Traceability

Traceability is one of the most important aspects of the universal technology of accountability.  This article on traceability explains the notions of "trace", "track", "walk", "drilldown", "provenance", "audit trail".

  • Trace: Trace relates to following a complete path backwards from its current point to where it began.
  • Track: Track relates to following an emerging path forward from a starting point to follow where it goes.
  • Walk: The notion of "walk" is a step-by-step manual navigation through a system from a source to an origin or from an origin to it's source.
  • Drilldown: Drilldown vertical movement through an aggregation; you start at a high-level aggregation or summary like "total revenues" and "click" to see the underlying details of that high-level starting point.
  • Drill across: Drill across is the horizontal counterpart to drilldown. While drilldown takes you deeper into the details of a specific category, drill across enables you to jump from one information set to some other related information set at the same level of granularity. For example, drill across might allow you to switch between a sales database and an inventory database using a "product id".
  • Provenance: Provenance is the chronology of something from its origin to it's current location.
  • Audit trail: An audit trail provides a comprehensive record of the path or a log showing who did what when which provides transparency and accountability information. An audit trail relates to accountability and is a chronological record that provides documentary evidence of the sequence of activities that have affected at any time a specific operation, procedure, or event.

This document, Track-Trace-Walk, and this video by the same name helps you see how tracing, tracking, walking, and drilldown can be implemented within software when information is linked together effectively.  (i.e. if information is not linked together, then it is impossible to effectively move around within that information automatically and so any movement needs to be performed manually)

Overview

Imagine it.  Freedom from drudgery. Freedom from the toil of tedious, repetitive, mundane, monotonous tasks. Far less time needs to be spent fulfilling the role of "data janitor".  Time spent "transaction chasing" is significantly reduced. This overview is an attempt to take the work that I have done to understand XBRL-based reports and back into a framework for explaining those reports to accountants and software engineers building software for accountants.  I am now referring to this as model-driven reporting .   The sources of the information provided below are my " lab notebook " from December 2007 to October 2022; my Digital Financial Reporting blog from October 2022 until January 2025; Mastering XBRL-based Digital Financial Reporting ; and finally my Seattle Method  documentation. What I have tried to do is take the seemingly hundreds of incomplete, far too technical, typically nonstandard explanations that I have come across; take the good/best ide...

Knowledge Representation Approach

Image
Knowledge representation is simply organizing knowledge related to some area of knowledge into some physical form.  A knowledge representation provides an explanation of or description of the nature and structure of something. There are a number of different approaches that a knowledge representation might take, each approach having a different level of expressivity and reasoning capability.  These different knowledge representation approaches form a spectrum.  The following is a graphic which shows the expressivity and reasoning capability of different knowledge representation approaches: The following is a brief description of each of the different knowledge representation approaches which will help you understand the relative expressivity and reasoning capability of each approach: Name authority : A name authority provides what amounts to a dictionary or list which amounts to a flat inventory of terms with no relations expressed between the terms. This can be thought...

Complexity

Image
The world is complex.  But sometimes humans can come together, leveraging the power of agreement, and agree enough to create something useful in meeting some specific important aim and satisfying some agreed upon set of goals and objectives. A kludge is an engineering/computer science term that defines what is best described as a workaround or quick-and-dirty solution that is typically clumsy, inelegant, inefficient, difficult to extend and hard to maintain; but it gets the job done. The nautical term for a kludge is jury rig. By contrast, elegance is beauty that shows unusual effectiveness, grace, and simplicity. The alternative to being a kludge is  elegant simplicity . Elegant simplicity is achieved through complexity via hard work an, clever ideas, etc. Gall's Law states that a complex system that works is invariably found to have evolved from a simple system that worked. This principle emphasizes that effective complex systems develop from simpler, functio...
