<>>> 8 0 obj The table below outlines each type of tree diagram, providing information which helps differentiate the trees by style and function. <> Figure 2 shows a better choice, with a factual answer in report language and in the scope of the project’s area of concern. Functional analysis assumes that behavior cannot be understood in isolation. %PDF-1.5 Better to revisit and reword such answers to more clearly propel the detail around “why.”, Figure 3: Another Pitfall – Branches That Do Not Answer the “Why”. 7 0 obj �9��7 >`�Vo*�F#.ˉ/Yݓ�*#��y�u]�x�8�_� �E��1j�]V!��~��,���΍����Η��nN�~��WduD�Ow%�ܠ��'������|��㊔� D#hy*�!�~M|Y��|@��Z3�2f��-w�z1�/�;\�w/3���;I��;7�Va�Í�-��:���OaQ��}�A⾧Qf�f��T����@LW�r|3N��Ū�x� �y�A���h �"z�Wv)��� ��"�� �m k\)Lf�|�:,���9Z������:�G��‚G[�?P!�gm�w��H����'�!���}�i��R[���*NtY�ļ��pц�9D���9B;)%�UB J]�.�����{Rrߕ-�~ ���K�/�L�`�A���r�}̶ M�?� x��YYo�F~7���G2��I1xƙ ���('m���ؤBR���oU�A6E@0K���>غ�o�ݳ^��W_����^o�M�x�������������A��j���믣�����ۛ����R� I probably don’t use each of the tools enough.

Every lower level in a KJ tree should be a good example of the data above, at the next lower level of abstraction. endobj For example, two clients attending a group treatment for post-traumatic stress disorder … The data and construction logic is what makes these four types of tree diagrams unique.

One or more functions delivered by a product or process, Describes factual situations without ambiguity, Describes factors (variables) that can change value, Uses positive, active verbs to describe the node’s functionality, Uses factual report language, free of judgment, emotion or inference. 10 0 obj is a comprehensive structural approach to generate a number of alternative solutions from the functions and sub functions. As a simple example Figure 4 shows the Function Means Tree for the tea making. Too often, an answer that is too vague, judgmental and/or outside the team’s area of influence (like “bad management” or “poor training”) gets posted in the tree as in Figure 1. Fault tree analysis (FTA) is a top-down, deductive failure analysis in which an undesired state of a system is analyzed using Boolean logic to combine a series of lower-level events. <> Methodology From discrete to functional data. Figure 1: Common Pitfall – Out-of-scope Answer, Figure 2: Better – Detailed and In-scope Answer, Another common pitfall in cause-and-effect work is branching to answers that describe “the parts of” the problem (where it is, when, etc.) This calls for a special “lens” that highlights the functions delivered. Experience shows, though, that there are enough pitfalls encountered and benefits missed that it is worth consolidating a few time-won guidelines and tips about applying them and explanations on subtle ways they can become inadvertently blurred with one another.eval(ez_write_tag([[580,400],'isixsigma_com-medrectangle-3','ezslot_0',181,'0','0'])); The focus here is on four kinds of “trees” or hierarchical diagrams that become part of many Six Sigma projects: Each of these trees has a specific thrust and strength that can be surprisingly challenging to capture when a project team tries to build one or more of them. endobj The organization of the functions into a function-logic, FAST diagram enables participants to identify of all the required functions. Intuition The term functional in reference to observed data refers to the intrinsic structure of the data being functional; i.e. The Function Analysis System Technique aids in thinking about the problem objectively and in identifying the scope of the project by showing the logical relationships between functions. The 14-day-old mulberry seedlings were independently treated with 200 mM NaCl and 200 mM mannitol.
