Introduction (FBD= fishbone diagram)
nFDB is a tool to find out relationships:
n
n
n
nUse in QM especially in automotive industry
nOne of the tool set used to create so called 8D report (8 disciplines=FBD+5WHYs+PA+QM)
nAnother tool : 5  WHYs – will be cleared later  Another tool : PARETO=PA analysis will be shown

Some chosen problems which could be find out during ERP support process I
nlong response time  to requirements
nrequirement is directed to unsuitable consultant
nbad documentation about service action (poor log)
npeople ask repeatedly same questions at different moments and different consultants are asked
nsolution of  disputes :complaint- standard service
npayment asked for supplied services
1.how much (to whom, type of  task, type of the error- see diagram
2.starting time for invoiced services, response time
1.requirement is handed over till the problem is  solved
2.time of starting solving -solved
3.start of implementaion of the bad object till end of testing

nlack of interest of the management of both parties
nright specification of reaction time
nspecification to the error types and related response times

Pareto tool : What is it ?
ntool to specify priorities
nwhich job have to be done earlier than the others
nwhich rejects must be solved firstly
nwhich product gives us the biggest revenues

Evaluation of set of rejects
nEvery reject is assigned to one Ishikawa tree
nEvery tree with empty table is handed over to chosen company of responsible experts
nAll tables are collected and evaluated
