Software defines premium: the 7 Pillars of lifecycle control

The software-defined product began with a regulatory deadline and a new component. In the early 1970s, new United States safety and emissions regulations arrived at the same moment as the first microprocessors, and mechanical systems alone could no longer meet the performance and compliance demands placed on them. Software entered the product not as a feature but as the mechanism of control, optimisation and continuous improvement, and it never left.

The decades that followed built out the infrastructure. Electronic control units multiplied inside the product, diagnostics matured, and connectivity entered the mainstream. The introduction of 4G was the step change: real-time data flows from units in the field, remote services delivered without a physical visit, and the first over-the-air updates that could be scaled across a fleet rather than trialled on a handful of vehicles.

By the 2020s the equation had shifted again. Increasing system complexity, together with rising cybersecurity and safety requirements, moved software quality, traceability and lifecycle management from an engineering concern to something central to both operational performance and brand value.

The transition extends far beyond the automotive sector. Products across all industries are becoming connected, software-supported platforms, and business models are shifting towards lifecycle services, upgrades and data-driven value creation. Even conservative sectors such as defence and security are adopting software-centric architectures to secure long-term capability, interoperability and mission readiness.

Modern products are no longer defined by materials or mechanical design alone. Performance, reliability and long-term customer value increasingly come from software — how it is developed, deployed, updated, secured and managed across the entire lifecycle. Premium, in a software-defined market, is the capacity to keep improving a product that has already been delivered.

The 7 Pillars is a unified model for building software-defined products that improve over time, remain secure and deliver measurable operational value. It was developed by Viktor Eliasson and Jonas Hellberg at Diadrom and published in November 2025 as the white paper Software defines premium: The 7 Pillars on how lifecycle control creates real capability. It applies to any software-intensive platform expected to stay in service for a long time — automotive and defence platforms alike.

Each pillar names a capability an organisation has to hold: traceability of what has been built, structured processes for handling software, operational performance that rises after delivery, management systems people can actually use, services that sustain the customer relationship, secure and continuous upgrades, and sustainability as a designed outcome.

The pillars are interdependent rather than sequential. Over-the-air updates are worth little without traceability of what is installed where; fleet services depend on the same diagnostics that operational performance requires; sustainability is largely a consequence of the other six done properly. Organisations that adopt the model move from static product delivery to continuous value delivery, where software is the primary driver of premium performance.

The 7 Pillars of software-defined products, in the order set out in the white paper, are:

1. Delivery excellence — traceability of all software and hardware parts.

2. Innovation and co-innovation — processes for software handling, and business models for software-enabled products.

3. Operational performance superiority — increased uptime and added capabilities over time.

4. User-friendly design and experience — software management systems that drive operational efficiency.

5. Customer relationship and services — maintenance, fleet management and faster service delivery.

6. Constant upgrades — secure updates and over-the-air (OTA) capabilities.

7. Sustainability — longer lifetime, added capabilities, security and upgradable systems.

Each pillar is set out in full below, followed by the technical foundation an organisation needs in place to act on the framework.

Delivery excellence means full traceability of every software and hardware element in a product, so that industrialisation is stable, ramp-up is controlled and the supply chain can be verified. As systems become increasingly software-defined, visibility into versions, configurations and component origins is the precondition for all three. Software and hardware now evolve together, which means neither can be governed in isolation.

Without precise traceability, an organisation cannot ensure consistent quality, demonstrate regulatory compliance or resolve field issues quickly. In high-volume production, a minor deviation scales into a systemic failure faster than any manual process can catch it, which is why verified configurations rather than assumed ones are the working unit of delivery.

For commercial and defence applications alike, authenticating every part and every software package is now a baseline requirement rather than a differentiator. Traceability makes delivery predictable, reduces operational risk and underwrites customer trust in products expected to perform reliably over long lifecycles.

It is also one of the few places where a supplier claim can be checked rather than taken on trust. Diadrom is certified to ISO 9001, and any supplier in a software-defined supply chain should be able to demonstrate — not merely describe — how versions, configurations and component origins are controlled.

Innovation and co-innovation means structured processes for handling software, together with business models built for software-enabled products. New features, updates and improvements have to be developed, integrated and deployed reliably throughout the product's life, which makes build, integration and release discipline a competitive capability rather than an internal convenience.

Co-innovation extends that capability outwards. Aligning suppliers, partners and customers around shared architectures and roadmaps accelerates development and produces solutions that match real operational needs. In a supply chain where software crosses organisational boundaries as freely as hardware does, the interfaces between partners are where innovation either compounds or stalls.

As products become connected platforms, business models evolve with them. Value shifts from the one-time sale to continuous services, upgrades and data-driven offerings, all of which rest on secure, well-managed software underneath. Sustained innovation, rather than a sequence of static product releases, becomes the basis of differentiation.

Operational performance superiority means uptime and capability that increase after delivery rather than decay. In a software-defined product, performance is not fixed at the point of delivery; it evolves continuously through updates, optimisations and feature additions, which changes what operational performance describes — not the specification a product shipped with, but the capability it holds today.

Increased uptime is the most direct outcome. Remote monitoring, predictive diagnostics and rapid software intervention reduce unplanned stops and shorten recovery times, keeping systems available, responsive and mission-ready. Where a fault once meant a technician and an on-site diagnosis, a well-instrumented product surfaces the fault and shortens the time to fix it.

Equally important is the ability to add capabilities over time. New features, improved algorithms, security enhancements and performance upgrades can be delivered digitally, extending a product's relevance without physical modification. A product that improves throughout its lifecycle delivers sustained operational value, a lower total cost of ownership and a measurable competitive advantage.

User-friendly design in a software-defined product means the systems, interfaces and workflows that let people control, monitor and manage complex operations with clarity and precision. It extends far beyond appearance: it is the difference between a fleet an organisation owns and a fleet it can actually run.

Effective software management systems provide structured access to configurations, updates, diagnostics and performance data. Simplifying complex tasks and presenting actionable insight reduces operational burden and improves decision-making where the decisions are made. In practice, users need to track system status, follow up deviations, plan maintenance, deploy updates and manage capabilities through one coherent environment.

The result of that coherence is higher efficiency, fewer errors and faster response times. When design and functionality align, complexity turns into manageable, predictable, value-generating workflow, and the user experience becomes a direct contributor to operational excellence rather than a layer applied on top of it.

Customer relationship and services in a software-defined environment means continuous support — maintenance, fleet management and rapid service response — rather than one-time transactions. Those three stop being separate functions and become interconnected elements of a single service strategy.

Software-enabled diagnostics and monitoring allow issues to be identified earlier and resolved faster, reducing downtime and improving operational predictability. Fleet management systems add real-time visibility across distributed assets, which turns planning, utilisation and lifecycle decisions into matters of evidence rather than estimation.

Combining accurate data with streamlined service processes produces faster interventions, proactive maintenance and tailored support — the components of a relationship that outlasts the sale. Outstanding customer service in a software-defined product is ultimately enabled by software: transparency, responsiveness and the reliable operation of every unit in the field all trace back to it.

Constant upgrades means secure update mechanisms, including over-the-air capabilities, that keep a product improving long after delivery. Secure and continuous upgrades allow systems to meet new operational demands, address vulnerabilities and unlock additional value throughout the lifecycle — provided the update path itself is trustworthy.

Secure update mechanisms protect the integrity of each software package, validating authenticity and preventing unauthorised change. Over-the-air capability extends that process across distributed fleets, so updates reach the field quickly, safely and with minimal operational disruption. Rollback belongs in the same category of basics: an update that cannot be reversed is a risk carried by the operator.

In road vehicles this is no longer only an engineering preference. UN Regulation No. 156 requires a software update management system as part of type approval, and ISO 24089 sets out software update engineering for road vehicles. Both give this pillar a standard behind it that can be audited rather than asserted.

Handled properly, constant upgrades reduce downtime, maintain security posture and allow new features or optimisations to be introduced at scale. The product stops being a static asset and becomes a continuously improving platform, which is what long-term performance, reliability and customer trust now depend on.

Sustainability in software-defined products means extending product lifetime, reducing resource use and keeping systems secure and functional over decades. When capabilities can be added through software, and hardware can be upgraded or replaced without redesigning the entire system, products stay relevant far longer and generate significantly lower environmental and societal impact.

The mechanics are plain. Longer lifetimes reduce waste. Added capabilities extend usefulness. Security maintains trust and operational safety. Modular upgrades let a product evolve without replacing an entire platform.

For industries critical to society — transportation, energy, marine and defence — sustainability is a strategic responsibility as much as an environmental commitment. Software-defined products support resilient operations, protect communities and reduce the burden on global supply chains. In defence in particular, where platforms are expected to remain capable across decades of service, upgradability is the same argument stated as through-life capability.

Sustainability becomes a measurable outcome rather than a stated intention when systems are designed to last, to improve and to remain secure throughout their lifecycle. Diadrom's own environmental management system is certified to ISO 14001; inside the product, the decisive lever is design — a platform that can be upgraded is a platform that does not have to be replaced.

The framework only pays out if the technical foundation underneath it is coherent, spanning development, industrialisation, operations and service. Six requirements carry most of the load, and each one is testable — an organisation either has it or is running on assumption.

Start with end-to-end traceability of all software and hardware elements. Secure signing, configuration tracking and supplier integration together deliver controlled ramp-up, stable production and fast root-cause analysis when deviations occur. Add structured software handling on top: standardised build and integration workflows, supported by automated testing and reproducible environments, are what make continuous innovation repeatable, and they are the practical basis for service-oriented business models.

Operational excellence depends on high-availability architecture. Real-time diagnostics, predictive maintenance and remote recovery capabilities sustain uptime and consistent performance across fleets and long lifecycle horizons. Operators and technicians then need user-focused management systems that simplify version control, updates, configuration handling and health monitoring — the daily work of running a software-defined fleet.

Underpinning all of it are secure and scalable update mechanisms, local or over-the-air, that guarantee authenticity, support rollback and meet modern cybersecurity requirements. Finally, modular and upgradable architectures extend product lifetime by enabling hardware replacement, software enhancement and capability additions without major redesigns.

The seven pillars come down to one question that can be asked of any existing programme: does this product get better after it ships, and can the organisation prove it? An honest answer usually identifies one or two pillars where the capability is thinnest — most often traceability or the update path — and those are the ones worth investing in first, because the remaining pillars depend on them.

The full white paper, Software defines premium: The 7 Pillars on how lifecycle control creates real capability, runs to 13 pages and sets out the complete technical recommendations behind each pillar. Written by Viktor Eliasson and Jonas Hellberg in November 2025, it is available as a PDF from the white paper page.

Diadrom has built diagnostics for automotive and defence from Gothenburg since 1999, for customers including Volvo, Scania, Polestar, Saab, Thales and FMV. The product portfolio — Autotech Bootloader, Encrypt, Diag Com Stack, Diag Studio and Dolphin — exists to deliver these pillars in practice rather than describe them. The framework is a description of that work, not a theory about it.
