, but competitive advantage increasingly depends on digital literacy, data fluency, AI literacy and the ability to learn continuously.
Block 3Economics and Governance
Part 11 of 40Information Economics: Why Information Costs MatterMarkets and organizations do not operate with perfect information; the cost of finding, interpreting and validating information shapes real economic behavior.Part 12 of 40Transaction Cost Economics: Why Firms ExistCoase’s central question, why use a firm instead of the market, provides a powerful lens for understanding outsourcing, platforms, ecosystems and digital organization design.Part 13 of 40Search, Bargaining and Monitoring Costs in Digital MarketsDigital tools reduce many transaction costs, but they do not eliminate the need to search, negotiate, verify, govern and monitor exchanges.Part 14 of 40Market, Hierarchy or Hybrid? Choosing the Right Governance ModelOrganizations coordinate work through markets, hierarchies and hybrids; the optimal choice depends on uncertainty, specificity, frequency and the cost of coordination.Part 15 of 40Make-or-Buy in the Digital EnterpriseMake-or-buy decisions now extend beyond physical production to software, data, cloud, AI models, cybersecurity and specialist digital capabilities.Part 16 of 40Asset Specificity, Uncertainty and the Hold-Up ProblemThe more specific an investment is to one relationship, the greater the dependence, and the stronger the need for contracts, governance or ownership safeguards.Part 17 of 40Principal-Agent Problems in Digital OrganizationsWhen decision makers and those who execute work have different information and incentives, monitoring and incentive design become core management problems.Part 18 of 40Adverse Selection and Moral Hazard: Two Forms of Information AsymmetryHidden characteristics distort selection before a transaction; hidden actions distort behavior after it. Both create operational and market inefficiency.Part 19 of 40Signaling, Screening and Trust in Digital MarketsMarkets develop signals, screening mechanisms, ratings, certifications and guarantees to reduce information asymmetry and make transactions possible.Part 20 of 40How Information Technology Shrinks Transaction Costs and Changes Firm BoundariesAs information and coordination costs fall, organizations can outsource, partner, decentralize and scale differently, but new integration and governance costs appear.Part 21 of 40Networked Organizations, Ecosystems and the Diminishing FirmDigital coordination allows firms to become more networked, modular and ecosystem-based, but boundary choices still depend on control, capability and risk.
Block 4Strategy and Architecture
Part 22 of 40Porter’s Five Forces in Digital MarketsDigital technology reshapes barriers to entry, supplier power, buyer power, substitutes and rivalry, but it does not make industry structure irrelevant.Part 23 of 40From Value Chain to Value Network: How IT Reconfigures Competitive AdvantageInformation technology connects primary and support activities, compresses handoffs and turns linear value chains into increasingly networked systems.Part 24 of 40Enterprise Architecture: Linking Strategy, Processes, Data and SystemsEnterprise architecture creates a coherent view of how business capabilities, processes, information, applications and technology fit together.Part 25 of 40APIs, Integration and the Composable EnterpriseModern digital operating models depend on well-governed interfaces that let systems, partners and products exchange data and capabilities without recreating point-to-point complexity.
Block 5Markets, Customers and Platforms
Part 26 of 40E-Commerce vs E-Business: The Operating Model Behind Digital RevenueE-commerce is the transaction layer; e-business is the wider operating system that connects customers, suppliers, fulfillment, finance and service.Part 27 of 40B2B Digital Commerce, E-Procurement and MarketplacesB2B digital commerce reduces friction in sourcing and transactions, but integration, governance, data quality and supplier adoption determine the real value.Part 28 of 40Platform Economics: Marketplaces, Ecosystems and ReintermediationDigital markets often remove traditional intermediaries only to create new ones whose value lies in discovery, trust, standards, payments, logistics and network effects.Part 29 of 40CRM to Revenue Operations: Managing the Customer System End to EndCRM is more than a sales database: it coordinates marketing, sales, service, customer data and lifecycle decisions around a shared view of the customer.Part 30 of 40Customer Engagement, Personalization and Omnichannel OperationsCustomer engagement becomes operational when insight, content, offers, channels, service and feedback work as one repeatable system.
Block 6Digital Operations, AI and Resilience
Part 31 of 40Data as an Operating Asset: Governance, Interoperability and the EU Data ActData creates operational value only when ownership, access, quality, interoperability and usage rights are governed across systems and organizational boundaries.Part 32 of 40Digital Supply Chains: ERP, SCM, EDI, IoT and End-to-End VisibilityDigital supply chains combine planning, transactions, material flow and real-time signals so decisions can be made across organizational boundaries rather than inside isolated functions.Part 33 of 40The Bullwhip Effect: Why Digital Visibility Does Not Automatically Stabilize Supply ChainsDemand distortion can amplify upstream even in connected supply chains; technology helps only when incentives, planning logic, lead times and data sharing also improve.Part 34 of 40Mass Customization and Configure-to-Order in the Digital EnterpriseDigital product models, modular architecture and integrated order-to-production processes make variety scalable when complexity is designed rather than merely accepted.Part 35 of 40AI and Generative AI in Enterprise OperationsAI changes information work by turning prediction, classification, generation and decision support into scalable capabilities embedded in operational workflows.Part 36 of 40Cybersecurity as an Operating System: From Controls to ResilienceCybersecurity is now an enterprise operating discipline that combines governance, risk management, prevention, detection, response, recovery and supply-chain security.Part 37 of 40AI Governance: NIST AI RMF, the EU AI Act and Trustworthy DeploymentEnterprise AI requires a governance system for accountability, risk classification, evaluation, transparency, human oversight and lifecycle monitoring, not only model selection.Part 38 of 40Digital Innovation: Where Technology Actually Creates ReturnsTechnology produces value when it changes the business model, product, process or customer experience in a way that is difficult to copy and economically meaningful.Part 39 of 40Industrial IoT, Digital Twins and Edge OperationsConnected assets, edge computing and digital twins bring information technology into the physical operating system of factories, logistics networks and products.Part 40 of 40The Digital Operating Model: Connecting IT, OT, Data, AI and PeopleThe final step is not another technology layer but an operating model that connects strategy, architecture, processes, data, platforms, security, AI and frontline execution.
