Lillas-Evans Failure Impact Analysis Methodology

Developed in early 2007, this methodology supports the development of reliable matrices to describe the impact of IT system failures on business clients who utilise an organisation's services electronically.

Consultants Pat Lillas and Grant Evans created the methodology to assist organisations with their analysis under the Sarbannes-Oxley regulatory regime.

Further benefit of this work will be in the wider IT environment where companies are building their maturity under the ITIL framework. It will be particularly useful for development of Disaster Recovery Planning, Business Continuity Planning, Availability Management and Incident Management.

A complete precis to be published by early June 2007.

This methodology also known as ELVIS - Evans Lillas Vital Impact Schema

See also their ground breaking work on Project Management - PELVIS - Project Evans Lillas Impact Scheme where, Project Implementation elements of Cost, Time and Quality, if combined with a 4th element of "equality", form the 4 points of a pyramid. Previously referred to as the Iron Triangle of Cost, Time and Quality, the addition of the consideration of "equality" adds the dimension that results in a Pyramid Structure. The Pelvis methodology proposes that if these elements have equality, the resulting Pyramid is equilateral, and therefore virtually indestructable, whereas, a stretch of any one element renders the structure unusable in that the resulting pyramid is severely distorted, and therefore contains little or no substance, and does not have a rotational symmetry.

By contrast, a symmetrical pyramid maximises the content space enclosed, and has rotational symmetry, i.e. no matter what constitutes the base, the result is identical.

Therefore, the Project Stakeholder obtains equivalent views on Cost, Quality and Time.

Therefore, for PELVIS, it can be seen that:

Cost + Time = Quality (and) Cost + Quality = Time (and) Quality + Time = Cost
