PRESENTED BY: NavjotSandhu The Innovator’s Toolkit- Techniques and tools for optimizing and finalizing designs
Agenda • Objectives • Process Capability • Predict the performance of your new solution • Robust Design • Make your design insensitive to uncontrollable influences • Design Scorecards • Develop a dashboard to track your design and its underlying processes • Discrete Event Simulation • Visualize and test your innovation through computer modeling
Agenda • Rapid Prototyping • Make a fast 3D model of your solution to explore its viability
Managerial challenge • Streamlining a products creation process to meet upper management demands, customer demands, and engineering guidelines • Create an infrastructure so products can be designed and tested quickly using repeatable processes and tools
Objective • Use tools to produce a design into a workable model that can be tested, while tracking changes and progress
Agenda • Objectives • Process Capability • Predict the performance of your new solution • Robust Design • Make your design insensitive to uncontrollable influences • Design Scorecards • Develop a dashboard to track your design and its underlying processes • Discrete Event Simulation • Visualize and test your innovation through computer modeling
Process capability • Engineers need to compare how well a design meets it’s performance expectations. • In the realm of innovation, we want to focus on predictive use. • Helps improve designs
Process capability - Steps • 1. Determine specifications • Come from customers, engineering calculations, or pre-evaluation • Make sure specifications are clear and unbiased • 2.Collect Appropriate Data • Quantitative data – Can be either short or long term (variable data or numbers) • Qualitative data- yes/no, a particular color
Process capabilities - steps • 3.Calculate Capability Metrics • Measure for central tendency’s • Helps to determine where the specifications of a product should lie • 4.Improve the Design or Process • Make it more robust to input variation • Tighten tolerances of specifications and its related processes for better performance
Process capabilities Moment of truth • Discussion • Examples • Bank is testing a new a kiosk for that provides customers with rapid approvals on refinancing mortgages • Measure customer reactions between request/information received – determined information should be displayed within 2 minutes. They expect .6 percent of customers to have wait time more than 2 minutes. If pressured with competition, they can redesign the kiosk to provide more information such as credit score, dollar amount of loan, etc…
Agenda • Objectives • Process Capability • Predict the performance of your new solution • Robust Design • Make your design insensitive to uncontrollable influences • Design Scorecards • Develop a dashboard to track your design and its underlying processes • Discrete Event Simulation • Visualize and test your innovation through computer modeling
Robust design • Helps reduce sensitivity of the innovation to uncontrollable noise variables. • Variation will occur through the lifecycle of the design through normal wear and tear. • Robust design helps predict the undesired behaviors of a design to minimize customer disappointment.
Robust design • In order to do this you need help from an experienced engineer and also have to know about the following techniques: • Performance and Perception Expectations • Axiomatic Design • Matrices of customers needs. • Design FMEA (Design Failure Mode and Effects Analysis) • Measurement of potential design errors • Design of Experiments • Design of all information gathering exercises where variation is present
Robust design - Steps • 1.Identify Customer Expectations • 2.Develop Conceptual Design • Create a high level design • 3.Identify Control Factors and Noise Variables • 4.Identify Potential Deterioration • Normal wear and tear, component wear down • 5.Experiment and Determine Optimum Design • 6.Determine Detailed Design Tolerances • Determine specifications that the design needs to operate within

Design scoreCards • Helps keep track of changes and progress • System Performance – Predicts how the overall design will perform against its expectations • Component Performance-Predicts of the performance of individual key components that affect overall system performance • Process Performance- Predicts the overall quality level of key processes that produce the product or deliver the service. • More robust a scorecard, more likely a problem can be fixed before customer dissatisfaction occurs
Design scorecards - Steps • 1. Identify the Critical Parameters of the Performance Score Card • Identify all relevant customer expectations for your design • For each expectations, identify the :i) type of variable(discrete, continuous) ii)measurement unit • Continous indicators are tracked by their mean and standard deviations • Discrete indicators are tracked by looking at their success rate
Design Scorecards - steps • 2. Determine Target and Specifications Limits on Performance Parameters • Obtained from customer input, regulatory requirements, or design functional requirements • Three scenarios apply: • i) more is better • ii) less is better • iii)achieve a specific target
Design scorecards- steps • 3. Predict the Performance Indicators • Predict what values the indicators should be, then these will be later compared to actual values • 4. Build the Overall and Individual Component Scorecards • Identify the critical components that significantly influence the overall system performance. • Identify their critical inputs ( weight, mass, area, etc..)
Design scorecard - steps • 5. Build the Overall and Individual Process Scorecards • Identify the critical manufacturing and/or service delivery processes and sub-processes • Build a score card for each critical process • 6. Interpret the Scorecard • Analyze the scorecards after there is enough data on them • Determine how much and what components and processes effect the overall performance the most • Consider what improvements can be made and where

Discrete event simulation • Computer based modeling approach that allows the simulation of scenarios • Saves time and money • Has to be done correctly in order to model real world situations accurately
Discrete event simulation- steps • Choose software • AutoMod, SigmaFlow, ProcessModel, Arena, iGrafx • Vary in cost and features • Develop process flow • Create process maps • Include sub-processes, decision points, and queues • Assign process attributes • For each process step, enter associated attributes which could affect the process flow or outcome
Discrete event simulation - steps • Determine resources and attributes • Determine the resources of the processes and sub-processes • Determine process entities and attributes • Determine the entities and their associated attributes that will be a part of the processes • Run trial simulations • Look for deficiencies in logic
Discrete event simulations - steps • Run actual simulations • Run simulations while varying attributes and values • Verify results • Build a prototype to verify design

Agenda • Rapid Prototyping • Make a fast 3D model of your solution to explore its viability
Rapid prototyping • Creates a 3-dimensional model of a new innovation or product design • Use this when design needs to be assessed by designers and manufacturing engineers • Need the following • CAD • Rapid Prototyping Machine
Rapid prototyping • Three techniques available • Formative • Turn raw material into the desired shape • Subtractive • Start with a large solid, then remove material to obtain desired shape • Additive • Layer material over and over until desired shape and position is acheived
Rapid Prototyping - steps • Input CAD data • Create a computer design with the correct dimensions and attributes of your prototype • Export Data into Stereolithography Files • Export CAD file into an .stl file • Select Material and Specify Process • Depending on machine, we need to select the material • Thermoplastic resins, polycarbonate, wax, powdered materials, plastics, metals • Stereolithography technique-stacks horizontal slices on top of one another
Rapid Prototyping • Create Rapid Prototype • Clean and Finish the Prototype
Rapid prototyping • Discussion • Examples
Lessons Learned • Turning a design into a product requires patience, know how, experts, and expertise • There are tools available that help cut costs, streamline processes, analyze designs, and allow for organized documentation of details • Most great products need to be designed, tested, and then redesigned
