Shipulski On Design

Archive for the ‘VOC’ Category

2009 is a tough year, especially for CEOs.

CEOs have a strong desire to do what it takes to deliver shareholder value, but that’s coupled with a deep concern that tough decisions may dismantle the company in the process.

Here is the state-of-affairs:

Sales are down and money is tight.  There is severe pressure to cut costs including those that are linked to sales – marketing budgets, sales budgets, travel – and things that directly impact customers – technical service, product manuals, translations, and warranty.

Pricing pressure is staggering.  Customers are exerting their buying power – since so few are buying they want to name their price (and can).  Suppliers, especially the big ones, are using their muscle to raise prices.

Capacity utilization is ultra-low, so the bounce-back of new equipment sales is a long way off.

Everyone wants to expand into new markets to increase sales, but this is a particularly daunting task with competitors hunkering down to retain market share, cuts in sales and marketing budgets, and hobbled product development engines.

There is a desire to improve factory efficiency to cut costs (rather than to increase throughput like in 2008), but no one wants to spend money to make money – payback must be measured in milliseconds.

So what’s a CEO to do?  Read the rest of this entry »

Al Hamilton, of Axiomatic Design Solutions, wrote a good article on how Axiomatic Design can be used to evaluate multiple design alternatives.

Here is an excerpt from the article:

 

Axiomatic design breaks the design process into four domains, shown in Figure 1.  The customer domain can be thought of as the voice of the customer (VOC).

1. The functional domain is initially populated by mapping the VOC into independent measurable functions. High-level functions are driven by the customer; lower-level functions are driven by design choices. Every function must be measurable.
2. The physical domain is the domain of physics, chemistry, math and algorithms.
3. The process domain is where the specifics of how the design parameters identified in the physical domain will be implemented.

Dr. Mike Shipulski, director of engineering at Hypertherm, a manufacturer of plasma cutting systems, has made extensive use of axiomatic design. Shipulski observes, “By first defining the functions we are to achieve, we align our problem solving on the right areas and broaden possible design opportunities. With axiomatic design, we have a framework for avoiding problems that are often detected only during system-level testing.”
