Business Intelligence: A Managerial Approach nd (2 Edition) Chapter 3: Business Performance Management (BPM)

Business Performance Management (BPM) Overview 



1-55

Business Performance Management (BPM) is… A real-time system that alert managers to potential opportunities, impending problems, and threats, and then empowers them to react through models and collaboration. Also called, corporate performance management (M by Gartner Group), enterprise performance management (EPM by Oracle), strategic enterprise management (SEM by SAP)


Business Performance Management (BPM) Overview 



BPM refers to the business processes, methodologies, metrics, and technologies used by enterprises to measure, monitor, and manage business performance. BPM encomes three key components 





1-56

A set of integrated, closed-loop management and analytic processes, ed by technology Tools for businesses to define strategic goals and then measure/manage performance against them Methods and tools for monitoring key performance indicators (KPIs), linked to organizational strategy


BPM versus BI 

BPM is an outgrowth of BI and incorporates many of its technologies, applications, and techniques.  



 1-57

The same companies market and sell them. BI has evolved so that many of the original differences between the two no longer exist (e.g., BI used to be focused on departmental rather than enterprise-wide projects). BI is a crucial element of BPM.

BPM = BI + Planning (a unified solution)


A Closed-loop Process to Optimize Business Performance 

Process Steps 1. 2. 3. 4.

Strategize Plan Monitor/analyze Act/adjust

Each with its own process steps… 1-58


Strategize: Where Do We Want to Go? 







1-59

Strategic objective A broad statement or general course of action prescribing targeted directions for an organization Strategic goal A quantified objective with a designated time period Strategic vision A picture or mental image of what the organization should look like in the future Critical success factors (CSF) Key factors that delineate the things that an organization must excel at to be successful


Strategize: Where Do We Want to Go? “90 percent of organizations fail to execute their strategies”  The strategy gap 

Four sources for the gap between strategy and execution: 1. 2. 3. 4.

1-60

Communication (enterprise-wide) Alignment of rewards and incentives Focus (concentrating on the core elements) Resources


Plan: How Do We Get There? 

Operational planning 



Operational plan: plan that translates an organization’s strategic objectives and goals into a set of well-defined tactics and initiatives, resources requirements, and expected results for some future time period (usually a year).

Operational planning can be  

1-61

Tactic-centric (operationally focused) Budget-centric (financially focused)


Plan: How Do We Get There? 

Financial planning and budgeting 



1-62

An organization’s strategic objectives and key metrics should serve as top-down drivers for the allocation of an organization’s tangible and intangible assets Resource allocations should be carefully aligned with the organization’s strategic objectives and tactics in order to achieve strategic success


Monitor: How Are We Doing? 

A comprehensive framework for monitoring performance should address two key issues: 

What to monitor  



1-63

Critical success factors Strategic goals and targets

How to monitor



Diagnostic control system A cybernetic system that has inputs, a process for transforming the inputs into outputs, a standard or benchmark against which to compare the outputs, and a channel to allow information on variances between the outputs and the standard to be communicated and acted upon

1-64



Pitfalls of variance analysis 



1-65

The vast majority of the exception analysis focuses on negative variances when functional groups or departments fail to meet their targets Rarely are positive variances reviewed for potential opportunities, and rarely does the analysis focus on assumptions underlying the variance patterns


Monitor: How Are We Doing?

What if strategic assumptions (not the operations) are wrong?

1-66


Act and Adjust: What Do We Need to Do Differently? Harrah’s Closed-Loop Marketing Model

1-67


Performance Measurement 

Performance measurement system A system that assists managers in tracking the implementations of business strategy by comparing actual results against strategic goals and objectives 

1-68

Comprises systematic comparative methods that indicate progress (or lack thereof) against goals


Performance Measurement KPIs and Operational Metrics 



Key performance indicator (KPI) A KPI represents a strategic objective and metric that measures performance against a goal Distinguishing features of KPIs   

1-69

Strategy Targets Ranges

  

Encodings Time frames Benchmarks



Key performance indicator (KPI) Outcome KPIs vs. (lagging indicators e.g., revenues)



Operational areas covered by driver KPIs    

1-70

Driver KPIs (leading indicators e.g., sales leads)

Customer performance Service performance Sales operations Sales plan/forecast



The drawbacks of using financial data as the core of a performance measurement: 







1-71

Financial measures are usually reported by organizational structures and not by the processes that produced them Financial measures are lagging indicators, telling us what happened, not why it happened or what is likely to happen in the future Financial measures are often the product of allocations that are not related to the underlying processes that generated them Financial measures are focused on the short term returns



Good performance measures should:   





1-72

Be focused on key factors. Be a mix of past, present, and future. Balance the needs of all stakeholders (shareholders, employees, partners, suppliers, etc.). Start at the top and trickle down to the bottom. Have targets that are based on research and reality rather than be arbitrary.


BPM Methodologies 



1-73

Balanced scorecard (BSC) A performance measurement and management methodology that helps translate an organization’s financials, customer, internal process, and learning and growth objectives and targets into a set of actionable initiatives "The Balanced Scorecard: Measures (HBR, 1992) That Drive Performance”


BPM Methodologies Balanced Scorecard

1-74



In BSC, the term “balance” arises because the combined set of measures are supposed to encom indicators that are:     

1-75

Financial and nonfinancial Leading and lagging Internal and external Quantitative and qualitative Short term and long term


BPM Methodologies  

Aligning strategies and actions A six-step process 1. 2. 3. 4. 5. 6.

1-76

Developing and formulating a strategy Planning the strategy Aligning the organization Planning the operations Monitoring and learning Testing and adapting the strategy



1-77

Six Sigma A performance management methodology aimed at reducing the number of defects in a business process to as close to zero defects per million opportunities (DPMO) as possible


BPM Methodologies How to Succeed in Six Sigma

        

 1-78

Six Sigma is integrated with business strategy Six Sigma s business objectives Key executives are engaged in the process Project selection is based on value potential There is a critical mass of projects and resources Projects-in-process are actively managed Team leadership skills are emphasized Results are rigorously tracked

BSC + Six Sigma = Success (see Tech. Ins. 9.3)


BPM Architecture and Applications 

BPM applications 1. 2. 3. 4. 5.

1-79

Strategy management Budgeting, planning, and forecasting Financial consolidation Profitability modeling and optimization Financial, statutory, and management reporting


Performance Dashboards 

1-80

Dashboards and scorecards both provide visual displays of important information that is consolidated and arranged on a single screen so that information can be digested at a single glance and easily explored


Performance Dashboards

1-81



Dashboards versus scorecards 



1-82

Performance dashboards Visual display used to monitor operational performance (free form) Performance scorecards Visual display used to chart progress against strategic and tactical goals and targets (predetermined measures)



Dashboards versus scorecards 

Performance dashboard is a multilayered application built on a business intelligence and data integration infrastructure that enables organizations to measure, monitor, and manage business performance more effectively - Eckerson



Three types of performance dashboards: 1. 2. 3.

1-83

Operational dashboards Tactical dashboards Strategic dashboards



Dashboard design 

1-84

“The fundamental challenge of dashboard design is to display all the required information on a single screen, clearly and without distraction, in a manner that can be assimilated quickly" (Few, 2005)

4.

1-102

Create a root node and assign all of the training data to it. Select the best splitting attribute. Add a branch to the root node for each value of the split. Split the data into mutually exclusive subsets along the lines of the specific split. Repeat the steps 2 and 3 for each and every leaf node until the stopping criteria is reached.


Cluster Analysis for Data Mining 

  

  1-103

Used for automatic identification of natural groupings of things Part of the machine-learning family Employ unsupervised learning Learns the clusters of things from past data, then assigns new instances There is no output variable Also known as segmentation



Clustering results may be used to  







1-104

Identify natural groupings of customers Identify rules for asg new cases to classes for targeting/diagnostic purposes Provide characterization, definition, labeling of populations Decrease the size and complexity of problems for other data mining methods Identify outliers in a specific domain (e.g., rare-event detection)



k-Means Clustering Algorithm 

k : pre-determined number of clusters



Algorithm (Step 0: determine value of k)

Step 1: Randomly generate k random points as initial cluster centers. Step 2: Assign each point to the nearest cluster center. Step 3: Re-compute the new cluster centers. Repeat steps 3 and 4 until some convergence criterion is met (usually that the assignment of points to clusters becomes stable). 1-105

Association Rule Mining  

    

1-107

A very popular DM method in business Finds interesting relationships (affinities) between variables (items or events) Part of machine learning family Employs unsupervised learning There is no output variable Also known as market basket analysis Often used as an example to describe DM to ordinary people, such as the famous “relationship between diapers and beers!”


Association Rule Mining   



Input: the simple point-of-sale transaction data Output: Most frequent affinities among items Example: according to the transaction data… “Customer who bought a laptop computer and a virus protection software, also bought extended service plan 70 percent of the time" How do you use such a pattern/knowledge?  



1-108

Put the items next to each other for ease of finding Promote the items as a package (do not put one on sale if the other(s) are on sale) Place items far apart from each other so that the customer has to walk the aisles to search for it, and by doing so potentially see and buy other items


Association Rule Mining 

Representative applications of association rule mining include 



1-109

In business: cross-marketing, cross-selling, store design, catalog design, e-commerce site design, optimization of online advertising, product pricing, and sales/promotion configuration In medicine: relationships between symptoms and illnesses; diagnosis and patient characteristics and treatments (to be used in medical DSS); and genes and their functions (to be used in genomics projects)


Artificial Neural Networks for Data Mining 

In 2009, collaborative decision making emerged as a new product category that combines social software with business intelligence platform capabilities. In 2010, 20 percent of organizations will have an industryspecific analytic application delivered via software as a service as a standard component of their business intelligence portfolio. By 2012, business units will control at least 40 percent of the total budget for BI. By 2012, one-third of analytic applications applied to business processes will be delivered through coarse-grained application mashups. Because of lack of information, processes, and tools, through 2012, more than 35 percent of the top 5,000 global companies will regularly fail to make insightful decisions about significant changes in their business and markets.


The Web 2.0 Revolution 





1-153

Web 2.0: a popular term for describing advanced Web technologies and applications, including blogs, wikis, RSS, mashups, generated content, and social networks Objective: enhance creativity, information sharing, and collaboration Difference between Web 2.0 and Web 1.x Use of Web for collaboration among Internet s and other s, content providers, and enterprises


The Web 2.0 Revolution 





1-154

Web 2.0: an umbrella term for new technologies for both content as well as how the Web works Web 2.0 has led to the evolution of Web-based virtual communities and their hosting services, such as social networking sites, video-sharing sites Companies that understand these new applications and technologies—and apply the capabilities early on—stand to greatly improve internal business processes and marketing


Online Social Networking – Basics and Examples 

A social network is a place where people create their own space, or homepage, on which they write blogs; post pictures, videos, or music; share ideas; and link to other Web locations they find interesting. 



The mass adoption of social networking Web sites points to an evolution in human social interaction

The size of social network sites are growing rapidly, with some having over 100 million – growth for successful ones 40 to 50 % in the first few years and 15 to 25 % thereafter

Social Networks and BI: Collaborative Decision Making 

Collaborative decision making (CDM) – combines social software and BI 





1-161

CDM is a category of decision- system for non-routine, complex decisions that require iterative human interactions.
