My last article outlined our education roadmap for the next two years. This article focuses on one of those topics – “Function Models.”
The newly printed Function Analysis Guide focuses on the basics and provides a number of examples for projects, products and processes. Function Models continue to focus on function analysis, but offers additional techniques that supplement the basics. In a sense, they are additive and can be used as appropriate to the value study being performed.
Over the next six months (October 2016 thru March 2017) we will have a series of articles that will focus on the following Function Models:
- Customer Function Model
- Function Tree Model
- Function Cost/Worth Model
- Hybrid Function Model
- Other Function Models
- Summary of Function Models
Muthiah Kasi will start by discussing Customer Function Models which he and many others use for special applications. This technique was innovated by Thomas Snodgrass and Ted Fowler in the mid 70’s. It is a different style FAST template, which addresses specific functions of project, product or service. In short, the diagram models the Basic Function as well as four supporting functions which are considered basic and essential to the customer: “ASSURE CONVENIENCE,” “ASSURE DEPENDABILITY,” SATISFY USER,” and “ATTRACT USER.” These standard functions are used in every diagram. Kasi will illustrate examples of its application in the October issue.
The Function Tree Model has become popular as a way to perform function analysis in Canada and Europe. It reorients the traditional FAST diagram from horizontal how – why logic to a vertical logic. It is used primarily by European value specialists, and can be used for projects, products and processes.
Don Parker will discuss Function Cost/Worth Model. This technique is popular for construction projects. Many building projects organize cost estimates into assemblies or systems. Each of these systems has one or more functions. For example, an exterior wall system encloses space, excludes elements and expresses aesthetics. This system has a cost. By examining a variety of ways to perform these functions, the lowest cost alternative becomes the Worth.
In January, Bruce Lenzer, creator of the Hybrid Function Model, will discuss the technique. It is best suited for process value studies. Several aerospace entities use this technique as well as government contractors. The issue with processes is that the function statements are not sometimes enough to communicate the intent of what the function does or is expected to do according to Bruce.
No doubt there are other Function related models that are in practice today. Please share your techniques with us so that they can be published in Value World. During the next year we will be drafting a new Function Models Guide and we would like to include other appropriate methods that can benefit all.
