key XUCs in BDD format

GAPS = Goals > Assessment > P:roblems > Solution

Goals ( as Key XUC - Executable Use Cases in BDD format  )

GAPS Example

XUC = Executable Use Case ( to be valid it must defined as an executable or it can't be validated )

Goal> Expand Internet Access in a Rural Community using BPL - Broadband Power Line ISP

XUC 1 = As a user, when I authenticate on the app, I have Internet Access

Goals >> BDD format

As a registered user of the SCPT which provides ISP access

Given I have 

1. A compatible mobile device
2. And have access to the required network equipment ( Wifi router, modem )
3. With ISP access to SCPT 
4. And onboarded on the TG mobile app
5. And setup an account with SCPT
6. And purchased prepaid ISP access tokens in my TG wallet

When

I authenticate on my mobile device biometrically using the TG app

And I select the option for BPL ISP access

Then

The TG app 

1. Verifies my account credential for SCPT
2. And my wallet has available pre-paid ISP access tokens
3. And the TG app creates a ISP access session token
4. And forwards the token to the SCPT access application 
5. And the SCPT ISP access service creates a valid session for the user account

So

• The TG solution provides authorization to SCPT for ISP access

1. The user can connect multiple devices to that ISP access session
2. Providing Internet access 
3. To users and devices at that location

Assessments >> 

1. Users have compatible mobile devices
2. Users have multiple devices to connect for ISP access
3. Users have local ISP access via Wifi router and endpoint modem
4. Users authenticate to device biometrically without ISP access
5. TG identity network available on cloud-nodes and edge-nodes that are cloud connected
6. The SCPT ISP access solution can delegate authentication of accounts and authorization access verification to a 3rd party solution using SAML 2.0
7. The TG edge-nodes are optional and not required given the TG cloud-nodes are required
8. The TG edge-nodes would need ISP access to run the TG identity ledger
9. IF TG edge-nodes supported wireless connections to mobile devices and RAN the identity ledger on those nodes locally, then the edge-nodes could provide authentication and authorization WITHOUT iSP access BUT could not add or revoke credentials until ISP access was provided

Problems ( and Opportunities ) >>  

• Marketing capabilities presentations for demos and case study references can be done by sales

• Engineering for a client need or use case is solution engineering, needs engineering support up front

1. New solution creates many engineering decisions to validate ( even using existing resources )
2. Dependencies include:  mobile device, local Wifi router with modem for ISP access, ISP access account, ISP access tokens, ISP access
3. Solution works in locations where ISP access available
4. Limitations on ISP access locations
5. Limitations on ISP access bandwidth
6. Limitations on Wifi router range from modems
7. Limitations on Wifi bandwidth and signal quality
8. Power requirements for ISP network
9. Power requirements for local devices

Solution Steps  ( and Strategies ) >> to define solution and related decisions, trusts

Specific Solution Steps for XUC 1

1. Validate users have compatible phones for ISP access or equivalent Web app access for the ISP service and billing system and the TG app
2. Validate the BPL service can provide the signal quality, bandwidth, noise suppression required for the Internet access use case examples
3. Validate the VCE model for all stakeholders works
4. Validate the end to end solution architecture and services definitions
5. Validate the end to end solution security and governance and compliance requirements are met including relevant standards
6. Validate the existing billing system capabilities for user account setup, pre-paid ISP token credits
7. Validate the new TG identity verification app can integrate with the existing billing system using a SAML 2.0 delegated interface
8. Validate the TG user wallet service can hold the ISP tokens and can purchase more if authorized by the user
9. Validate the billing system can reduce the ISP token credits as the ISP service is used
10. Validate the OAP ( Operations Assurance Program ) is ready for a pilot test PTO ( Permission To Operate ) with key SLAs, Metrics, Impacts
11. Validate the user success using the BPL ISP solution, the billing app and the TG identity app in pilot testing
12. Validate the results of the pilot program are successful and any necessary changes have been made to the program to ensure future success

General Solution Process

• VCC model including partners ( all stakeholder groups are represented )

1. VCE model 
2. SAP - Solution Assessment Plan
3. OAP - Operations Assurance Program
4. EAP - Enterprise Architecture Plan - For Solution, For each protocol, the OSI stack architecture
