Evolution of Æilus

Æilus has evolved from a practical value-flow methodology into a theory-driven value management system. This evolution was not a rebranding or a cosmetic refinement - it was a structural response to the limitations encountered while applying Æilus v1.x in increasingly complex socio-economic systems.

This article explains why Æilus v2.0 was necessary, what fundamentally changed, and how the introduction of Value Management Theory (VMT) reshaped the methodology into a coherent, extensible, and academically grounded framework.

Æilus v1.x: Practical Origins (2022)

The first generation of Æilus (v1.x), introduced in 2022, focused on measurable value flows and their optimization within organizations. Its core ideas included:

  • representing organizational activity as cyclic value flows
  • measuring delivered and consumed business value
  • introducing transformers as organizational units that convert incoming value into outgoing value
  • prioritizing work based on value-to-cost ratios
  • increasing transparency through value-based reporting

Æilus v1.x proved effective in addressing real organizational problems:

  • misaligned priorities across teams
  • difficulty measuring the contribution of internal units
  • inefficiencies in large, multi-team structures
  • lack of feedback about value losses

However, v1.x relied on implicit assumptions about value that were never formalized. As a result, several limitations gradually emerged.

Limitations of Æilus v1.x

As Æilus was applied across different domains - technology, operations, governance, and personal effectiveness - the following challenges became apparent:

  1. Implicit theory of value

    Value was treated as measurable but not formally defined. Different stakeholders often used incompatible interpretations of value without realizing it.

  2. Ambiguity between value and metrics

    Measurement instruments (points, money, KPIs) were sometimes mistaken for value itself, leading to metric-driven distortions.

  3. Lack of formal boundaries

    It was unclear where one value system ended and another began, making inter-system interactions hard to reason about.

  4. Unclear role of interpretation

    Differences between planned value and realized value were observed but not formally explained.

  5. Scalability limits

    As systems grew larger and more interconnected, value-flow optimization alone was insufficient to explain sustainability, value leakage, and systemic degradation.

These issues could not be resolved by adding more practices or metrics. They required a theoretical foundation.

Introduction of Value Management Theory (VMT)

Æilus v2.0 is built on Value Management Theory (VMT) - a formal theory that describes how value behaves in socio-economic systems.

VMT introduces:

  • a strict ontology of value systems, actors, value elements, flows, and roles
  • axioms defining fundamental properties of value (context-dependence, interpretational asymmetry, absence of conservation)
  • theorems describing systemic effects such as:
    • flow resistance
    • accumulation of anti-value
    • participation conditions
    • system sustainability
    • value leakage and inter-system dependency
    • scaling through interpretation

VMT explicitly distinguishes:

  • planned value (sender interpretation)
  • realized value (receiver interpretation)
  • retrospective value (post-hoc re-evaluation)

This separation made it possible to explain phenomena such as:

  • misaligned expectations
  • marketing and branding effects
  • overproduction and hidden losses
  • sustainability failures in value systems

Importantly, VMT is descriptive, not prescriptive. It defines what exists and what is possible, but does not dictate actions.

Æilus v2.0: A Theory-Driven Methodology

With VMT in place, Æilus could be redefined.

Æilus v2.0 is a value management methodology derived from VMT, designed to govern how value systems can be influenced without violating their fundamental properties.

Three-Layer Knowledge Architecture

Æilus v2.0 operates as a three-layer knowledge system:

1. Value Management Theory (VMT)

  • Describes the nature of value
  • Defines ontological entities and constraints
  • Independent of any methodology

2. Æilus Methodology v2.0

  • Defines principles, roles, processes, and governance loops
  • Specifies admissible interventions in value systems
  • Ensures alignment with VMT

3. Æilus Design Practice

  • Accumulates applied knowledge
  • Contains real-world Value System Schemas (VSS)
  • Focuses on patterns, cases, and design decisions

This separation prevents:

  • theory from turning into philosophy
  • methodology from becoming a cookbook
  • practice from degenerating into ad-hoc solutions

Role-Centric Operating Model

Æilus v2.0 replaces role-heavy hierarchies with structural ownership:

  • Value Transformer Owners manage value production within transformers
  • Value System Owners ensure system sustainability and coherence
  • Additional scaling roles (Flow Owner, Practice Owner, Domain Owner) are introduced only when complexity requires them
  • Æilus Master supports correct methodological adoption without owning value

This model scales by adding roles, not processes.

Why Version 2.0 Matters

Æilus v2.0 is not “more complex” than v1.x - it is more explicit.

It enables:

  • reasoning about value beyond metrics
  • managing interpretation as a first-class object
  • detecting hidden anti-value and resistance
  • understanding why certain optimizations fail
  • designing sustainable value systems, not just efficient flows

Æilus v1.x laid the practical groundwork.

Æilus v2.0 provides the theoretical and methodological maturity required for complex systems.


Æilus v2.0 represents a transition from value flow optimization to value system governance.

By grounding the methodology in Value Management Theory, Æilus v2.0 offers a rigorous, extensible, and transparent approach to managing value across diverse socio-economic contexts.

All current and future developments of Æilus are now explicitly marked as Æilus v2.0, reflecting this foundational shift.
