1. Making the Business Case for Single Sign-On (SSO) Solutions

2. What’s Inside:
This PowerPoint template will walk you through putting together the numbers you need to make a business case for Single Sign-On (SSO) in your organization
The accompanying Excel Calculator is designed for simplicity:
It befits a feasibility-level study; more complex analyses would require a more robust model
It is based on cash flow, not P&L
It has no macros
All data and assumptions are to be entered on one tab, the other tabs are for display only

3. Show Current State 1. Input current state data
Simply enter in values in the green boxes
The fields in yellow will be calculated by the model

4. Show Project Costs 2. Enter the project costs and discount rate
Estimate costs based on prior experience, market scan, or vendors’ indicative pricing
Discount rate can be usually obtained from CFO group

5. Show Target State 3. Enter in target state benefits by year
It is best to start with the last year, then back into how much of that benefit you’re likely to achieve by the end of each intervening year

6. Customize the Presentation
4. Customize the PowerPoint to fit your needs
Review the numbers in your completed Excel spreadsheet then cut and paste the exhibits into this PowerPoint presentation
Follow the format of presenting the current state, project costs, target state and investment analysis

7. Document Risks and Soft Benefits
5a. Include risks of implementing SSO
A new single point of failure could lead to additional issues around denial of service or lack of availability
A muffed implementation could lead to a rash of stolen credentials
The project as scoped could overburden the enterprise’s physical infrastructure and network, and could also complicate n-factor authentication procedures
There might be a certain amount of readiness work involved in getting legacy systems on board
Care must be taken to consider regulatory requirements prior to going live with a new SSO platform
5b. Include soft benefits of SSO
Vastly improved speed and ease of access would be transformational, but difficult to quantify

8. Make it Work
6. If you don’t like the answer, just change the assumptions
You can always go back and change:
Target state reduction projections and the forecast speed to attainment
The discount rate you’ll receive
