Implement and Validate– Under six sigma green belt – The final phase validate or verify which is about validating/verifying whether the design suits the requirements of customers and business. Before implementing the design, there are some quick steps or pre-requisites to be done to validate that the design is appropriate in normal working conditions which are –
- Pilot Run / Simulation – Even though the design is now complete and a pilot run is completed in the experimental set up, when it is implemented live on the floor there could be some changes in the output. So, before going live, a simulation in the usual factory set up is done. The team should try to use a factory set up (Ex – Layout of machinery) with raw materials, working conditions (Ex – Temperature), machineries and people (Skill level & knowledge) as in real time. All minute changes in the output and any hiccups faced during the process should be recorded. A detailed RCA (Root cause Analysis) should be done and the root causes for variation should be arrived at.
- Make Corrections – Along with the Control recommendations that we arrived at in FMEA in the design phase, the recommendations from this RCA should be added in the FMEA and implemented. It is better to use check sheets, with the list of CTQs and other key things that should be recorded during the simulation. This will help the team to ensure that all aspects of the design are performing as intended and expected. No single aspect will be left out from being monitored, however insignificant it might be. Corrections should be done to the process wherever necessary.
- Integrate Related Processes – In case the upstream and downstream processes need modification, to cater to the requirements of the new design, it should be done and a fresh Process flow chart should be created.
- Document the Process – The process should be documented in the form of Standard Operating Procedures, Process Manuals, Work Instructions, Supplier Manual, Quality Check Manual, Process flow charts, etc.
- Train the Employees & Communicate change – The Implementation plan that was drawn during the Design phase is now implemented. Employees who will be deployed in the new process, upstream and downstream process owners, Quality and training team, should be trained on the new process to be followed. One of the very critical tasks in this step is Change management, which is a challenge faced by many organizations. Depending on the organization culture and employees’ profile, organizations’ choose their methodology of adapting to the change. The new design is now implemented in full scale.
- Draw Control Plan – A Control plan is drawn to observe any variations in the output. The control plan will have the list of CTQ metrics to be monitored, a list of metrics that could bring out the standard and quality of the input materials and variables, and mid-process performance metrics. A review of these metrics should happen very frequently in the initial phase to identify and fix the gaps immediately. The project team should meet at a defined frequency to monitor the progress.
- Go Live – The process will now go live and is handed over to the operations Lead (the process owner). The transition should be smooth (as mentioned in the Implementation plan). He should be provided with the complete background of the design and the FAQs. This is the reason why the process manuals, work instructions should be prepared in full detail.
Implement & Validate- Various improvement methods are used which are:
Brainstorming
Brainstorming is a technique to systematically generate ideas usually to handle a challenging situation, from a group of people by nurturing free-thinking. There are several such opportunities in any organisation, e.g. Improving productivity, increasing sales, finding new business development areas, launching new products or defining new processes.
Multi-vari studies
Multi-Vari Analysis is a tool that graphically displays patterns of variation. These studies are used to identify possible X’s and/or families of variation. These families of variation can frequently hide within a subgroup, between groups or over time.
FMEA
The acronym FMEA stands for “Failure Modes and Effects Analysis”. It represents a technique aimed at averting future issues in project processes and eliminating risks that may hamper a solution.
Measurement system capability re-analysis
It is a method to re-identify the components of variation in the measurement. It is used to re-quantify the impact of measurement errors and to ensure the integrity of data used for analysis.
Post-improvement capability analysis
Post improvement re-measuring and re-analyzing the capability and performance of a process under review enables organizations to numerically represent and interpret its current state, and to report its sigma level. When done correctly, process capability analyses enable project team to precisely assess current performance in light of future goals, and ultimately, to determine the need and targets of process improvement. Process capabilities can be determined for normal and non-normal data, and for variable (continuous) and attribute (discrete) data alike.
