I recently did a course (Diploma in Company Direction) which was a lot like a mini-MBA. One of the teachers was someone who did Finance – after an hour or two of reading Balance Sheets, calculating Cost of Capital, he talked to us about Strategic Finance… What would you do if you had unlimited money? Really unlimited money? Right, now we just need to find a way of financing this… A vision without finance plan is just a dream… A finance plan without a vision is just numbers… This is the way I think about Enterprise Architecture: plan for turning strategic goals into reality Strategic goals for an organization without EA are just dreams Enterprise model / architecture without the strategic goals are just pretty pictures
Doing the thing right vs.Doing the right thing… First generation of modeling with tactical value – modeling inside one domain. New generation of modeling with strategic value – modeling across domains
How do you manage this process? What information links to what? How is this updated? How do you manage change? How can you measure risk?
With PowerDesigner one tool keeps it all together.
Which other spreadsheets (presentations/word documents) reference this spreadsheet? Which other spreadsheets use this formula? Which other spreadsheets were developed by this person? If I want to make a change to “Customer” at Sybase, what impact would that have? If I change a business process from calling at work to calling on the mobile, what needs to change?
PowerDesigner is the most effective tool that allows organizations to manage the ‘impact of change’ from business goals down to the technological implementations and be able to trace all technology changes directly to specific business goals.
Data Lineage: where did the data come from? What transformation processes? If I make a change to a component, what business processes will it affect? Which applications?
Also use Banking example
One of the primary requirements of IT is to keep management informed. But it's also to support the business in multiple ways. And this is one of the primary functions of the regulation called Basel, or Basel II. And it requires CEOs and CFOs to understand, and more importantly, report properly and truthfully, their financial statements. And within an audit, IT has to have controls and processes set up so that the information being reported is secure, but also that they can track the lineage of the data for any item within a financial report. And so, IT has to develop these processes for identifying violations, or even deficiencies in the way they're reporting information. And then also, how the corporation can assist through management, but also the auditors come in against those financial reports. These are all issues that IT has to support. And they can do that very effectively, through leveraging something like PowerDesigner, and more specifically, doing model-driven development through PowerDesigner.
Summary of the findings of the presentation.
Enterprise Architecture with PowerDesigner Andrew de Rozairo Business Development Manager EMEA
What is Enterprise Architecture? <ul><li>What are your business priorities? </li></ul><ul><li>What information / technology do you have? (AS-IS) </li></ul><ul><li>What information / technology you need? (TO-BE) </li></ul><ul><li>What is your plan to get from where you are to where you want to be? </li></ul>Enterprise Architecture is the Plan. It involves executive commitment, processes, methodology, … and tools
What are the different models used in Integrated or Enterprise Modeling? Technology Need – Identify topology of application, data, services, and network How – Modeling of the network topology, deployment architecture, etc. Application Need – Identify application integration, architecture, and deployment How – Modeling of use cases, classes, components, instances, etc. Drivers Need Objectives Goals Strategies IT technologies Economic Environment Regulatory Environment How Documents Requirements Use cases Business Need – Identify business processes, ownership, and usage How – Modeling of processes, organizations (people), services, etc. Information Need – Identify data independent of applications and processes How – Modeling of data items, entities, relationships, tables, etc.
Common modeling scenario – Silos of metadata Business Information Technology
Integrated modeling – consistent, integrated, managed Business Information Technology
The benefits of a single tool <ul><li>Seamless Integration </li></ul><ul><li>Consistent communication </li></ul><ul><li>Metadata Management </li></ul><ul><li>Impact Analysis: understand impact of change </li></ul><ul><li>Reduce the time, risk and cost of change </li></ul>Tools consolidation, cross-functional communication, better alignment between business and IT
Enterprise Architecture helps drive Business Decision making Technology Application Drivers Need Objectives Goals Strategies IT technologies Economic Environment Regulatory Environment How Documents Requirements Use cases Business Information Business Changes drive changes down to lower layers Technology Changes enable changes in higher layers
EA answers business questions <ul><li>What are the core business processes of each organization? </li></ul><ul><li>What are the business critical systems and applications used to support these processes? </li></ul><ul><li>What data is needed for core business processes? </li></ul><ul><li>What is the current inventory of hardware and software, and how does each component support business processes and data requirements? </li></ul><ul><li>What happens if I change: </li></ul><ul><ul><li>Hardware, software, database platform </li></ul></ul><ul><ul><li>Which processes will be affected, which SLAs… </li></ul></ul>
What are budget drivers for 2009? <ul><li>Consolidation / Cost-cutting </li></ul><ul><li>Outsourcing (in-sourcing, near-sourcing) </li></ul><ul><li>Compliance & regulation </li></ul><ul><li>Mergers & Acquisitions </li></ul><ul><li>Agility – faster time-to-market with products & services </li></ul><ul><li>Move to SOA? </li></ul><ul><li>All these initiatives involve significant change </li></ul><ul><li>Enterprise Architecture exists to help manage the risk, cost and time of implementing change </li></ul>
DWH change management 4500 tables,10000 ETL flows (mainframe, RDBMS, flat files), 600 Universes, 25000 reports, ODS, DataMarts, Staging Area “ We don’t dare make any changes to our Data Warehouse” Our systems have become too complex to understand the interdependencies enough to understand the impact of making changes without tools.
Consistent customer face and preparation for SOA “ We need to be able to access all of a customers information when ever there is an interaction. The days of 'faking it' are over. There needs to be a clear understanding of what all the information that is needed to answer any inquiry, and that information has to be readily available.”
Unlocking SAP metadata <ul><li>A customer needed to better understand their data and how to translate that into better business decisions, which is why despite the downturn and cuts in other IT projects, the CIO and CFO saw the investment in PowerDesigner and was one of the few projects not being put on hold as part of their cost reduction plan in response to the financial crisis. </li></ul><ul><li>Works with SAP, Siebel, JDEdwards, PeopleSoft, Oracle Apps </li></ul>
Ensuring compliance <ul><li>Financial: Basel II, Sarbanes-Oxley… </li></ul><ul><li>Telco: Call Data Retention </li></ul><ul><li>Retail: Visa Cardholder Security Program </li></ul><ul><li>Govt / Health: Data Privacy / Data Protection </li></ul><ul><li>Where and how am I storing sensitive data? </li></ul><ul><li>Which applications and business processes have access to this data? </li></ul><ul><li>How can I get the auditors off my back quickly? </li></ul>
Improved communication “ Communications between different groups has always included a certain degree of interpretation – that is a luxury that we can no longer afford.” – Ericsson
The value of PowerDesigner in an Enterprise Architecture project <ul><ul><li>Do less by hand – automatically document key dependencies and easily align business and IT </li></ul></ul><ul><ul><li>Enforce consistent standards and practices throughout IT with the most customizable and secure metadata management tool available </li></ul></ul><ul><ul><li>Reach decision consensus faster with automated communication between all disciplines through PowerDesigner’s unique Link and Synch technology </li></ul></ul><ul><ul><li>Reduce the risk, time and cost associated with change with complete cross-discipline impact analysis and change management </li></ul></ul>
