1. Roadmap and Feature Planning
Purpose
- To create the initial time-line for the release: the roadmap.
- To define/update the platform functional requirement.
- To identify the main technical goals for the new release.
Entry Criteria
- E1-1 Previous release version of the distribution was released.
Tasks
- T1-1 Create the roadmap and platform functional requirement specification.
A detailed description about the rules used to build the roadmap and platform functional requirement is in [xx]. These document need to be written in AGL confluence.
- T1-2 Feature freeze calendar.
Together with the roadmap calendar is the associated feature freeze calendar. There are three stages of freezing: toolchain freeze after M3, base system freeze after M4 and full feature freeze after B1. After that the quality assurance process starts.
- T1-3 Determine the new features.
On the AGL Instrument Cluster Expert Group the new features expected for this release are discussed and defined. As a result new version of the platform functional requirement specification will be released. This spec must be created before architecture development phase.
Verification
- V1-1 Review the platform functional requirement
The platform functional requirement needs to be approved by at least half of the SAT (System Architecture Team) core members and at least half of the SC (Steering comity) members.
- V1-2 Review the roadmap.
The roadmap needs to be approved by the Product Manager(Walt?) and the Instrument Cluster Expert Group Leader(Haraki-san?).
- V1-3 Platform functional requirement and roadmap maintenance.
Small changes in the roadmap are not communicated, just executed. But if a delay threatens the release day, an announcement is expected, and if the delay is serious we need to communicate it widely.
When the platform function is dropped from initial platform functional requirement, it must be approved by at least half of the SAT (System Architecture Team) core members. After that platform functional requirement specification must be update.
Exit Criteria
- X1-1 The platform functional requirement specification and the roadmap calendar are fixed and froze.
Deliverables
- D1-1 The platform functional requirement specification is published in AGL confluence.
- D1-2 The roadmap calendar is published in AGL confluence.
2. Architecture Design
Purpose
- Identify which software requirements are to be allocated to which architectural elements of the software.
- Evaluate the software architectural design against defined criteria.
Entry Criteria
- E2-1 Roadmap and Feature Planning phase was completed.
Tasks
- T2-1 Create/update software architecture block diagram
First step of the architecture design shall create and update software architecture block diagram such as this. Typically, adding/removing architecture blocks is only allowed by adding/removing functional requirements or refactoring. This block diagram need to be written in AGL confluence.
- T2-2 Create/update software component list and component block diagram
The software architecture block diagram shall break down to software component list and component block diagram. Element of software component list shall be linking to platform functional requirement.
Each software component divide to AGL development software and existing opensource software. The process for AGL development software is set out in Section 2.1. The process for reusing existing opensource software is set out in Section 2.1.
2. 1. Architecture Design for the AGL development software
Purpose
- Determine the role of that software component in the AGL instrument cluster software platform.
- Evaluate the software architectural design against defined criteria.
Entry Criteria
- E2.1-1 The extraction of the relevant software components shall be completed.
Tasks
- T2.1-1 Create/update software architecture block diagram
2.2. Architecture Design for the reusing existing opensource software
Purpose
- Determine the role of that software component in the AGL instrument cluster software platform.
Entry Criteria
- E2.2-1 The extraction of the relevant software components shall be completed.
