Day 17

Nah sekarang saatnya untuk memasukkan apa-apa yang kita bahas tadi kedalam frame work, dalam hal ini, Metode Cause n effect melalui Fish Bone. Sebelumnya mari kita pelajari dulu metode ini. Berikut saya ambil penjelasan dari sini.

Graphically illustrates the relationship between a given outcome and all the factors that influence this outcome. Sometimes called an Ishikawa or “fishbone" diagram, it helps show the relationship of the parts (and sub- parts) to the whole by:
• Determining the factors that cause a positive or negative outcome (or effect)
• Focusing on a specific issue without resorting to complaints and irrelevant discussion
• Determining the root causes of a given effect • Identifying areas where there is a lack of data
How to use it:
Specify the effect to be analyzed. The effect can be positive (objectives) or negative (problems). Place it in a box on the right side of the diagram.

List the major categories of the factors that influence the effect being studied. The “4 Ms” (methods, manpower, materials, machinery) or the “4 Ps” (policies, procedures, people, plant) are commonly used as a starting point.

Identify factors and subfactors. Use an idea-generating technique from Section 2 to identify the factors and subfactors within each major category. An easy way to begin is to use the major categories as a catalyst. For ex- ample, “What policies are causing . . . ?”

Identify significant factors. Look for factors that appear repeatedly and list them. Also, list those factors that have a significant effect, based on the data available.
Categorize and prioritize your list of causes. Keep in mind that the location of a cause in your diagram is not an indicator of its importance. A sub-factor may be the root cause to all of your problems. You may also decide to collect more data on a factor that had not been previously identified.

Helpful hint:
Consider using a positive effect (an objective, for example) instead of a negative effect (a problem, for example) as the effect to be discussed. Focusing on problems can produce “finger pointing,” while focusing on desired outcomes fosters pride and ownership over productive areas. The resulting positive atmosphere will enhance the group’s creativity.

Silahkan cermati dan fahami metode ini. Saya copy dari buku Basic Tools for analyzing data. Konsep ini menunjukan dalam memulai sebuah analisis masalah, kita harus memulainya melalui akibat atau goal lebih dahulu. Sementara saya akan membaliknya dengan meidentifikasi keadaan riil yang akan menjadi sebab untuk melihat akibatnya atau goalnya.
