7 Introduction The FED contains the feasibility study of the project, identifying possible risks, costs, benefits and NDI/NCS components in building the E-Lockbox system for LivingAdvantage. Status The status of the FED is currently at the version 1.1 in the exploration phase. The previous version was 1.0.

8 Business Case Analysis Cost Analysis << Identify all possible cost either in monetary term or non-monetary term, such as hours spent, qualitative benefits for the project. Please note that you do not include the effort cost spent by development team, include only cost spent by clients. >> Personnel Costs << Identify all personnel-related cost from exploration phase to operation phase. Example can be found at ICSM EPG>Task: Analyze Business Case >> Table 1: Personnel Costs Development Period (24 weeks) Activities Valuation and Foundations Phases: Time Invested (CS577a, 12 weeks) Client: Meeting via , phone, and other channels [3 hrs/week * 12 weeks * 1 person] Client Representatives: Meeting via , phone, and other channels [1 hrs/week * 12 weeks * 2 people] Time Spent (Hours) Architecture Review Boards [2 hrs * 2 times * 1 people] 4 Development and Operation Phases: Time Invested (CS577b, 12 weeks) Client: Meeting via , phone, and other channels [2 hrs/week * 12 weeks * 3 people] Maintainer: Meeting via , phone, and other channels [2 hrs/week * 12 weeks * 2 people] Architecture Review Boards and Core Capability Drive-through session [2 hrs * 3 times * 3 people] Deployment of system in operation phase and training - Installation & Deployment [5 hrs * 3 times * 2 people] - Training & Support [3 hrs * 2 times * 4 people] Total Maintenance Period (1 year) Maintenance [3 hr/week * 52 weeks] 156 Total 156

9 Hardware and Software Costs << Identify all hardware and software-related cost from exploration phase to operation phase. Example can be found at ICSM EPG>Task: Analyze Business Case >> Development Table 2: Hardware and Software Costs Type Cost Rationale Server Free Provided by USC Amazon S3 Free for up to documents at ~200kb each (4.7gb) Offsite secure file storage and/or backup Production Type Cost Rationale Software - SSL $1499/year Secure login and transport encryption Certificate VPS hosting $39.99/month Isolated hosting for e-lockbox Amazon S3 Free for up to documents at ~200kb each (4.7gb) Offsite secure file storage and/or backup Benefit Analysis << Analyze benefits from this project. Benefits could be in the quantitative form such as more revenue, saved effort, and qualitative form such as increase of reliability. Example can be found at ICSM EPG>Task: Analyze Business Case >> Table 3: Benefits of elockbox System Current activities & resources used % Reduce Time Saved (Hours/Year) Salesforce upgrade ($60/user/month * 5 users * 12months) = $ % $

10 Total ROI Analysis << Calculate Return on Investment by using your cost and benefit analysis results and identify the breakeven point. Note, if you have hardware and software cost, it must be included in ROI calculation. For effort cost, if you use a salary as your calculation base, assume 10% annually increase. Example can be found at ICSM EPG>Task: Analyze Business Case>> Table 4: ROI Analysis Year nd half st half Cost Benefit (Effort Saved) Cumulative Cost Cumulative Benefit ROI Figure 1: ROI Analysis Graph ROI Year

11 Risk Assessment Table 5: Risk Assessment Risks Major functions selectable by customers are not known Document deletion process is unknown Case management workflow may not coincide with the other two partners views Additional details on report generation are needed Time logging and timing out could be potentially complex Customization level and details for clients need to be discussed Metadata types for uploaded documents are not known Permissions model for the different user roles are not clear Document management (logging, replacement and deletion)needs further information Complexity constraint: At the moment the development team is not confident we can implement all the client s requirements Risk Exposure Potential Probability Risk Risk Mitigations Magnitude Loss Exposure Further discussion with client for Further discussion with client for Further discussion with client for Further discussion with client for Further discussion with client for Further discussion with client for Further discussion with client for Further discussion with client for Further discussion with client for Attempt to negotiate with the client on delivery of the most important features. Level of Service Feasibility Table 6 LOS Feasibility Level of Service Goals LOS-1 Data Size: This system should support at least 5000 users and 5 documents for each. LOS-2 Security: All the documents must be stored securely. LOS-3 Mobile Compatibility: This system should be viewable on mobile Rationale Both Apache and MySQL can handle SSL certificates can help encrypt transport data. If we decide to use Amazon S3, it has functionality to generate one-time keys for a limited access time. Responsive design will let us adapt the layout based on screen size.

12 devices. LOS-4 Availability: This system should be down no more than 12hrs/monthly (excluding natural disasters) By using a VPS, we can guarantee better uptime. The host will also have a guaranteed uptime.

13 NDI/NCS Interoperability Analysis Introduction COTS / GOTS / ROTS / Open Source / NCS << Identify all candidate commercial off-the-shelf, government-off-the-shelf, research-off-theshelf, open source software, libraries, and net-centric services component that you are using/ plan to use. Also identify the purpose of each component. >> Table 7: NDI Products Listing NDI/NCS Products Apache/Nginx MySQL Laravel Amazon S3 Tesseract OCR Purposes Web server Database server PHP MVC framework File storage web service OCR processing library Connectors << Identify the connector, for example Appendix 8: In this project, we use PHP/MySQL Connector to enable the PHP web application to retrieve and query data from the database. >> Appendix 9: Legacy System << Identify the connector, for example Appendix 10: In this project, the development system has to be able to interoperate and works well with BusinessWorks version 5.2, which is a software system that the client is currently using. >> Evaluation Summary << Summarize the final selection of your interoperable NDI/NCS, its usage and its comment. Example can be found in ICSM EPG> Task: Analyze NDI Interoperability for NDI / NCS project. >>

14 Table 8: NDI Evaluation NDI Usages Comments Apache/Nginx Web server Positive points - Freeware - Widely used - Documentations available Negative points - No negative points MySQL 5 Laravel 4 Database server PHP framework Positive points - Freeware - Widely used - Documentation available Negative points - No support except for commercial licensing - Differences in table definition when running in strict mode. Positive points - Open source - Documentation available - Integrated unit testing - Database agnostic development - Database migrations - Light footprint Negative points - Command line dependencies - Developers will have to learn how to use it Amazon S3 File storage Positive points - Very low cost - Documentation available - Security tokens and limited access - Automatic versioning Negative points - Files stored offsite - Increased access time
