  • 1. DEMAND PLANNING LEADERSHIP EXCHANGEPRESENTS: The web event will begin momentarily with your hosts:July 25th, 2012 plan4demand
  • 2.  Goals for the Session Uncluttering the Process Managing by Exception Case Study: Statistical Optimization Statistical Forecasting Tips & Tricks Design Considerations The Bottom Line Q&A/Closing
  • 3.  Goal  Focus on common business challenges seen when evaluating companies who have implemented APO DP Objectives:  Talk through three key business challenges with recommendations for improvement  Design considerations when implementing APO DP  Key Takeaways
  • 4.  Take a “Building Block” Approach  Build Data Views which Align to DP Processes  Pointed Data View for key DP Processes - History Management - Statistical Forecast Management - Sales and Marketing - Final Consensus Forecast Management
  • 5. 5  History Management  Creating a data view that shows current and prior year historical demand (shipments, orders, etc.) as well as historical promotional information is key to enabling clean base history process  The end result is the creation of a historical base that is the input for generating a statistical forecast
  • 6. 6  Statistical Forecast Management  Build a Data View that reflects only base history and statistical base forecast in order to support the modify and adjust statistical forecast process  Note that in this example two reference statistical forecasts are present because this client generated statistical forecasts at various levels to support the forecast process
  • 7. 7 Sales & Marketing Management  Adjustments can be managed via two data views if not using an integrated technology approach (e.g. CRM)  Non-Promotional Adjustments such as distribution changes  Sales Promotions using APO’s promotion planning  Recall that the promotional and non-promotional volumes become historical reference points for the clean history process over time
  • 8. 8 Final Consensus Forecast  Typically most cluttered data view as components from the “Day in the Life” activities are combined to get a holistic view  Review is typically completed at a higher level (e.g. product family / key account or product across accounts)
  • 9.  Exception Based Management Typical Business Challenges  Too many business rules generating too many alerts. - Alerts set too rigid for the process’s maturity stage  Lack of education on using alert monitoring and alert profiles to better manage exceptions (e.g. Using thresholds for forecast alerts)
  • 10. 10 How many CVCs per Planner are being managed on a weekly basis? Make your selection on the right side of your screen A. 500 -1,000 B. 1,000- 10,000 C. 10,000-25,000 D. 25,000 +
  • 11. 11 SDP Alerts (e.g. Macro-Dependent Alerts)  SDP Alerts are based on the planning book structure and are calculated using macros Some typical business rules used to define macro alerts are:  Checking for new or discontinuations Potential risk of generating too many alerts: relative to product shipping from a new location  Good information but risk of chasing noise in the supply chain (e.g. rogue shipment)  Customer has not placed an order in the past x months  Forecast exceeding prior year sales by  If forecasting in weekly buckets could x% generate a lot of alerts!  Large differences between statistical  Does this make sense right after an and consensus forecast implementation?
  • 12. 12  Forecast Alerts  The system generates forecast alerts if the historical data upon which the forecast is based cannot be correctly described by the selected forecast model  APO DP uses forecast error limits  You can control the magnitude of alerts generated and alert priority by setting up a forecast alert profile and using threshold values
  • 13.  Statistical Forecasting Not Being Holistically Optimized Typical Business Challenges  Typical demand planner skill is solid from business/product knowledge  But lacks statistical forecasting skills  Implementers create a standard set of forecast profiles, trend dampening profiles, etc.  No post go-live checkpoints to assess if the standard approach is working  Demand planners not comfortable using statistical forecasting process available in APO
  • 14. 14 Let’s take a deeper dive into the statistical forecasting pain points and how to be comfortable using the tool… What Types of models are you familiar with within APO below? Select ALL that apply on the right hand side of your screen  Manual Forecasting  Linear Regression  Season + Linear Regression  Median Method  Croston’s Method
  • 15. 15  Statistical Models / Techniques to select:  5 – Constant  Copy History  4 – Trend  Manual Forecasting  Linear Regression  2 – Seasonal  Season + Linear Regression  2 – Seasonal trend  Median Method   6 – Automatic model selection 1  Croston’s Method  1 – Automatic model selection 2  External Forecast / No Forecast Model(s) are assigned to Profiles Profiles Assigned to SSelections
  • 16.  Based on business discussions and analysis of current environment, client possessed components of both “Aware” and “Functional” Largest area of opportunity was statistical forecasting and exception based management both available in APO
  • 17.  Forecast Review / Buy-In Approach  Worked with demand team to define representative set of products and customers to use for deriving proposed modeling approach for POS and Shipment demand  Reviewed historical demand patterns in APO DP to get a sense on which statistical forecast models / strategies to use  Reviewed statistical forecast results and conducted further model parameter tuning to get a reasonable result but not bias the forecast  Compared APO generated statistical forecast to Final POS Forecast (what is supplied by the client demand team)  Documented and shared findings with team by conducting several working sessions  Developed a Roadmap for Forecast Optimization
  • 18. 18 Understand History• Completeness and accuracy of data available• Group products based on similar demand patterns• This leads you to a Forecasting Model Type Pick Forecast Strategy (e.g. Seasonal Models) within Model Type • Profiles aligned to Forecast Strategy • Constant Models • Seasonal Models • Trend Models • Seasonal Trend Models • Holt-Winter’s (Strategies 40 &41) Build Selections ID • Seasonal Linear Regression (45) of products based • Models attached to Profiles on Model Type  When fitting models to data, it is often useful to analyze how well the model fits the data and how well the fitting meets the assumptions of the business

  • 20. 20  Creating a default user setting parameter for saving statistical model changes as a unique forecast profile:  In many cases a planner is interactively changing the statistical forecast for a product but does not wish to override the default forecast profile that is being used during batch processing for a product family / grouping  To guard against this happening the planner can go to User Settings  Own Data and then select the Parameter tab  Then in the “Parameter ID” type “/SAPAPO/FCST_GUIDS” and for the “Parameter value” type “X”  This results in the system saving any forecast profile changes in SDP94 as a unique forecast profile Note: Be knowledgeable about the level of aggregation at which the statistical forecast batch is executed and the aggregation level at which you are managing models, interactively
  • 21. 21 Efficient Use of Forecast Alert Profiles:  Below is the high level flow for managing forecast alert profiles (this demonstrates using interactive forecasting) 1. Forecast Profile Setup (tcode:/sapapo/mc96b) 2. Alert Profile Setup • Select forecast error metrics for (tcode:/sapapo/amon_setting) APO to calculate in Univariate • This is where you create, copy or 3. Interactive Demand Planning Profile tab delete a forecast alert profile (tcode:/sapapo/sdp94) • Within diagnostic group can define • Define which forecast alerts to display • Assign alert profile upper limits for error measurements. and establish threshold limits that • Execute the statistical forecast specify the alert priority (e.g. Info, • Forecast alerts selected in forecast Warning, Error) profile will be calculated • Can review on Forecast Errors tab and fine tune the model • Display alerts in SDP94
  • 22. 22  Efficient Use of Forecast Alert Profiles:  To review the forecast alerts generated by the system you can set up a forecast alert profile and specify the error metrics to be used as well as threshold values that define alert priorities (i.e. information, warning, error)  Many people use MAPE or MAD to measure relative variability (how much did I miss the forecast by) BUT ….  They also need to measure bias by selecting MPE or Error Total  Furthermore, if ABCD classification for the product is available you can further segment alerts based on that attribute so when reviewing MAPE and MPE based alerts using % thresholds you are doing so based on volume contribution
  • 23.  Build a Prototype and get the business engaged immediately…don’t wait until a task on a project plan Align Data Views and Key Figures to Demand Processes (e.g. Clean History / Develop Statistical Forecast / Promotion Planning / Review Final Forecast) Create Macro Alerts (i.e. business rules) that result in a manageable amount of exceptions Focus on Critical Training like statistical forecast and CVC realignment Segment Product Portfolio using a combination of ABC classification (volume) with demand pattern analysis (variability) - A convenient statistical measure to use is this coefficient of variation because it considers the variability relative to the mean
  • 24.  APO DP is a flexible & robust technology solution  With robustness comes the need to remove the burden of magnitude  By focusing on the smaller population (i.e. 80/20 rule) your organization will be able to use the statistical forecasting and alert monitoring capabilities in APO DP and do so in a manner which alleviates the need for a customized, high maintenance alternative
