© Gabriele Piccoli Enterprise Systems In the early 1990s developers realized the limitations of the functional approach This led to a class of standardized software applications that would enable and support integrated business processes These applications are known as Enterprise Systems (ESs)

© Gabriele Piccoli Enterprise Systems Provide native integration Attempt to support all components of the firm’s IT infrastructure. Defining characteristics: –Modular –Integrated –Software applications –Span all organizational functions –Rely on one database at the core. Custom developed or purchased off-the-shelf

© Gabriele Piccoli Characteristics of ESs Modularity –Enables the organization to decide which functionalities to enable and which ones not to –Allows for flexibility at the design stage –No need to pay for unnecessary components

© Gabriele Piccoli Characteristics of ESs Application Integration: –Events in one module automatically trigger events in one or more separate modules Data Integration –Data is stored in one central database

© Gabriele Piccoli Characteristics of ESs Configurable –Enterprise Systems are parameterized –Firms choose among a predefined set of configuration options during the implementation of the application –The firm can extend the capabilities of the standard application by creating “bolt-on modules” –This customization process further tailors the ES to the specific needs of the organization

© Gabriele Piccoli Advantages of Enterprise Systems Efficiency –ESs are able to rein in complex, generally hard-to-mange and support legacy IT infrastructures –Potential to reduce direct costs Example: No redundant data entry –Potential to reduce indirect costs by streamlining business processes and operations

© Gabriele Piccoli Advantages of Enterprise Systems Responsiveness –ESs can deliver improvements in the firm’s ability to respond to customers and market demands Knowledge Infusion –The application embeds the state of the art in industry practice –ES can be used to update obsolete business processes within the firm

© Gabriele Piccoli Advantages of Enterprise Systems Adaptability –Offer a degree of customizability rarely offered by off-the-shelf applications –Achieved through the use of configuration tables and bolt-on functionality

© Gabriele Piccoli Limitations of Enterprise Systems Standardization and Flexibility –Organizations are encouraged to implement as close to a standard version of the software as possible. –So called “Vanilla” implementation ensure that firms take advantage of the economies of scale created by the vendor –But flexibility is sacrificed by this approach –ESs are often referred to as software concrete Much of the adaptability only occurs during the implementation process. Once set, ESs are difficult to change

© Gabriele Piccoli Limitations of Enterprise Systems Limitations of best practice software –It will force the firm to adapt –It is unclear how “best practices” are defined –The “best” practice may differ for different firms –Its not enough to implement a software program to enact a new practice –A firm’s own best practices may not be supported by the new ES

© Gabriele Piccoli Limitations of Enterprise Systems Strategic Clash –A firm will have to choose amongst the set of business processes supported by the software –What if one of your unique and differentiating practices is not supported by the ES?

© Gabriele Piccoli The Hype Cycle Technology Trigger: When a new technology becomes available Peak of Inflated Expectations: When over enthusiasm and unrealistic expectations fuel rapid adoption Through of disillusionment: When failures become public Slope of Enlightenment: when the true benefits of the technology become apparent to the organizations Plateau of Productivity: the phase when the benefits and risks of the technology become widely understood and accepted

© Gabriele Piccoli Supply Chain Management The set of coordinated entities that contribute to move a product or service from its production to its consumption –Upstream Supply Chain –Downstream Supply Chain

© Gabriele Piccoli Modern Supply Chain Management Tight linkages between upstream (i.e., suppliers) and downstream firms (i.e., customers) Inter-organizational systems increasingly supported by the Internet Integration with enterprise systems Increasing attention to IT-enabled supply chain management

© Gabriele Piccoli Supply Chain Management

© Gabriele Piccoli Supply Chain Management Trends Radiofrequency Identification (RFID) A new frontier in SCM: –No line of sight requirements –Embedding potential –Writing capabilities –Storage capacity –Speed up the receiving process –Improve monitoring and control of inventories

© Gabriele Piccoli Enterprise Application Integration “Re-architecting” existing programs so that an intermediate layer, termed middleware, is developed between the applications and the databases Designed to make calls to the middleware layer rather than the other applications Streamlines maintenance process because changes to an application will not affect all the interfaces connected to it

© Gabriele Piccoli Typical Systems Infrastructure

© Gabriele Piccoli The EAI Approach ERP Legacy Application Database 1 Middleware Database 2 Legacy Application SCM

© Gabriele Piccoli Service Oriented Architecture A software design perspective focused on reusability of software components Enables the rapid creation of an application by the combination of pre-built services Built using separate but interoperable components

© Gabriele Piccoli Knowledge Management “All the value of this company is in its people. If you burned down all out plants, and we just kept out people and out information files, we should soon be as strong as ever.” --Thomas Watson, the CEO of IBM

© Gabriele Piccoli Knowledge Knowing What: Based on the ability to collect, categorize, and assimilate information Knowing How: Ability to recognize or create the sequence of steps that are needed to complete a task Knowing Why: Based on understanding of cause-effect relationships

© Gabriele Piccoli Knowledge Categories of Knowledge –Explicit Knowledge Can be articulated Codified Transferred with relative ease. –Tacit Knowledge The type of knowledge that individuals possess but find difficult to articulate

© Gabriele Piccoli Knowledge Management Set of activities and processes used to: –Create –Codify –Disseminate knowledge in the organization IT is a key component and enabler Aspects of knowledge management: –Creating –Capturing –Storing –Disseminating

© Gabriele Piccoli Creating Knowledge Knowledge creation is the first stage in knowledge management: –Generate new information –Devise solutions to existing problems –Identify new explanations for events

© Gabriele Piccoli Capturing and Storing Knowledge Enables the organization to: –Codify new knowledge –Maintain an organizational memory Content Management Systems (CMSs): –Applications used to capture and store knowledge –A knowledge repository is a central location and search point for relevant knowledge

© Gabriele Piccoli Disseminating Knowledge The last phase in a knowledge management initiative When knowledge is formatted and easily accessible, dramatic improvements in effectiveness and efficiency can be achieved.

© Gabriele Piccoli Business Intelligence The ability to gather and make sense of information about your business –A set of techniques –Processes –Technologies Designed to enable managers to: –Gain superior insight about the organization –Gain superior understanding of the business –Make better decisions

© Gabriele Piccoli Business Intelligence

© Gabriele Piccoli Components of BI Data Warehouse: –A data repository –Collects and consolidates data –Multiple sources Characteristics: –Large in size –Large in scope –Enabling data integration –Designed for analytics

© Gabriele Piccoli Components of BI Data Mart: –A scaled-down version of a data warehouse –Focuses on the needs of a specific audience –Smaller in scope, thus easier to build Online Analytical Processing (OLAP): –User-driven –Enables a knowledge worker to easily and selectively extract and view data from analytical databases

© Gabriele Piccoli Components of BI Data Mining: –The process of automatically discovering non-obvious relationships in large databases. –Used to analyze historical information –Machine-driven Possible Patterns: –Associations –Sequences –Classifications –Forecasting

© Gabriele Piccoli Customer Relationship Management CRM is a strategic initiative, not a technology CRM relies on transactional data and is designed to help the firm learn about customers Designed to use data to make inferences about customer: –Behaviors –Needs The objective is to create value for the firm by optimizing the relationship with each customer

© Gabriele Piccoli CRM Infrastructure

© Gabriele Piccoli The limitations of CRM CRM is firm centric –Only relies on transactional and behavioral data pertaining to the interactions of the customer with the firm Limited predictive ability –Some events are unforeseeable and only the customer knows about their occurrence

© Gabriele Piccoli Customer Managed Interactions In CMIs customer data is stored and managed by the customer CMI solves the limitations of CRM initiatives: –The customer’s personal data warehouse holds complete historical information –Future events are more likely known –Inferences are more precise Infomediaries may maintain customers’ data warehouses

© Gabriele Piccoli Customer Managed Interactions CMI is not only about the lowest prices –CMI completion may depend on lower price –More likely will stem from the quality of the recommendation CMI technology –The Internet provides the infrastructure for data transfer –Falling costs of storage make personal data warehouses a feasible alternative

© Gabriele Piccoli Open Source Closed Source –Proprietary software controlled by a software house –Prevent users from accessing and modifying the source code –Example: Microsoft Windows Open Source license characteristics: –Free distribution –Available source code –Derived works –No discrimination –Technology neutrality

© Gabriele Piccoli Models of Open Source Sponsored Open Source: –Foundations provide support and coordination to open source efforts Open Source Service: –Free licensing of the software, but charges for installation, support, training, and other services Professional Open Source: –A software house maintains tight control over the software programs that they sell

© Gabriele Piccoli Advantages of Open Source Robustness: More robust and more reliable than proprietary applications Creativity: Harnesses the creativity of thousands of developers Limited lock-in: Switching costs are lower than those with proprietary software Free License: Open source can generally be licensed for free

© Gabriele Piccoli Disadvantages of Open Source Unpredictable Costs: There are many potential costs along the way (TCO) Support Varies Widely Security: –Open source code may give an advantage to those who want to break its security since the code is available –But more vulnerabilities may be identified and corrected for since the code is open Compatibility: There is no guarantee about compatibility with other software

© Gabriele Piccoli Software as a Service (SaaS) Focuses on the services (i.e., functionalities) being provided, not on the physical products (software) being sold Application Service Provision (ASP) –A provider hosts and manages a standard application (e.g., Microsoft Word) –Clients access the application over a network (e.g., the Internet)
