1In This Session …Best practices to design SAP BusinessObjects DashboardsHow to get the right requirements for your dashboardsHow to conduct design for performance and size your system accordinglyTake a look at common design challengesSee several sample designs and demos of good operational, management and formatted dashboards, as well as dashboards in BI Workspaces and the BI Launchpad
2What We’ll Cover … Overview Getting the right Requirements (ASAP, RAD and Agile)Dashboard Design ConsiderationsPerformance Testing and Performance DesignThe BI 4.0 Environment and Dashboard DeploymentsWrap-up
3The “Waterfall Methodologies” Are Not Good for Dashboards The System Development Life Cycle (SDLC) methodologies, such as ASAP, are known collectively as “waterfall methodologies”They give a false sense of clear-cut stages and do not address substantial functionality changes during developmentIt is hard to fix missing functionality during integration testingThe waterfallSource: SAPThe challenge with ASAP is that users don’t know what they want until they see it …
5Where Do You Start — First Alternative Real exampleGet a group of five-to-seven people for a brainstorming sessionDraw the solution, knowing that it may look somewhat different once developedFocus on the use of space, graphs, navigation, available data, and the purpose of the dashboardsDo not design fixed format “reports”
6Building a Mockup in Excel Real exampleIf you can make a “mockup” in Excel, users can see what it may look like in XcelsiusUsers can now see what it may look like
7Prototyping the Dashboard Requirements Real exampleOnce the brainstorming is completed, you can create data in Excel and prototype the solution in SAP BusinessObjects DashboardsIt can be very time consuming to get the requirements right
8A Dashboard Accelerator Approach – Agile, JAD and RAD A Dashboard Accelerator is a group of bought, or pre-developed dashboards, to help companies develop their dashboards faster following a Rapid Application Development (RAD), JAD or Agile methodologyInteractive developmentOrientation meeting- high-level scope agreementShow dashboard in weekly UAT sessionsDemo accelerator dashboards in scopeRequest enhancements and new featuresMake enhancementsPerformance enhancements backend & front/endUnit testSystem testNo functional specs are written and the development time for a subject area can be as little as 4-10 weeks depending on back-end enhancements required and scope.Integration testGo-Live8
9What We’ll Cover … Overview Getting the right Requirements (ASAP, RAD and Agile)Dashboard Design ConsiderationsPerformance Testing and Performance DesignThe BI 4.0 Environment and Dashboard DeploymentsWrap-up
10Creating a Dashboard Standards A Dashboard template should be developed that standardize the font, colors, button locations, navigations and tabs. Spend serious time on this, it should become the global standard for all your dashboards.10
11Divide and Get Performance Link to Details WebI reportsDrill-down optionsSplit your dashboards into logical units and get new data when drilldowns are executed. This keeps the result set for each query small and also decreases the load time for each dashboard
12Build Several Dashboards for each Functional Area Avoid trying to create a single dashboard for each functional area.You will normally need 3-5 dashboards for areas such as accounts receivables, accounts payables, purchasing, sales orders, invoices, shipping etc…Build 2 to 5 WebI reports for more details and link them to the dashboards so that navigation is easy for end users12
13Formatted Number Based Dashboards Some dashboards may have little navigation and be number or key performance indicator (KPI) based similar to Crystal ReportsStatic informationBasic graphing of key numbersKPIs13
14Senior Management – Graphical Dashboards Dashboards for the senior management should be very graphically oriented.Consider using logos, and images instead of text for this purpose.Navigation should be very simpleFor senior managers, the ability to interact with the data (what-if), see performance numbers relative to plan, budgets and prior years are critical functionalities14
15A Real-World Example This project is for travel expense analysis The color codes communicate changes, year-over-yearGraphs can be displayed many waysNavigation can be done and can get new query result setsThis dashboard is based only on BW query and BICS connector; the cube is in SAP NetWeaver BW Accelerator and the dashboard therefore loads in less than 12 seconds
16A Real-World Example (cont.) Dashboards are most useful when compared to somethingThis dashboard is relative to a budgetNotice that all graphs can be displayed in many ways and that color coding is consistent across the dashboardsMake sure layout, buttons, and colors are consistently used
17A Real-World Example (cont.) This dashboard groups six different categories and over 30 lines into an easily readable table using a few lines and mostly colorsToo many lines and incorrect use of “bold” makes dashboards very hard to readDon’t cram too much into a single dashboard. Plan on multiple dashboards for each business area.
18A Real-World Example (cont.) Changes over time are typically tracked in the dashboardsDon’t just present numbers, plan on only showing changesI.e., in amountsand percentagesIn this dashboard, the graphs are sometimes hard to read, so we added filter selections. Use these carefully, since they are slow and make Flash files large.
19Dynamic Dashboard Option for Power Users Step 2 - Self Service to select any characteristic to filter on. Can select multiple characteristics to filter on also IE: Month, Plant, Material Group, etc.Step 1 – Provide a self service option to select a group of any of the many key figures available from a SAP BEx QueryStep 3 - Self service option to select any range of dates or selections. The dashboard is design to limit 13 characteristic key figures though.
20The Measures can now be selected to be displayed Step 4 –Select available key figures to display on chart.
21The Next Step is just to refresh the display Step 6 – Update the Key Figures to add more key figures.Step 5 –Select available key figures to display on chart.
22Adding more measures to the display and rearranging them Step 8 - Move SNP Forecast (MT) to the top of the list for a higher priority.Then click updateStep 7 –Add Revenue to selected Key Figures
23The OutputStep 9 – Notice SNP Forecast (MT) moved to the top and now has numbers on the chart.Step 10 – Revenue is now a selectable option.
24Controlling Characteristics Step 11 – Select Xref, a custom characteristic to describe a material hierarchy.Step 12 – Select Mesh and CLICK ‘apply’
25Key Figures are now filtered based on the selection
26Saving a Personalized View Step 13– Save this view as ‘Mesh and Mas Dashboard’Step 14 –Enter name and save, and this become your personal self-service dashboard view!
27Online Help System for Your Dashboards Online help is available for each dashboardThe online help system explainHow numbers are calculatedHow to read graphsWhat functionality is embedded
28MobileDashboards are web based and may be rendered on a mobile device.Devices that do not support Flash, can use HTML-5 based dashboards in the future, or you can download software tools such as Xwis to assist with the rendering on tools such as Apple’s iPad.With Flash version 11 installed, all dashboards may be rendered on a mobile device using the Microsoft or Android based operating systemsFurther optimization is also possible for older devices with low memory or low network capacity28
29The Strategic Dashboard Release Plan The strategic dashboard plan should clearly map out the vision for the next monthsMake sure you add the “phase-2” timeline for all areas, plan for enhancements, and communicate this early to all users
30The Dashboard Deployment Diagram The dashboard deployment diagram provides an overview of who has access to each dashboardYou should also provide a similar diagram that shows who can grant access to the dashboards. These are called “dashboard owners.”
31The Business Readiness Dashboard Checklist The purpose of the business readiness dashboard checklist is to make sure that a project is not merely an afterthought with little visibility, zero real sponsorship, and has a lack of communication, support, training, and organizational commitmentThere are reasons why many dashboard projects fail

33Dashboard Objects That Can Cause Slow Performance These are dashboard objects that you need to carefully consider before employing
34Excel Performance Considerations — What to Avoid The logic you build into your Excel spreadsheet is also compiled into the Flash file when you export itSince some “daisy-chain” functions are very time consuming, you should be careful not to add too many conditions in the dataLookup functions and conditioning that should be avoided include:LookupsMid strings (MID)Right and left strings (RIGHT/LEFT)Horizontal Lookups (HLOOKUP)Vertical Lookups (VLOOKUP)ConditionGeneral conditioning (IF)Count if a condition is true (COUNTIF)Sum if a condition is true (SUMIF)Complex logic and nested logic create large SWF files and take a long time to open. Try to keep as much of the calculations and logic in the query instead of the spreadsheet.
35The BO Sizing for Performance Dashboards SAP has provided a sizing tool for the BI environments. It is based on Flash and is actually a dashboard itself. Download it:Output Area (Sizing Results)Input Areas (items and users)This tool can help you size your BI 4.0 environments with a few key assumptions and inputs.
36The Sizing Tool – Entering Users First, you have to enter the estimated active concurrent users (ACU) for the following user types:Information ConsumersBusiness UsersExpert Users
37Dashboard User Classification The tool provides on-line definitions of the user types and guidelines on how to determine Active Concurrent Users (ACU). This is defined as approximate 10% of the active users.Many dashboard users is large organizations may be classified as Information Consumers . They may not wait 5 minutes between clicks, but typically do little drill-down and filtering.
38Dashboard Size Impacts The next step is to make an assumption on the size of dashboards.The sizing tool classifies small dashboards as having 25 rows in the result set, medium having 250, and large dashboards having 2,500 rows.Assumptions: the tool was based on supporting two queries per dashboards, and benchmarked was for accessing two relational data sources. One with 6 dimensions with 77,000 entries and 400,000 line items, and one with 6 dimensions with 7,000 rows and 40,000 line items.
39Dashboard Environment Sizing Output The output of the tool is measured in SAP Application Performance Standard (SAPS). 100 SAPS is defined as 2,000 fully business processed order line items per hour. It is a measure that hardware vendors can use to decide which of their configurations can meet your performance requirements. All hardware vendors are familiar with this measure and this is what you will provide them when requesting a hardware quote.
40Memory Requirements for Dashboards and BI 4.x The sizing tool also provide a sizing estimate for the hardware memory required for each of the tiers. This is measured in Gigabytes
41Saving Your Assumptions and Results Your BI and dashboard sizing effort can be saved or printed from the tool and you can have many scenarios
42Example of Dashboard Performance Foundation Real exampleModularize the data and create sub-sets of data for really fast dashboardingGeneric “metrics” data tables can be created for summarized KPI and scorecard dashboardsThe summary, or snapshot data can be accessed much faster than underlying data tables with millions of records
43Dashboard Performance Architecture – another example In this example, the company uses snapshots for performance reasonsReal exampleDashboards for executive usersPre-delivered SAP BusinessObjects Web Intelligence reports for casual usersAd hoc SAP BusinessObjects Web Intelligence reports for power usersThe dashboards are only built on the low-volume daily snapshot cube (this is also placed in SAP NetWeaver BW Accelerator for very high performance)
44The Dashboard Performance Checklist The hardware servers — Check sizingThe server locations and networks — Check loadsQuery review — Look at database & calculation time, & designInterface review — Make sure you are using the best for the data sourceDashboard review — Look at Excel logic, container usage, number of Flash objects, sorts, size of result set, and simplification opportunitiesIn-memory review — Look at cache usage, hit rations, and SAP NetWeaver BW Accelerator usageReview data sources — Examine if snapshots can be leveraged and look for possibilities to create aggregatesExamine compatibilities between browsers, Flash, and Microsoft office versionsReview PC performance issues — Memory, disk, and processorsPerformance is complex, look at more than one area (e.g., Web portal bottlenecks and LDAP servers)

497 Key Points to Take HomeGetting the right requirements require prototyping and interactive sessions with end usersPlan on many dashboards and don’t force too much information into a single designBuild different layouts for casual, executives and power usersLink WebI reports to the dashboards and keep the detailed information in thoseThe SAP BI 4.0x platform should be the preferred choice to deploy your dashboardsAvoid certain components of the tool and stay with ‘default’ templates for simplified design (i.e. NOVA)Plan your dashboard deployment as a larger initiative of BI self-service for your organization.
