AIS 5131 - MANAGING INFORMATION AND TECHNOLOGY Chapter 1: IT Governance and IT Strategy - Automation of basic high-volume - Part C activities - Enterprise resource planning (ERP) Business Intelligence (BI) system, a significant organization-wide investment, is now a commonplace Broad – field of IT that encompasses; - Investment in internet technology to Collection and analysis of information to distribute product & services and for assist; supply chain integration Decision making and assess the - Use of IT represents a new opportunity to organizational; use technology to have advantage over Performance – the one being assessed competitors - To maintain & extend a business’ Areas where BI is applied: knowledge and capital Applied to enhance a variety of business questions for measurement and analysis include: To effectively deliver BI, organizations need to design Process cost, efficiency and quality and implement a data architecture Customer satisfaction (with product & service Complete data architecture components: offering) The enterprise data flow architecture Customer profitability (including which (EDFA) attributes are useful predictors of customer A logical data architecture profitability) A business or per department structure Achievement of key performance indicators (from the staff & business achievement unit) Risk management Layers/Components of Enterprise Data Flow Architecture (EDFA) Factors which increased interest in BI: As a distinct field of study/IT activities, it would: 1) Presentation/Desktop Access Layer a) Increasing size and complexity of modern ★ THE TOP MOST LAYER organizations Where end users directly deal with information - Fundamental business questions need BI Includes desktop tools (e.g., spreadsheets), capability direct querying tools, reporting and analysis - The result is that even fundamental suites and purpose-built applications (e.g., business questions cannot be properly balance scorecards – BSCs, digital answered without establishing serious BI dashboards) capability Power users: have the ability build own queries and reports b) Legal requirements - Users that have greater access aka admin - Legislation: enforces the need of users companies to understand the “whole of Other regular/normal users: interact with business” data in predefined ways - Financial institutions: must report on all accounts/instruments of customers and 2) Data Source Layer all related transactions against those ★ THE LOWEST LAYER accounts/instruments (including any Sources of information: operational data, suspicious transaction patterns) external data and nonoperational data c) Pursuit of competitive advantage 3) Core Data Warehouse (DW)  Where the all/majority data of interest to an 8) Metadata Repository Layer organization, are captured and organized for Metadata are the data about data reporting and analysis Metadata later: should be comprehensive in Normally instituted as a large relational scope database (e.g., key information of a student) - Covering data as they flow between various DW: should hold normalized data for flexibility layers which include documenting, in dealing with complex and changing transformation, and validation rules business structures Information in the metadata layer: Normalized data – a clean data with Needs to extend beyond data structure specific and standard structure names and formats to provide detail on business purpose & context 4) Data Mart Layer Can be directly sourced by software Data marts: represents subsets information operating in the other layers from the core DW, which are selected and EXAMPLES OF METADATA: organized to meet business unit or business File name line needs (e.g., multi-purpose hall) File size ➔ may be relational databases or online Creation/modification date analytical processing (OLAP) data Attributes, i.e. hidden, read-only, system structure aka data queue Owner ➔ simplified structure compared to the Permissions normalized DW 9) Warehouse Management Layer 5) Data Staging and Quality Layer For scheduling of the tasks necessary to build Data copying, transformation into DW format & maintain the DW and data mart layers and quality control Administration of security Reliable data: get loaded to the core DW 10) Application Messaging Layer Data staging and quality layer: needs to deal Transporting information between the various with problems that are periodically thrown-up layers by operational systems such as changes to Encompasses generation, storage and account number formats and reuse of old targeted communication of control messages account and customer numbers (when DW still holds up original information of the entity) 11) Internet/intranet layer Basic data communication 6) Data Access Layer Browser-based user interfaces and Connect the data storage and quality layer Transmission Control with data stores in the data source layer Protocol/Internet Protocol (TCP/IP) networking 7) Data preparation layer Assembly and preparation of data for loading Logical Data Architecture into data marts A major undertaking that would normally be Usual practice: pre-calculate the values undertaken in stages loaded into OLAP data repositories to Reason for separating logical data model increase access speed determination by business domain: different Specialist data mining: requires preparation parts of organizations often deal with different of data transaction sets, customers and products Data (feed) mining: explores large volumes data to determine patterns and trends of Data Architecture information  Needs to be structured to accommodate the Important parts of the governance process needs of the organization most efficiently involve: Factors to consider include: ➔ BI initiatives to fund a) Types of transactions in which the ➔ Priorities to initiatives organization engages ➔ Measuring ROI of initiatives b) The entities that participate in these These parts are important because of the large transactions (e.g., customers, products, investment for BI infrastructure staff & communication channels) Scope: DW must be built in stages c) The dimensions important to the business Recommended practice: establish a - Dimension Hierarchies (e.g., product & business/IT advisory team that: organization hierarchy) - Allows different functional perspectives to be represented Data Warehouses (DWs) - Recommends investment priorities Storage capacity: not an issue - Establishes cross organizational benefit Goal: obtain the most granular or atomic data measures possible Final funding decisions: should rest by a Lowest level of data (attributes used for analysis technology steering committee (comprised by a purposes that can possibly be lost) vs. senior management) summarized data Data governance is important part of overall BI governance Aspects to be considered here include: Various Analysis Models used by Data Establishing standard definitions for data, Architects/Analysts business rules and metrics a) Context diagrams Identifying approved data sources Outline the major processes of the Establishing standards for data organization and the external parties with reconciliation and balancing which the business interacts b) Activity or swim-lane diagrams Deconstruct business processes Chapter 2: IT-Related Frameworks c) Entity relationship diagrams Depict data entities and how they relate Introduction on EGIT Framework ❖ Data analysis methods: important in developing Fail or succeed? Based on how they approach enterprise data model and use technology ❖ Knowledgeable business operatives (skilled EGIT frameworks: developed to help enterprise individuals) need to be involved in the process: leaders protect the integrity of their enterprise’s 1) For proper understanding of the business information assets and deliver value to purpose and context of the data stakeholders 2) For mitigating the risk of the replication of Frameworks: help organizations address suboptimal data configurations from existing business issues through governance and systems and-databases into the DW management of information and technology, by aligning high-level strategic objectives with operational objectives and direct work outcomes DATA GOVERNANCE Key to maximizing value: consider EGIT synergistically in the overall enterprise Effective data governance process: needed, to governance hierarchy. maximize the value of an organization obtained from BI initiatives  EXAMPLES OF EGIT FRAMEWORK 5.

Data Warehouse: is a collection of data from among the fields in a large relational various data sources of an organization (e.g., database sales, inventory, marketing, and the systems - GOAL: to extract the information from a data data, and other data from third-party sources) set and transform it into an understandable structure for use II. Data is then extracted into the DW Staging Area - The generated information can be used to using the ETL tools; having one staging area cut costs, increase productivity in some makes it easier for the ETL tools, subsequent regions data processing, and data transformation - ETL = Extract Transforming Load COBIT and ITIL III. Transferring all the data to a DATA WAREHOUSE COBIT 5 and ITIL are complementary Metadata – the data about data & one of the frameworks; you cannot choose one over the most important aspects of the data warehouse other - It helps data warehouse analyze, Common concerns/Shared interests of COBIT & identify, and find out what data is in the ITIL warehouse & where it is actually stored - both frameworks describe a number of (for the effective & efficient use of data) processes that should be established by a Summary data – form a part of data for query well-run enterprise purposes - In some cases, a COBIT process maps Usually loaded from ETL tools in batches directly onto an ITIL process Not real-time data in the warehouse COBIT – describes what should be done Raw data ITIL – describes how to do it IV. PRESENTATION LAYER – using an interface to ITIL gather information from data warehouse & present I.T. is the prime focus it in a way to make further decision It recognizes the primacy of the business OLAP (online analytical processing) – an It emphasizes that IT exists to support the approach to answering the multi-dimensional business but the bulks of its advice relate to analytical queries from multiple process matters internal to IT perspectives COBIT It consists of 3 analytical operations: Has the whole enterprise as its concern 1. Consolidation/Roll-up (enterprise perspective) 2. Drill-down It also advices on IT related issues but it also 3. Slicing & dicing recognizes that those issues are not limited to IT Reporting – using the generate from the professionals warehouse to understand how the business It is a whole enterprise framework has been doing, how it will do in the future, and what we can do to improve the business IMPORTANT CHARACTERISTICS OF COBIT & ITIL ★ COBIT and ITIL are both frameworks  - They both provide guidance that an - Complete 5 Assessments are based on enterprise can draw on to devise solutions capability rather than maturity that are appropriate to its unique situation - On objective scoring mechanism - Neither provides an implementation blueprint, a recipe book IT GOVERNANCE – ISO 38500:2008 Provide guiding principles for directors of ★ Both are based on real-world experiences companies on the effective, efficient, and - Confidence that they will be able to provide acceptable use of Information Technology (IT) practical advice, that they will work within their organization - Based on experiences drawn from a wide range of enterprises The purpose of this International Standard is to ★ Both can be used by any type or size of promote effective, efficient, and acceptable use enterprise of IT in all organizations by - Commercial, Non-profit, and Government Manage the IT investments properly organizations both large & small, and Improve the performance of the organization enterprises operating in many different Improve project governance countries Improve the competitive position of the organization ★ Over the last 10 or more years, ITIL has been Minimize IT risks adopted by a large of organizations that were Assure greater project success rates seeking to improve their IT services - It’s probably to say that it has had much 5 Facts on ISO 31000: Risk Management greater market penetration than COBIT 1) Promotes a safer workplace & enhanced - Many (in fact most) organizations will start compliance with ITIL 2) Universal set of guidelines on risk management ★ COBIT can drive even more improvement 3) It has 3 main sections: Principles, Framework, - It provides a means/supports auditing and and Process evaluation of IT activities in a rigorous 4) Sections make up the ISO 31000 guideline objectives and repeatable way 5) Use the guideline to form a risk management - There is no equivalent existence/sanctioned program means of evaluating ITIL service management practices ISO 20000: The International Standard for Service - A number of independent service Management management consultancies have developed ➔ ISO/IEC 20000 is the international ITSM (IT assessment services, but they are service management) standard. It enables IT proprietary & not necessarily built upon departments to ensure that their ITSM processes objective foundations are aligned with the business’s needs and ★ COBIT is designed to be auditable international best practices. - Processes, practices, inputs and outputs are The ISO 20000 standard helps organizations all given unique identifiers benchmark how they deliver managed services, - Interfaces between processes are defined measure service levels and assess their explicitly performance. It is broadly aligned with and draws ★ COBIT comes with an assessment framework strongly on ITIL®. than includes: - A training and certification scheme for ITIL and ISO 20000 assessors to ensure rigor and objectivity ★ ISO 20000 and ITIL have a close relationship. ➔ ITIL provides advice on ITSM best practices, including options adopted and adapted by organizations according to business needs, local circumstances, and the service provider’s maturity. ➔ ISO 20000, meanwhile, sets the standards that service management processes should aim for. Organizations can achieve independently audited certification to the Standard to demonstrate that they are following best practices.  SHORT ASSESSMENT: 1.
