Red Thread

Home/Red Thread

The red thread focuses on decisions and options related to traceability.


The red thread represents the minimum architecture steps which provide traceability, rigorous decision making and value management measured against real business outcomes.

Usage and Value

Usage and Value is achieved after a product/project is deployed. Many architects and organizations ignore the measurements of how well the product measures against the objects and key results that were used to justify it in the first place. The ITABoK heavily suggests usage information measured on dashboards against OKRs in retrospectives against the deployed

Agile DevOps

Agile DevOps delivery is the heart of most development and IT shops. The ITABoK makes plenty of room for both agile and traditional methods. The basis for the ITABoK is bottom up architecture, meaning architects are actively involved during delivery not in up front design. This means that architects are actively engaged with teams, projects,


Views and Viewpoints give the architect different ways to look at an architecture using different decision making and design paradigms. For example, one might look at the information view of an architecture to understand the data, information and entities in the system or systems. The availability of views is a hallmark of great architecture thinking

Quality Attributes

Quality Attributes are the cross-cutting concerns of an architecture related to its structure and quality attribute requirements. Scalability, usability, flexibility, etc are all considered as a part of the quality attribute assessments and design activities. Each area impacts the others so quality attribute design can be a very powerful tool in understanding the overall functioning


Decisions are the heart of architecture. Understanding why a decision was made, how it impacts the solution, how it interacts with other decisions is the core of a great architecture. Being able to trace decisions to cost, benefit and outcome is the pinnacle of delivery and design. The ITABoK is centered on making decisions easier,


Options are included hear separately but form part of the ITABoK Design Triumvirate (requirements, options, decisions). Understanding and identifying options for a particular design decision is a part of understanding the industry and maintaining and healthy current knowledge base of available technology and strategy offerings. We have included a modern architecture landscape which includes options


Requirements management is a full art and science but what the architect is interested in are Architecturally Signficant Requirements. These requirements come in many shapes and sizes but the architect is interested in requirements that impact structural issues (mostly quality attributes), value (measurable benefits and cost), and constraints (standards, compliance, risk).

Objective Key Results

Objectives and key results is a technique used to derive measurements of success and goals on a specific set of capabilities and the enterprise. Resources Goals - this article outlines the use of OKRs and KPIs to drive outcomes. Value Management - this article describes methods for describing and deriving value Learning shot:

Business Case

The business case provides a codified set of benefits, costs and considerations for a product/project. The ITABoK uses a lean business case tool called the NABC (need, approach, benefits, considerations). This tool is used as an input to prioritization and roadmapping though there is considerable overlap and concurrency in their development. In addition LBC take
