Software Like Building A House

After arguing for decades that it is not so, I find out that I'm wrong. This is from a 2007 article on construction.
1. If it takes six months to build a house, then 85 percent of the time is spent on two activities: waiting on the next trade to show up and fixing mistakes.

2. Clemson's Professor Roger Liska conducted an analysis of productivity on the construction industry and found that the average construction worker operates at only 40 percent efficiency.

3. Critical shortages exist in qualified, skilled workers and labor issue futurist Roger Herman predicts the situation is only going to get worse.

4. Business Week's 2007 Investment Outlook Report indicates the return on equity (ROE) for all U.S. industries is 17.9 percent, while the ROE for the construction industry is a mere 9.7 percent, despite the recent construction boom.

5. Industry customers are frustrated with poor quality, confrontation, excessive change orders in quantity and dollar value, scheduling delays and litigation.

  1. Step 2, continue the epiphany by reading Deming.

    Realize that "waterfall" never worked anywhere for anything.

    Step 3, read Deming's profound changes. Realize that "waterfall" was an improvement on guilds, but was obsoleted around the 1930's or 40's.
