The following diagram illustrates the overall Use Case Process. It shows the basic stages of a release, going from M0 (release kickoff), to M2/M3 (API Freeze) and to code delivery in M4..

It illustrates 5 stages that the Use Case teams are concerned with, the High Level requirements, to the release plan, defining the use case, to data model development, to API freeze and code development.

Atomic requirements are expected to be grouped together to coalesce into a Use Case. And the Use Case teams would work on a set of related requirements to deliver a "minimum viable product". The requirements sub-committee tracks individual requirements, but this process page discusses a process at the Use Case level. Requirements are often subsumed within a Use Case, but the reverse is not true (a Use Case is not subsumed within a Requirement).

A new process starting R7 is trying to also introduce the concept of working on atomic requirements, which may have Requirements team working on just that one requirement.

A Use Case teams are cross-functional in nature: they are composed of a use case leader, developers/committers/contributors, and also (indirectly) the ONAP platform members & PTLs from components that need to be involved. Use case teams are dynamic in nature, they are formed when new use cases are defined.


Use Case Teams Process

  • MO PROJECT PROPOSALS

    • USE CASE TEAMS - The Use Case Teams prepare their proposals.
      • #1: BUSINESS DRIVER TEMPLATE - The Use Case Teams should develop their business driver template and consider their purpose and business impact for their use case. This would detail the executive summary, business impact, business markets, financial impacts and management and strategy. The template for the business driver case can be found here: Business Driver Template for Use Cases
      • #2: REQUIREMENTS SUB-COMMITTEE - Develop their proposals for the release which focus on defining their business imperatives.  When ready, the Team needs to present their business drivers and requirements to the requirements sub-committee. The Use Case owner would propose and select the requirements that would be worked on in that release. The presentation are given to the Requirements Sub-committee: Requirements subcommittee
      • #3: REQUIREMENTS PROPOSALS - After making a presentation to the Requirements sub-committee. Their requirements would then be put into the release proposed functional requirements page. An example for Release 7 (GuiLin) is at this wiki: Guilin release - functional requirements proposed list
      • #4: USE CASE DEFINITIONS - The team can then use the Use Case Template to fill out more details about their Use Case. Note: (see above), again, a Use Case is a comprised of a set of Requirements. The use Case Template can be found here: Use Case Tracking Template
      • #5: INTENTION TO PARTICIPATE - Teams can indicate their corporate intention to participate
      • #6: RELEASE TRACKING - Each release has a release tracking page. The page can be found here: Release Planning . You will need to clone
      • #7: PROJECT SUBMISSION, PROPOSAL, PLANNING - The TSC coordinates the project submission, proposal and planning. A project submission, the intention to participate is announced. The TSC reviews and provides its disposition on all submitted projects proposal. In Project Planning closure, the submissions from all of the new projects have been submitted in wiki their Release Planning materials. These are also tracked on the Release Planning page.
      • #8: MODEL PLANNING - If you have model impact add to the model planning page ONAP R7 Modeling High Level Requirements

  • WIKI LINKS References for the Use Case Teams at M0

    REQ-1 - Getting issue details... STATUS

  • Modeling team - At MO the Modeling S/C does MODEL PLANNING. The planning develops into “High Level Info-model Requirements”. These High level info-model requirements fall into 3 categories:
    • #1: NEW USE CASES - items from the expected Requirements/Use Cases in the release (Scope of modeling, continuing, introducing, standards updates). The Use Case Teams should engage the modeling team to propose new requirements into their release planning page. An example of the Modeling S/C planning page for R6 is here: ONAP R6 Modeling High Level Requirements
    • #2: REFINING EXISTING MODEL - Refining Existing info-model that has not made it to the information model. Previously designs that need to be added into information model.
    • #3: FORWARD LOOKING WORK (FLW) - Modeling future forward looking requirements.
  • Architecture - The Architecture team should be aware of any major updates coming from the requirements & use case teams. If there is architectural impact arising from your use case or requirements comprising your use case, you can make presentations at the Architecture sub-committee meetings. Changes may include impacts to the functional architecture, or platform architecture.
  • PTL - The Use Case teams should engage the PTLs to inform them that the requirements in the use cases may have impact to their particular platform component. This can be done via attending the individual component meetings or coordinated at the Use Case Realization calls. Often, the platform components each have a release planning page as well.


  • M1 PROJECT APPROVAL

    • USE CASE TEAMS - The Use Case Teams prepare their proposals. At M1 the project submission, proposal and planning have occurred with the TSC. Use Case teams are cross-functional in nature: they are composed of a leader, developers and also (indirectly) the ONAP platform members & PTLs from components that need to be involved. Working towards M1, the Use case teams are defining their requirements and starting to think about their Data Model. 
      • #1 RELEASE PLANNING TEMPLATE - Use the release planning template to help you think about your scope, minimum viable product, architecture, risks, and epics. The release planning template can be found here: Release Planning Template
      • #2 MILESTONE CHECKLIST - The milestone checklist template contains a master blueprint of all of the major areas of a use case that need to be tracked. The Use Case teams should discuss and fill out for themselves this milestone checklist, and particularly, the product management and release management sections (see below). The major topic areas of the checklist are: documentation (M4), security (M2), product management (M0/M1), release management (M0/M1), testing & integration (RC0-RC2) and development (M4). This checklist can be found at this wiki link: Deliverables for Planning Milestone Checklist Template
      • #3 PROJECT DELIVERABLES - The Use Case teams are defining their project deliverables which include the functional architecture, scope, and dependencies.
      • #4 MODELING TEAM SYNC - The model subcommittee team should become aware of the use cases for the current release. Use Case teams are expected to make presentations to the modeling sub-committee for use cases that may impact the information model. This should open a dialogue between the Use Case team and the modeling to identify model impacts and where there might conceptual overlaps to help streamline the design. The Use Case teams may also be agnostic to the broader information model and contact between the modeling sub-committee and the use case teams will also raise awareness of relevant information models that the Use Case teams will need. At this point, the Modeling sub-committee is using their release planning page to determine what to work on in a release. For an example see this wiki:  ONAP R7 Modeling High Level Requirements
      • #5 EARLY DATA MODEL GROUNDWORK - Because the information model feeds the data models, the Use Case teams should take into account the new updates in the information model as a basis for their data model. The Use case teams should be identifying three things which will help the Modeling subcommittee understand better the model impacts. This will help the modeling team identify areas where model impacts will be. The Use Case teams should define their use cases in more detail ideally using the inputs, outputs and data flows.
        • PRECONDITIONS - Preconditions are the Information the use cases consume.
        • POST-CONDITIONS - The post-conditions can capture the kind of information that is output from the use cases.
        • INFORMATION EXCHANGES - Component-to-component information that is passed, APIs, NBI and external interfaces helps to identify models.
      • #6 TEST CASES & AUTOMATION - To reach M1, a set of high-level test cases should be identified. Some consideration to testing automation for your use case can also get underway. These are important to eventually define in more detail, and link off of in the Use Case wiki for each team. Historically, each use cases has had dedicated testing & integration pages created from either ONAP's integration team or each Use Case team's integration group.
      • #7 REQ-1 - Create your requirements JIRA. Which will be used to track your requirement/use case work in the TSC. Make a Clone ++ of REQ-1. You can listen to the recording of how to do that at: Use Case Realization Call: May 6, 2020

      ONAP R7 Modeling High Level Requirements

      #5REQ-1

      REQ-1 - Getting issue details... STATUS

    • Project & Release planning tables
    • Modeling team The info-model plan is established by the modeling team which summarizes the modeling requirements for a release. The model planning follows a template that is worked by the modeling team. The release platform Information model updates begin. An example template for R7 (Frankfurt) can be seen at this Wiki: ONAP R7 Modeling High Level Requirements
      • #1: Modeling TEAM SYNC - The Use Case teams need to engage the Modeling Sub-committee to make the team aware of potential model impacts arising from their use cases. The modeling team should also become aware of those at a high-level what impacts a use case might have to the release information model. The use cases also need to get into the ONAP Modeling High-level requirements planning page.
    • Architecture - Every release, the architecture sub-committee refines four things: (1) the release functional architecture, (2) impacts arising from component architectures, (3) architecture impacts from requirements & use cases, and (4) architecture enhancement (e.g. new flow updates):
      • #1: FUNCTIONAL ARCHITECTURE IMPACTS - Each release the functional architecture is updated. A link to the functional architecture can be found here: Architecture. The Use Case teams should become aware of proposed functional architecture updates. The Use case teams can reserve some time on the Architecture sub-committee team meeting to align the use cases with the functional architecture and learn about new updates. The Architecture lead (PTL) can also flag impacts of the functional architecture to individual use cases and vice versa.
      • #2: PLATFORM ARCHITECTURE IMPACTS - Each platform component (e.g. A&AI, SO, SDN-C etc) may have architecture changes for the current release. At M1, those should be in the proposal & planning phases within the architecture sub-committee. Use Case teams should become aware of new impacts to the Platform components arising from news use cases & requirements. The idea is that the use case leads would queue some time in a architecture S/C call (or hold a 1-off meeting) to discuss the use cases that may impact platform components for that release.
    • Components (PTL) - Each of the ONAP platform components (e.g. A&AI, SO, Controllers, SDC etc) may be impacted by new use cases. Having the use case leads engage PTLs.
      • #1: COMMITMENT & TRACKING - The use case teams need to engage the Platform component teams and the PTLs if they have impact to that Platform components. Requests for changes to components need to be tracked & get commitment from the PTLs. Ideally, engagement of the PTLs (component lead) should be initiated from the Use Case teams. The Use case team members can attend the component weekly calls to raise awareness. The component teams need to Identify and track Use case impacts in the release planning page. 
      • #2 RELEASE TRACKING PAGE - The release tracking page also tracks Use Case impacts for each of the platform components. For example in R6 you see this wiki: Release Planning


  • M2 REQUIREMENTS & FUNCTIONALITY FREEZE

    • USE CASE TEAM ENGAGEMENT -
      • FUNCTIONALITY IDENTIFIED - The Use Case/requirements functionality has been specified, agreed to and frozen. No new visible functionality is to be added to the use case after M2.
      • FUNCTIONAL TEST CASES - Each Project team at M2 has defined and documented their Functional Test Cases. The integration teams have been engaged, and each individual project will likely have its own dedicated integration team wiki page.
      • DESCOPING IDENTIFIED - At this point, if functionality cannot be delivered, the Requirements JIRA (your clone of REQ-1) should be updated, and descoped items should be identified and reported to the project management team/TSC.
      • API DOCUMENTATION - The Use Case Teams have identified the basic changes for their API that they will be introducing and have started to document that API changes that are associated with their use case. The APIs need to be documented and available in the Use Case Wiki. API freeze is in M3.
      • VNF REQUIREMENTS - Base set of impacts to VNF Requirements identified by use case/ project. The VNF requirements project documents requirements for both PNF and VNFs. Requirements updates should be coordinated with the VNF-REQTS project.
      • DATA MODEL DEVELOPMENT - Discussion of the Data model by Use Case/requirements team with input from the Modeling sub-committee. The modeling sub-committee will communicate the clean release information model as a refining input to the development of the data model for use by the Use Case Teams on specific projects.
      • DATA MODEL REVIEW - Reviews of Data Model with Project (Use Case) Teams. The Data Model is being reviewed by the Use Case Teams with inputs from the Modeling S/C by bringing the developing data model (in the discussion state) to the modeling S/C. It would not be feasible to for the members of the modeling S/C to attend all of the various U/C meetings; although one-off sync-ups might occur in this stage. For those U/C that have significant data modeling work, it would be advised that that U/C team reserves a slot in the modeling S/C meeting(s) to present their data modeling changes and information flows so that the modeling S/C team can advise the U/C team as they develop their data model.
      • MAPPING INFORMATION & DATA MODEL - Mapping of information model and the data model is also done between the modeling S/C and the Use case teams. This might happen in the project teams, or on the modeling S/C calls. Active discussion and interaction between Use Case Team and the Modeling S/C to make sure that the information model and the data model development are in lock-step.
      • CROSS REFERENCING JIRA TICKETS - The modeling S/C uses Jira tickets to track activities; and the Use Case teams also use Jiras to track platform work, modeling work, epics & stories. So it would be smart to link or associate relevant Jira tickets together.
      • JOINT REVIEWS - The Data model should be reviewed with the Modeling S/C. Data model being developed by the component team is using the component model as input.
      • VENDOR EQUIPMENT - If there is any vendor equipment that needs to be delivered it will be sent in this time frame.
    • MODELING SUBCOMMITTEE ENGAGEMENT -
    • For the RELEASE Information Model these are the activities that the Modeling sub-committee is engaged in leading up to M2.
      • RELEASE INFORMATION MODEL (Starting Point) - The release starts with a clean release information model from the PREVIOUS release (with all of its attendant contributions). Then new contributions of the current release are considered (see below the process for handling each specific contribution).
      • DELAYED ELEMENTS OF THE RELEASE INFO-MODEL - Any delayed elements (parameters/classes) in a contribution can't make the current release (it stays experimental), what would happen to the overall contribution or release information model (is it allowed to go clean).
      • INFORMATION MODEL FREEZE - The aggregate / release information model for the release is approved by association with the fragment/ component reviews.  Each of the fragment (contributions) are individually approved.
      • RELEASE INFO MODEL DECLARED CLEAN - After component reviews have concluded and release info model freeze by the modeling S/C the info model is called the "clean model" in M2. The Use Case teams developing Data Models can be certain that the information model will be usable as shown. The diagrams and model wiki pages will indicate that this is a clean model. Put into the information model for that release. Unfinished contributions are postponed.
    • DISCUSSION OF CONTRIBUTIONS - Each contribution discussed according to following process. This is where refining of each of the contribution models occurs by the Modeling Sub-committee (S/C). The release information model is not separately tracked, composed, updated, or released in this period of time. But, rather, each individual contribution has its own Wiki. Thus, for each contribution:
      • CONSIDER CONTRIBUTION - START: Input Contribution (verb Consider) END: Contribution in Discussion State
        • An individual model contribution is a model that will eventually be a part of the total release information model. It is generally a self-contained model which depicts a particular capability or function of the system. This contribution starts as a "input contribution" and undergoes consideration by the modeling sub-committee. Consideration means that the modeling S/C is entertains & assesses if the input contribution should be accepted into the current (or a future release) by weighing the contribution against its relevance and the available resources (modelers) in the release.
      • REVIEW & REFINE CONTRIBUTION - START: Contribution in Discussion State (verb Reviewing & Refine) END: Contribution in Discussion state
        • The contribution undergoes reviewing & refining during the discussion state. Reviewing & refining means that the modeling S/C is discussing the modeling, and updating the contribution based on feedback and comments from the modeling team. Each contribution can be reviewed and refined independently and concurrently with other contributions. Discussion state classes, attributes and relationships are tagged IISOMI experimental.
      • FINAL CALL FOR COMMENTS & INITIATE POLLING - START: Contribution in Discussion State (verb Approving/Poll) END: Contribution in Discussion state
        • (a) FINAL PRESENTATION - The contribution undergo the approval process, and brought one to the modeling S/C for discussion and socialization.
        • (b) FINAL CALL FOR COMMENTS - After that, a final call for comments is issued by a sub-team lead to the modeling team whereby final thoughts & input can be given. This final call for comments signals that the discussion is wrapping up for this contribution and will soon go to a poll.
        • (c) INITIATING POLL - After final call and no further outstanding comments exist, the contribution is brought to a poll by a sub-committee chair. A poll is created whereby modeling S/C members can give the contribution a vote of "yes" or "no". 
      • APPROVING CONTRIBUTION - START: Contribution in Discussion State Post-Poll (verb Approving) Contribution in Clean State
        • After the poll has concluded, the contribution has finished the approval process. The contribution is now considered to be in the clean state. The items that are in the IISOMI experimental state get promoted to a preliminary state. A gendoc is generated and put on the wiki page. The gendoc would be translated and published on the readthedocs site.  
      • STEREOTYPE CHECK - The entities in the model has an experimental stereotype (down to the attribute level) when they are a proposal, when approved/clean, all of the entities in that proposal bear change from experimental to preliminary. Stereotypes can be on classes, attributes, data types and relationships. It is an ISOMII add into the model, at a high-level in the model things get stereotypes. E.g. when we approved the first VES model, which has many entities and many attributes; to update all of those from experimental to preliminary was tough. A stereotype is a status marker. Preliminary is approved for development.

  • Architecture Engagement -
    • M2 ARCHITECTURE WORK - Before M2, the architecture team is working to refine their four basic things: (1) Functional Architecture, (2) Use case impacts (3) component architecture, (4) Architecture enhancements. At M2, the project teams working requirements and use cases should be aware of the reviews for the major architecture initiatives and be involved in reviews.
    • SYNC UP - The architecture sub-committee should have a sync up with the project teams to have a check-point to share updates to the project impacts.
  • Components (PTL) Engagement - ONAP Platform Teams (A&AI, SO, SDC etc) revflease.
    • FEEDBACK - The platform PTLs should be updated and be involved with project teams requirements freezing and discuss if there are de-scoping that may be necessary. API impacts from projects should also be communicated to the project PTLs.
    • SOCIALIZATION - The socialization of project scope changes, and API updates should be made. Attendance at Project PTL meetings will help keep the project teams in sync with the project.


#@#


  • M3 API FREEZE

    • Use Case Engagement -
      • API Freeze - M3 is characterized by the API freeze. The main thing that happens at M3, the API is frozen by the Use Case Teams.
      • Data Model Freeze - Developers identify a problem in the data model which affects the information model.
        • SYNC UP - since the Modeling S/C is familiar with the info-model; the Use Case Teams should present at the Modeling S/C their proposed data model that might be frozen so that the modeling S/C can assess it to see if might have impact to the Info-model. There should be some collaboration or check-point at M3 to discuss and potential ripple affects back to the information model.
        • DATA MODEL IMPACTING INFO MODEL - If changes in the Data Model impact the information model, those changes need to be worked by the model S/C. The Modeling S/C would evaluate the change to the Information model and possibly make updates.
        • USE CASE TEAMS INDICATE CHANGE - The Use Case teams may have enough knowledge of the info-model that they identify a data model change that may impact the information model. This presumes that the use case teams know that their changes in a data model may have impact to the information model.B
        • CONSIDER DATA MODEL - START: Input Data Model > verb Consider > END: Data Model in Discussion State
          • The data model is a model that is used in a Use Case and is based on the Information Model. It is generally a self-contained model which depicts a particular capability or function of the system. The data model starts as a "input data model" and undergoes consideration by the Use Case teams. Consideration means that the Use Case teams is entertains & assesses if the input data model. If the Use Case teams think that the contribution is not ready for the current release that contribution it might postponed. It would be noted in the Release Management Project page as such.
        • REVIEW & REFINE CONTRIBUTION - START: Data Model in Discussion State > verb Reviewing & Refine > END: Data Model in Discussion state
          • The data model undergoes reviewing & refining during the discussion state. Reviewing & refining means that the Use Case Teams are discussing the data model and updating their data model based on feedback and comments from the Use Case team and modeling team. Each data model can be reviewed and refined independently and concurrently with other use case projects. Things in the discussion state are classes, attributes and relationships are tagged as IISOMI experimental.
        • MODELING S/C ENGAGEMENT - The Use Case teams may wish to solicit the opinion of the modeling S/C and present their data model for discussion and socialization.
        • FINAL CALL FOR COMMENTS & INITIATE POLLING - START: Data Model in Discussion State > verb Approving/Poll > END: Data Model in Discussion state
          • (a) FINAL PRESENTATION - When the data model has gotten to a point where the use case team feels that it can start to undergo the approval process, the data model is brought one final time the use case team.
          • (b) FINAL CALL FOR COMMENTS - After that, a final call for comments is issued by a use case lead to the modeling team whereby final thoughts & input can be given. This final call for comments signals that the discussion is wrapping up for this contribution and will soon go to a poll.
          • (c) INITIATING POLL - After final call and no further outstanding comments exist, the contribution is brought to a poll by a use case lead. A poll is created whereby use case team members can give the contribution a vote of "yes" or "no". 
        • APPROVING CONTRIBUTION - START: Data model is in Discussion State Post-Poll > verb Approving > Data model in Clean State
          • After the poll has concluded, the data model has finished the approval process. The data model is now considered to be in the clean state. The items that are in the IISOMI experimental state get promoted to a preliminary state. A gendoc is generated and put on the wiki page. The gendoc would be translated and published on the readthedocs site.  #@# do data models also use ISOMII states?
      • Component Data Model Final - x.
      • RECONCILE - Reconciling the info-model with the data-model. M3 checklist. (API Freeze)
      • M3 CHECKLIST - The M3 check list is used. This is a vehicle to engage the Use Case (project teams) and reconcile the Use Case Teams with the modeling S/C team's work. The Check list can be found here: Proposed M3 Checklist modeling updates discussion
    • M3 MODELING SUBCOMMITTEE ACTIVITIES -
      • REFINEMENTS TO THE RELEASE INFO MODEL - The Release Information Model is clean at M3. It is considered "base-lined" and "final", hence it is marked clean. Though, updates can still happen to the release information model and the model contributions therein. This means that certain elements within the model(s) could go to back to an experimental state. Note that only certain elements (e.g. attributes, ranges) are likely to go to the experimental state NOT the entire contribution. More often though, new additions could be added to a contribution model. In general, there would likely be just minor tweaks on the model. So when a contribution is clean it has to be at least preliminary. A contribution cannot be clean and experimental. Clean has a relationship to the IISOMI states. For an entity to be clean it must be either preliminary or mature (see the IISOMI state diagram link).
        • IISOMI STATES - A link to the IISOMI state diagram can be found here: Stereotypes 
        • NEW ADDITIONS - A contribution model could be clean, but things added afterwards and those elements would come in as experimental. 
      • STILL IN PROGRESS ITEMS IN RELEASE INFO MODEL - It is possible that as the modeling team enters the M3 milestone that there are still some things in progress, that are expected to be in the current release. They might still be marked experimental even though the release information model is clean. Thus, to open item are continue to be work; and it is expected it would not affect software if code were already associated to it.
        • ITEMS IN DISCUSSION - e.g. when root contribution was done, with root party is an example as it was not agreed to, we made the decision to leave that experimental until a future date. There were aspects agreed, and other things left experimental to pursue in the future. The main contribution was split. These parts everyone agreed with and these part left experimental which would be taken up in a future contribution and re-discussed. This would likely occur at M2, and they might be discussed at M3. There was a conscious decision and agreement by the modeling team that the parts of the model still open would be pushed to the next release. So only theoretical discussion would happen at this point of how to proceed in the future release.
        • FUTURE WORK - Things originally planned to be in a release could potentially transform into future work items. Some modeling work could be pushed to the next release if need be, if it is decided that it could not be completed in the current release.
      • FUTURE WORK - Future work is typically identified as such at the start of a release at M0 in the release modeling planning page. Future Work can still proceed. For example, in R6 the geo-location modeling work is not tied to any active development yet. The location work is a good example of work that was worked in ADVANCE of when it is expected to be used (Future Work). It is also possible that some of the future work is building upon a foundation of work that had already been started (or was looked at) or implemented in a prior release.
        • DEFER WORK - It might be decided the the future work could be deferred to the next release. On the current modeling high level requirements page to indicate that a particular future work has been deferred to a future release. In order not to lose the activity, it would be expected that it would be rolled into the next release's Modeling High-Level Requirements.
        • CONTINUE WORK - Future Model work may continue to proceed in the current release..
      • DOCUMENTATION AFTER IMPLEMENTATION IN PRIOR RELEASE WORK - This type of work is the model is catching up to already implemented software. It has already been identified as something that would be worked on for that release at M0. It is expected that it wouldn't immediately impact the current software. However, it may be extended eventually to incorporate new work. The way to proceed with this category of work is handled the same way as the future work (i.e. Defer or to Continue the work) given modeling improvement recommendations on how better to model a given concept.
      • M3 CHECKLIST - The M3 check list modeling updates discussion is used by the modeling sub-committee. It is used as a vehicle to engage the Use Case (project teams) and reconcile the Use Case Teams with the modeling S/C team's work. See also the Use Case Team Engagement (section below). The Check list can be found here: Proposed M3 Checklist modeling updates discussion

    • READ THE DOCS - (M3 or M4?) The model editor provides a final gendoc word document which serves as the basis for what will be incorporated into the readthedocs. The read the docs can be found here: https://onap.readthedocs.io/en/latest/index.html . The word document is fed into some tools which generates the readthedocs output. The gerrit master model is periodically updated, and a snapshot of the eclipse/papryus model is taken and that is called the release model.
    • DOCUMENT GENERATION - The RST documentation that only contains things in the current release or everything that is approved.
    • PAPYRUS GENERATION - The Papyrus snapshot is generated. The RST document is created. The readthedocs documentation is generated.
