| − | == Basic Principles ==
| |
| − | | |
| − | The following basic principles can help to find non-functional requirements:
| |
| − | | |
| − | * Authentication and Security

| − | * Small-Player Access to Services
| |
| − | * Traceability
| |
| − | * API Management
| |
| − | * Testing and Integration
| |
| − | * Service Behaviour
| |
| − | * Security and Redundancy
| |

| − | = Limitations =
| |
| − | | |
| − | When talking about limitations, we are in the '''World of Problems'''.
| |
| − | | |
| − | Based on the description of the current systems with its [[Architecture#Business Objects|business objects]] and [[Architecture#Workflows|workflows]] the limitations of todays systems can be analysed by making use of the [[Architecture#Perspectives|perspectives]].
| |
| − | | |
| − | == Methodology ==
| |
| − | | |
| − | # Limitations are identified in workshops based on the perspectives
| |
| − | # Limitations found are documented in a spreadsheet and in the UML model
| |
| − | # in order to cluster the limitations
| |
| − | ## duplicates are eliminated (in the spreadsheet)
| |
| − | ## dependencies between limitations are documented in the UML model
| |
| − | # then the limitations are grouped into limitation groups in the UML model
| |
| − | # for each of the groups the benefits and impacts are defined
| |
| − | # all the groups are categorized in low, medium and high priorities
| |
| − | | |
| − | == Criteria ==
| |
| − | | |
| − | The criteria to select potential limitations are:

| − | Based on sum of the scores of each criteria, multiplied with the weighting of the criteria an individual priority of each limitation results
| |
| − | | |
| − | <nowiki>Priority = (Score PA * Weight PA) + (Score L * Weight L) + (Score D * Weight D) + (Score V * Weight V) + (Score E * Weight E)</nowiki>
| |
| − | | |
| − | The priority of each limitation varies within the range of 1 and 10.
| |
| − | | |
| − | The higher the priority value the higher the ranking of a limitation.
| |
| − | | |
| − | === SAFe Ranking ===
| |
| − | | |
| − | The limitations were ranked additionally according to the SAFe Methodology (Scaled Agile Framework) in order to analyse the limitations in a longer planning horizon and set priorities accordingly.
| |
| − | | |
| − | The lower the SAFe for a limitation, the higher is the priority to act.
| |
| − | | |
| − | <nowiki>SAFe = Score E / Score VA / Score PA</nowiki>
| |
| − | | |
| − | * the higher the effort, the higer the SAFe, meaning, the lower is the priority to act.
| |
| − | * the higher the value added and/or the problem are, the lower is the SAFe, meaning, the higher is the priority to act.
| |
| − | | |
| − | == Conclusion ==
| |
| − | | |
| − | Based on the above described methodology the following 26 highly ranked limitations were found

| − | = Capabilities =
| |
| − | | |
| − | When talking about capabilities and gaps, we are in the '''World of Solutions'''.
| |
| − | | |
| − | Capabilities are derived from the [[Architecture#Limitations|limitations]] by taking into consideration the vision, governance and principles layed down by the CIOs.
| |
| − | | |
| − | Gaps result when future capabilities cannot be fulfilled with [[Architecture#Current Architecture|existing systems]] due to [[Architecture#Limitations|limitations]] of the existing systems.
| |
| − | | |
| − | They are the basis for the planning of development initiatives.
| |
| − | | |
| − | == Methodology ==
| |
| − | | |
| − | Based of the priorised groups of limitations the capabilities are elaborated:
| |
| − | | |
| − | # Definition of the capabilitity targets (what do we want)
| |
| − | ## out of the limitations
| |
| − | ## from platform requirements
| |
| − | ## from the vision
| |
| − | # Link the capabilities with the groups of limitations
| |
| − | # Elaborate the gaps between the groups of limitations and the expected capabilities
| |
| − | # Work out solution variants for the gaps, clearly describing
| |
| − | ## functionality
| |
| − | ## implementation effort (T-Shirt size, XS-S-M-L-XL)
| |
| − | ## implementation duration
| |
| − | ## affected stakeholders
| |
| − | # Assess the solution variants
| |
| − | # Decide about the final solution variants to be implemented
| |
| − | | |
| − | The result of this work is a backlog of solutions, that can be implemented in the '''World of Implementation'''.
| |
| − | | |
| − |
| |
| − | | |
| − | The capabilities can be found in the UML Model.

| − | | |
| − | == Weighting and Ranking ==
| |
| − | | |
| − | All capabilities found were evaluated and a weighting added to each of the capabilities. The following approach was used to rank the capabilities:
| |
| − | | |
| − | === Select Capabilities Along Limitation Ranking ===
| |
| − | | |
| − | # All limitations with a priority higher than 8 were selected, which results in 26 limitations
| |
| − | # All capabilities that solve these limitations were selected and the priority of the capability was set to the priority of the limitation with the highest priority
| |
| − | | |
| − | This results in '''22 capabilities'''
| |
| − | | |
| − | === Independent Evaluation of all Capabilities ===
| |
| − | | |
| − | All capabilities were evaluated independently as follows
| |
| − | | |
| − | <ol style="list-style-type: decimal;">
| |
| − | <li><blockquote><p>estimated the cost of each capability<br />
| |
| − | (3=low/<200k€, 2=medium/200k€-1M€, 1=high/>1M€)</p></blockquote></li>
| |
| − | <li><blockquote><p>estimated the benefit of each capability<br />
| |
| − | (3=high, 2=medium, 1=low)</p></blockquote></li>
| |
| − | <li><blockquote><p>calculated the SAFE-factor for each capability<br />
| |
| − | SAFE = 1/cost/benefit (SAFE varies between 0.11 and 1)</p></blockquote></li>
| |
| − | <li><blockquote><p>excluded the capabilities already ranked along limitation ranking</p></blockquote></li>
| |
| − | <li><blockquote><p>sorted remaining capabilities according to ascending SAFE</p></blockquote></li>
| |
| − | <li><blockquote><p>selected capabilities with a SAFE-factor = 0.11</p></blockquote></li></ol>
| |
| − | | |
| − | This results in '''14 capabilites'''
| |
| − | | |
| − | === Additional Capabilities ===
| |
| − | | |
| − | At the end additional capabilities were selected that have a link to one of the above selected capabilities, since these capabilities have to realized together with the already selected capabilities in order to achieve the expected result.
| |
| − | | |
| − | This results in '''18 additional capabilities'''.
| |
| − | | |
| − | The 54 selected capabilities (of 105, 51%) solve at least 75 limitations (of 201, 37%)
| |
| − | | |
| − | == Conclusion ==
| |
| − | | |
| − | The 54 capabilities found cover almost all clusters
| |
| − | | |
| − | [[File:Capa_conclusion1.png|border|center]]
| |
| − | | |
| − | Within these 54 capabilites, only capabilites for Braking Rules do not appear. Their ranking is too low to appear in the list of ranked capabilities.
| |
| − | | |
| − | When clustering the 36 main capabilities (without the related ones), the following situation shows up

| − | == Access Rights ==
| |
| − | | |
| − | For each of the above mentioned objects and all their attributes the accessibility on the future platform was defined. The following levels of accessibility were defined:
| |
| − | | |
| − | {| class="wikitable"
| |
| − | ! Closed
| |
| − | ! no data exchange is allowed
| |
| − | |-
| |

| − | |-
| |
| − | | Internal
| |
| − | | object is visible and accessible within the future platform if role using the object is involved in the corresponding traffic or transaction

| − | |-
| |
| − | | External
| |
| − | | object is visible and accessible by everybody
| |
| − | |}
| |
| − | | |
| − | per default, the access right to an object in the future platform, the level is Internal.
| |
| − | | |
| − | == Stakeholders and Roles ==
| |
| − | | |
| − | === Roles ===
| |
| − | | |
| − | Stakeholders accessing the objects on the future platform can have different roles. For each of these roles, the access rights to the objects can be different.
| |
| − | | |
| − | The following roles were identified:

| − | | Secondary Receiver
| |
| − | | yellow
| |
| − | | secondary receivers are interested in the information helping them to handle their business but the information is not mandatory to manage the business.
| |
| − | |}
| |
| − | | |
| − | == Object - Stakeholder Matrix ==
| |
| − | | |
| − | For each combination of object/attribute and stakeholder/role the access right of that stakeholder/role to the object/attribute was defined according to the defined access right levels.
| |
| − | | |
| − | [[File:Object_stakeholder_matrix.png|center|border]]
| |
| − | | |
| − | Example: access rights of Train Composition object and its attributes (grey fields: not of interest, green fields: primary receiver)

| − | The full matrix can be found here: [[https://teams.microsoft.com/l/file/E7EE7A71-3944-4DDE-AD73-BCDF5AB60DBB?tenantId=ef588fbf-8705-4200-a1a6-3be9fc3bb45b&fileType=xlsx&objectUrl=https%3A%2F%2Fxrail.sharepoint.com%2Fsites%2FRFFDigitalplatforms%2FShared%20Documents%2FEU%20data%20platforms%2FPhase%201%2FShare-2%2F01_Architecture%2FDocuments%2FObject_Receiver_Mapping.xlsx&baseUrl=https%3A%2F%2Fxrail.sharepoint.com%2Fsites%2FRFFDigitalplatforms&serviceName=teams&threadId=19:2ae0c3a808134862b280a79d6edb3cc4@thread.tacv2&groupId=e8f92e7a-8d91-4214-9fe7-28b21e040c7f| Object - Stakeholder Matrix]]
| |
| − | | |
| − | == Analysis and Conclusions ==
| |
| − | | |
| − | === Distribution of Stakeholder ===
| |
| − | | |
| − | [[File:Stakebholder_distribution.png|border|center]]
| |
| − | | |
| − | 63.3% of new stakeholders making use of the objects provided on the future platform are RUs. So RUs profit most from the addtional information provided on the platform.
| |
| − | | |
| − | On the other hand a third of the new stakeholders are none-RU stakeholders. This is an opportunity to sell the services of the new future platform to interested parties.
| |
| − | | |
| − | === Primary Receivers ===
| |
| − | | |
| − | [[File:Primary_receivers.png|border|center]]
| |
| − | | |
| − | 97.5% of the objects necessary for a primary receiver to do the job have an access level of internal, meaning that the receiver can access the object for the corresponding transaction or traffic.
| |
| − | | |
| − | === Secondary Receivers ===
| |
| − | | |
| − | [[File:Secondary_receivers.png|center|border]]
| |
| − | | |
| − | More than half of the objects can be accessed by the secondary receivers on an internal level. For a third of the objects/information the secondary receiver needs a contract or license to access the information.
| |
| − | | |
| − | Only 8 % of the objects/information is not accessible by secondary receivers.
| |
| − | | |
| − | === Consumption of Objects ===
| |
| − | | |
| − | [[File:Consumption.png|center|border]]
| |
| − | | |
| − | When looking at who is consuming information it is interesting, that customers, freight forwarders, intermodal operators, customs handlers and third parties profit as secondary receivers from the objects/information provided by the future platform
| |
| − | | |
| − | Existing receivers like RUs, wagon keepers and IMs only profit limited from the additional objects provided, but several new receivers like yard managers, port authorities and terminal operators can profit massively from the new platform.

| − | = Smart Services =
| |
| − | | |
| − | = Target Architecture =
| |
| − | | |
| − | This chapter describes the methodology to find the target architecture as well as the overview of the future target architecture with its basic framework concept.
| |
| − | | |
| − | The architecture is based on the [[Architecture#Capabilities|capabilities]] and [[Architecture#Smart Services|smart services]] and has the aim to close the identified [[Architecture#Limitations|limitations]].
| |
| − | | |
| − | It takes into account [[Architecture#Non-Functional Requirements|non-functional requirements]].
| |
| − | | |
| − | == The role of the RU community ==
| |
| − | | |
| − | In order to build up a future architecture, the RU community takes an important role.
| |
| − | | |
| − | It
| |
| − | | |
| − | * coordinates all RU interests | |
| − | * represents small and large RUs
| |
| − | * acts as a cooperation body between RUs, Wagon Keepers, IMs (RNE) and other interested third parties.
| |
| − | * has the force to harmonize strategically and tactically
| |
| − | * can provide lobbying and marketing
| |
| − | * can participate as strong partner in standardization efforts
| |
| − | | |

| |
| − | | |
| − | == Platform Approaches ==
| |
| − | | |
| − | === Todays Situation ===
| |
| − | | |
| − | Today, each participant in the railway business has to connect itself to a variety of tools and platforms in order to exchange information with other participants.
| |
| − | | |
| − | [[File:Platform_today.png|center|border]] | |
| − | | |
| − | === Pilot for new Digital Platforms ===
| |
| − | | |
| − | Instead of decomposing and rebuilding todays available and proven platforms and tools a hub could be built up that hides todays platforms and tools and provides unique access in one place. The functionality of the hub can be reduced for small RUs and can provide various interaction possibilities for large RUs.
| |
| − | | |
| − | [[File:Platform_pilot.png|center|border]]
| |
| − | | |
| − | The advantage of this pilot are:
| |
| − | | |
| − | * Fast integration of available platforms and tools | |
| − | * One single "Point of Contact" for RUs to exchange information
| |
| − | * Independence of the participants from changes in the underlying platforms and tools
| |
| − | | |
| − | === Evolution into Smart Services ===
| |
| − | | |
| − | Once these hubs are established, the underlying platforms and tools can be decomposed into smart services and new services can be added easily.
| |
| − | | |
| − | [[File:Platform_evolution.png|border|center]] | |
| − | | |
| − | In order to take the best out of the existing platforms, tools and systems, the best of all of todays applications can be selected and new smart services be built around this best breed.
| |
| − | | |
| − | The RU community has a lot of opportunities and unique selling propositions to build up such an integrated platform:
| |
| − | | |
| − | * Best Governance
| |
| − | * CEO Integration
| |
| − | * EU Lobbying
| |
| − | * 450 Members
| |
| − | * Long Term Experience (25 years +)
| |
| − | * All major use cases covered
| |
| − | * agile and flexible approach
| |
| − | * modern IT platform
| |
| − | | |
| − | == Organization ==
| |
| − | | |
| − | === Todays Situation ===
| |
| − | | |
| − | Each existing platform today has a management organization, a business team and an IT design and service team.
| |
| − | | |
| − | [[File:Orga_today.png|border|center]]
| |
| − | | |
| − | === Future Platform Organization ===
| |
| − | | |
| − | When moving towards an integrated RU platform a new organization has to be established, consisting of a new management organization, a new business experts group and one or more IT design and service teams. Participants of the new platform organisation have to take seat in the management and business experts teams of existing platforms that are not incorporated into the RU platform but interact with this new platform
| |
| − | | |
| − | [[File:Orga_future.png|border|center]]
| |
| − | | |
| − | == Platform Framework Concept ==
| |
| − | | |
| − | When building up an integrated RU platform, this platform has to provide, some important basic services in a framework besides the provisioning and distribution of data. These basic services are described in this platform framework concept.
