A thorough analysis of IT applications and systems in most organizations should reveal many opportunities for savings and improved efficiencies. Application rationalization is a process in which an organization’s IT assets are thoroughly reviewed and analyzed to develop a plan for improvements across all systems. Application Portfolio Management (APM) is a process to maintain and optimize the Portfolio of applications and systems.
The Business Drivers for Application Portfolio Management
What are the issues and concerns addressed by Application Rationalization and Application Portfolio Management? The table below shows the issues from the Business Leaders, users, IT Management and software management perspectives.
Issues Driving the Need for Application Rationalization and ongoing Application Portfolio analysis
•Inefficient Legacy Systems
•Business Interruption from System downtime
•Business needs not being met by the IT Initiatives
IT Customer Complaints:
•Takes too long to get information
•Data accuracy is suspect
•Technology issues are affecting the efficiency of the business Processes.
•Cannot obtain reports needed in a timely manner.
•Manual data entry and re-entry is required.
IT Management Pains:
•The IT Asset inventory is too large to be maintained by the limited IT resources.
•The Business does not see the value added from IT investments – Results in IT not having sufficient funds to complete required improvements.
•Database Centralization is needed as data is entered in more than one place manually or kept in individual spreadsheets, or paper forms.
•Systems are not Retired prior to the point where they fail.
Software Management Issues:
•Costs include unused licenses as the license tracking process is inefficient.
•Software is in use that is no longer supported by the vendor.
•Maintenance costs are out of control.
•Duplicate applications for the same purpose.
•Underutilized applications that should be eliminated.
Application rationalization looks at the business processes along with the IT systems, analyzing procedural issues as well as system issues to determine what needs to be improved or fixed.
What Application Portfolio Management does for the business
Application Portfolio Management extends the value of IT to the business by ensuring IT is meeting the business needs. Application Rationalization will provide cost savings and improved efficiency of business processes.
Application Rationalization optimizes the operation of the IT systems and applications, ensures data accuracy and ensures compliance with regulations. From the business perspective, the analysis ties IT to the business strategy and streamlines and improves processes.
The first step in the process is to inventory all applications, systems and processes. Questions to be answered for the entire application inventory include:
• How are the applications being used and who uses them?
• What processes does each application support?
• What data is input and output to the application?
• What is being spent to maintain, support, upgrade?
• What is the business value of the application?
• What strategic objectives does the application contribute to?
• What are the technical requirements?
• What is the level of customer satisfaction with the application or system.
• What is the risk associated with the application or system.
• Is there sufficient support for the system?
• Is the system managed and supported well?
Answers to these questions provide a clearer understanding of the state of the IT assets.
Application Portfolio Management requires thorough analysis of processes, operations, data and systems to enable good decision making regarding plans for the IT systems and applications. The analysis should look at the relationship of each asset to process, function, capability and data input and output.
Tools used for the analysis include:
• Process flow diagrams,
• Entity Relationship Diagrams for each application,
• Application budget and support costs
• Enterprise Architecture,
• functional and technical specs, user lists,
• help desk data,
• Database Analysis (requirements and data map)
• Data/ Process/ App/ System Relationships
• Associated Process information (process efficiency etc.)
Analysis of this information will identify redundant capability, costly assets (high cost to maintain), determine underutilized assets and highlight downtime issues. This analysis will be combined with the process analysis to determine required activities to optimize the portfolio.
With regard to process, the first questions to be answered: are the processes written and are they accurate? Just like applications, processes need to be easy to use and follow. Feedback from those who use the processes will determine which processes need re-engineering. A review of all processes together will determine gaps, overlaps and areas where the process flow is not optimal. This analysis will also determine opportunities for process automation.
Data accuracy and accessibility are essential to efficiency. Is data entered in more than one place? This would indicate opportunities for integration of systems. Users need to confirm that data is easy to find.
While data is gathered separately for applications and systems, processes and data, the information must be cross referenced. It is important to look at the relationships between the processes, applications and data. Which applications support which processes? What data is collected for each process? Are there labor intensive processes that can be automated? The Application Portfolio analysis will determine improvements for processes, applications, database structure and data collection. Decisions will be made to upgrade, sunset, combine and replace applications.
The analysis provided in application rationalization provides a great opportunity for IT to provide business value in cost savings and improved efficiency. Establishment of an ongoing Application Portfolio Management process ties IT to business as it clearly demonstrates the business value of the IT strategic plan.
Application Portfolio Management is an ongoing process requiring update to the inventory, information, analysis and recommendations as capabilities are added and as applications are retired. In addition, the Application Portfolio must be monitored and re-evaluated to ensure it is contributing to the business strategy.
