Problem-Solving Tools
Exploratory and Recording and
Analysis Tools
Agenda
!Defining the problem - Exploratory Tools
!Documenting the process - Recording
and Analysis Tools
!Determine proper worker - machine
relationships - Quantitative Tools (Part
II)
Methods Engineering Process
! Select project
! Get and present data
! Analyze data
! Develop idealmethod
! Present and install
method
! Develop job analysis
! Establish time
standards
! Follow up
Selecting the Project
!Considerations
!Economic
!Human
!Technical
Pareto Chart
!Developed by economist Vilfredo Pareto
!The critical few >> 80-20 rule
! Items of interest are identified and
measured on a common scale
Pareto Chart
Stream Diagnostic Chart
! List of problems classified under Man,Machine, Methods, Materials orManagement (or whichever isapplicable)
! The cause is attached to the tail of thearrow and the arrowhead is pointing tothe effect
! Focus on problem with most
outgoing/incoming arrows
Stream Diagnostic Chart Fishikawa Diagrams
!Cause-and-effect diagrams
!Occurrence of undesirable effect - the
fish head
! Identifying contributing factors or
causes - the fish bones
!Principal cause are also divided into
Man, Machine, Methods, Material,
Management, etc.
Fishikawa Diagrams Gantt Chart
!Project planning and control tool
!Shows anticipated completion times for
activities as bars plotted against time on
the horizontal axis
Gantt Chart
Job/Worksite Analysis Guide
! Identifies problems within a particular
area, department or worksite
Job/Worksite
Analysis Guide Other Tools
!Brainstorming (Structured and
Unstructured)
!Nominal Group Technique
!Check Sheet
Get and present data
!Documenting the present method
!Production quantities, schedules,
operation times, facilities, machine
capacities, special tools and materials
Operation Process Chart
!Chronological sequence of operations,
inspections, time allowances and
materials used in a process
!Gives manufacturing details at a glance
Operation Process Chart
Operation Process ChartFlow Process Chart
!More detailed than OPC
!Used for components rather than entire
assemblies
!Records non-production hidden costs
! Distances traveled, delays, temporarystorages
Flow Process Chart
Flow Process
Chart Flow Diagram
!Drawing of the plant areas involved with
a sketch of the flow lines indicating the
movement of material from one activity
to the next
!Uses same symbols as FPC
Flow
Diagram
Worker-Machine Process Chart
!Used to study, analyze, and improve
one workstation at a time
!Shows the exact time relationship
between the working cycle of the
person and the operating cycle of the
machine
Worker-Machine
Process ChartGang Process Chart
Gang Process
Chart Analyze Data
!Question every detail
!Why, Where, What, Who, When, How
