Figure 42. Build Functions Model

Description

The Build functions (formerly Requirement to Deploy) enable the creation, enhancement, and maintenance of Digital Products throughout their entire lifecycle: planning the work, designing, developing (or configuring), testing, and releasing a new Product Release. The Build functions support the creation and sourcing of new, or the modification of existing, Digital Products. This includes the product engineering of all types of products, such as the development of custom-built software, the development of cloud-native applications, the configuration of package-based software (COTS) or SaaS, as well as the development of infrastructure products (or platforms) which can be used to host other Digital Products.

This function includes the development of the initial Product Release (e.g., an MVP release) as well as fulfilling new (or modified) requirements and features, improving user experience, performing maintenance activities (such as fixing Defects and Problems), and ensuring the product remains compliant with policies and non-functional requirements (including security, risk, and regulatory requirements), etc.

The Build functions contain the following functional components:

  • Develop functionality:

    • Product Backlog component

    • Requirement component

    • Product Design component

    • Source Control component

    • Pipeline component

    • Build Package component

    • Release Composition component

  • Test functionality:

    • Test component

    • Defect component

The Build functions are process-agnostic; while methods and processes may change (i.e., SCRUM for Agile development, Kanban, Project Management methods, Test-Driven Development (TDD), etc.), the functional components and data objects that comprise the Build functions remain constant.

The Build functions provide the framework for creating and sourcing new, or modifying existing, applications or products. This function maintains a Product Backlog which can receive demand signals from a consumer (e.g., new features or business requirements), or from other components such as Portfolio Backlog Management, Policy Management, and Problem Management. This may take the form of an approved Portfolio Backlog Item from the Plan functions, or may be a smaller-grained signal such as an individual feature, user story, Defect, or Problem. The Build functions deliver the Product Release (for a new or modified product), which is packaged for immediate or future deployment through the Deploy value stream.

Related Value Streams

The following value streams use one or more functional components from the Build functions:

  • Integrate

  • Release

  • Deploy

Business Benefits

The Build functions describe a prescriptive framework of required functional components, integrations and data objects so organizations can deliver better value, sooner, safer with lower costs while improving the happiness and productivity of the product teams.

The key benefits of using the Build functions are:

  • Reduce lead time of delivering Product Backlog Items (e.g., new features or resolving Defects or Problems)

  • Ensure predictable, cost-effective, and high-quality products delivered to consumers

  • Increase the deployment frequency of delivering new Product Releases

  • Increased change success rate (and reduce issues introduced with the new Product Release)

  • Improved code quality and reduced security risks (and vulnerabilities)

  • Provide end-to-end transparency and traceability from a new requirement and/or backlog item to the delivery of a new release

  • Increased management information for benchmarking of internal and external service developers and suppliers

  • Reduced risks, as products are designed in accordance with standards and policies (from sources including Security Management, Governance, Risk, & Compliance, Legal & Regulatory, Enterprise Architecture, Financial Management, and so on)

  • Provide full transparency of the value delivered per release, as well as tracking the cost associated with the development of new features

  • Provide insight into time spent on new feature development versus time spent on eliminating technical debt and/or resolving Defects

  • Make service delivery predictable, even across geographically dispersed teams, multiple suppliers, and multiple development methodologies

  • Improve collaboration between involved stakeholders and teams (including external vendors)

    Applications and services are now sourced or developed in cooperation with many different parties, all of whom work with their own processes and tooling. Digital organizations must be able to provide a good overview of the planned activities, speak a common language with all parties involved, and provide a methodology for how to achieve the highest quality results. Cloud sourcing, Agile development, and other innovations have created the need for enterprises to be able to manage development and delivery of services in a hybrid or multi-sourced environment.

  • Ensure that products are developed in line with policies, e.g., secure by design

  • Ensure that each Product Release is high quality, fit-for-purpose, and meets customer expectations

    Organizations delivering Digital Products and services still experience too many incidents immediately after an application or service is released into production. Organizations must establish control over the quality of a service regardless of the number of vendors involved in development and/or delivery.

  • Standardize product development and delivery to the point where the re-use of service components is the norm

    Operations in the development of Digital Products must ensure increased quality and speed of service delivery, while also lowering costs. In support of these efficiency and quality goals, organizations must have a framework in which to drive the re-use of existing service components at multiple stages of the development lifecycle across multiple applications and services. They must work successfully with multiple internal and external contributors and be able to integrate the data, process, and tools required to work with geographically dispersed teams, outsourcers, and traditional and cloud-based suppliers. Furthermore, organizations must maintain control of the governance of the Build functions and be able to track and measure internal and vendor performance, costs, quality, and on-time delivery. The abilities to re-use Requirements, source code, documentation, test scripts, Service Monitors, and other artifacts of a service development lifecycle are key contributors to managing costs, increasing quality and predictability, and accelerating release cycles.

  • Reduce number of Incidents occurred in production caused by the new release (better product quality)

  • Improved availability, performance, and resilience of the product in production due to better designs, architecture, and ensuring non-functional requirements are integrated into the overall Product Design

  • Accelerate the sourcing and delivery of products and services through best practices such as:

    • Re-use – manage, maintain, and leverage re-usable components and services

    • Automation – identify the core functional components and data required to streamline the Integrate value stream

    • Collaboration – use data to institutionalize collaboration of teams involved in the development lifecycle

7.1. Develop Function

The Develop functionality is centered around the development, enhancement, and maintenance of Digital Products.

7.1.1. Product Backlog Functional Component

id EAID 748C0139 E2B2 45e1 AD28 6CE5E65C0CD1
Figure 43. Product Backlog Functional Component Model

Purpose

The Product Backlog functional component manages the lifecycle of all work items (Product Backlog Items) involved in designing and delivering new releases (or updates) of a product. Each Product Backlog is associated with a Product Manager and one or more teams (for example, an Agile or DevOps team); multiple teams building a single Digital Product work from a single Product Backlog that defines all of the work to be done. A product, however, can be decomposed into sub-products (or components) each having their own related Product Backlog and associated teams.

The Product Backlog is the single authoritative source for all work items (referred to as Product Backlog Items) that teams work on to achieve the outcome. The Product Backlog lists all features, stories, story tasks, enhancements, and fixes that constitute the changes to be made to the product in future releases. A Product Backlog Item can be decomposed into sub-Product Backlog Items. For example, a feature can be decomposed into user stories and related tasks. A subset of the Product Backlog Items can be assigned to an iteration or sprint backlog.

The Product Backlog functional component coordinates the creation and provides ongoing execution oversight of backlog items aimed at creating or modifying a product, together with associated deliverables such as training materials and user guides. The Product Backlog aggregates, tracks, and reports status, resources consumed against the plan (e.g., iteration or sprint plan), and communicates these to stakeholders. The Product Backlog governs, coordinates, influences, and directs initiative execution, as well as ensuring financial goals and boundary conditions are adhered to. The Product Backlog functional component maintains the linkage/traceability from Portfolio Backlog Items to Product Release.

The Product Backlog also receives Defects from the Defect functional component to enable the development of fixes and/or temporary work-arounds.

The Product Backlog functional component supports the value streams:

7.1.2. Requirement Functional Component

id EAID 168DEA01 781C 45e8 847A F23B668B0EED
Figure 44. Requirement Functional Component Model

Purpose

The Requirement functional component manages the Requirements of a product throughout its lifecycle. Requirements are associated with the Product Backlog Items managed in the Product Backlog. The Product Backlog manages all epics, features, and stories, which are short-lived, and closed once completed, while the Requirements are long-lived and provide the definitive specifications of the product. This definitive list of Requirements is also used for regression testing.

Note
The Requirement functional component also tracks non-functional requirements, such as those related to security, risk, privacy, and compliance. These non-functional requirements are derived from the Policy functional component and are selected based upon the outcome of risk assessments. For example, based upon the BIA, Security Impact Assessment (SIA), Threat and Vulnerability Assessment (TVA), and Data Privacy Impact Assessment (DPIA), the relevant security and compliance Requirements should be added to the Requirement functional component. These Requirements are then linked to the Product Design, Product Backlog Items, and associated Test Cases. This ensures the product is designed according to the agreed Policies and enables full traceability on the compliance of the product against defined Policies and controls.

The Requirement functional component manages all the Requirements (both functional and non-functional requirements) for the different stakeholders such as those related to:

  • Business requirements

  • Security requirements (derived from Policies)

  • Requirements derived from SLOs such as those related to availability, performance, and capacity (to define the expected performance of the product)

  • Legal, regulatory, and compliance requirements (such as those related to data privacy)

  • Data management requirements

  • Continuity/disaster recovery requirements (related to business and service continuity)

  • Architectural requirements

  • User experience requirements (such as those related to XLAs)

  • Operations requirements (such as those related to monitoring and logging)

The Requirements need to be collected, refined, scoped, and have their progress tracked across the different sprints and releases.

7.1.3. Product Design Functional Component

id EAID 0B0D15C4 E832 4cfc 8607 0DDC27CDFFC3
Figure 45. Product Design Functional Component Model

Purpose

The Product Design functional component creates and maintains the Product Design associated with a Digital Product. This functional component ensures the architecture and Product Design of the Digital Product meets specified requirements, is in line with the Enterprise Architecture, and adheres to standards and polices.

The Product Design functional component describes the structure and behavior of the services offered by the product, taking into consideration both the desired product and the associated Service Offers. Various design artifacts (e.g., UML® diagrams, API specifications, data models, process designs, user experience design, etc.) can be created that comply with the Product Backlog Item specifications, Requirements, and product vision. The service delivery model (in-source, outsource, etc.) can be identified, together with the service providers who will meet the Requirements within the chosen delivery model.

It is important to ensure that the product architecture and Product Design are compliant with all policies and standards, including security standards and architectural guidelines; this helps to ensure the confidentiality, integrity, and availability of the service, as well as to ensure “Secure by Design” and “Privacy by Design”.

It is also useful to put instrumentation in place so that empirical data can be captured on how the digital services are performing rather than relying only on anecdotal input from the user community. The service should also be architected so that it can meet the KPIs and SLAs (and associated SLOs). The output of the Product Design functional component will be used by the Source data object to source, create, and secure the service, and the traceability will be done through the Requirement functional component.

The Product Design functional component supports the value streams:

  • Shall document how the Digital Product complies with the non-functional requirements, including security, privacy, legal, etc. (Secure, Privacy, and Compliance by Design)

  • Shall document how the product is architected to meet the SLOs, including availability and performance, as well as Experience-Level Agreements (XLAs)

  • Shall receive the Digital Product specifications and product vision from the Product Portfolio functional component

  • Shall provide the ability to collaborate on the design artifacts, including reviews, capturing feedback, and comments

7.1.3.1. Product Design Data Object

Purpose

The Product Design data object is the collection of design artifacts related to a Digital Product, together with the changes to the Product Design for a specific Product Release. It represents the grouping of logical components necessary to provide the expected outcome or service interaction.

7.1.4. Source Control Functional Component

id EAID 08B37A82 5FE6 4c69 8995 597440EDDDBF
Figure 46. Source Control Functional Component Model

Purpose

The Source Control functional component develops and manages all the source code (and tracks all changes to the source) for a Digital Product. It is the system of record for all sources and configuration changes which fall under version control. The Source Control functional component ensures that access and updates to the source code are securely controlled.

In this context, “Source” also includes code that captures changes and configurations made to package-based software and SaaS applications; for example, configuring or customizing standard packages such as modifying business rules and workflows, configuring APIs, database configuration, etc. The Source Control functional component additionally manages the source code related to infrastructure (referred to as infrastructure as code).

Since all modifications in the source code repository are under change and version control, any source code changes need to be traced back to associated Product Backlog Items. As part of product development, various other automation routines are created such as test scripts, deployment templates, or workflows and monitors (e.g., monitoring as code). These automation scripts are also maintained by the Source Control functional component.

The Source Control functional component supports the Integrate value stream.

Functional Criteria

The Source Control functional component:

  • Shall be the system of record (authoritative source) for all Sources

  • Shall associate the source code repository to the Digital Product (owning the Source)

  • Shall implement the necessary security controls to protect and manage access to source code

  • Shall manage the lifecycle of the Source

  • Shall ensure Source updates are traced back to one or more Product Backlog Items (they understand the origin of changes)

7.1.5. Pipeline Functional Component

id EAID 3CE031DE FDF7 4911 A39A 3B75F0992758
Figure 47. Pipeline Functional Component Model

Purpose

The Pipeline functional component orchestrates the activities needed to deliver a tested, validated, and compliant Product Release. Its purpose is to orchestrate and coordinate the tasks associated with building, verifying, testing, and deploying software changes, and the Pipeline functional component can manage different types of Pipelines, such as:

  • Continuous Integration or build Pipelines

  • Release Pipelines orchestrating the release across the different environments (such as test, acceptance, and production)

A Pipeline defines an orchestration workflow consisting of several steps (jobs or tasks) and stages to be performed, including:

  • Execute build activities and create the Build Package (compiling and packaging) triggered by code changes

  • Initiate code quality checks (executed by the Test functional component)

  • Trigger the execution of Test Plans such as those related to unit testing, functional testing, and performance and security testing

  • Initiate deployments to different environments such as test, stage/acceptance, and production (via the Order functional component)

  • Validate the outcome of build, test, and deployment activities against agreed controls and policies

The Pipeline controls the movement of code from a commit in the Source Control functional component, through its development via the different environments such as test, acceptance, and production. The Pipeline functional component triggers the Fulfillment Orchestration functional component to perform the actual deployment. A Pipeline also embeds the required controls to ensure releases are processed through the Pipeline in a secure and compliant manner. The configuration of a Pipeline should be managed as code and placed under version control.

The Pipeline functional component supports the Integrate value stream.

Functional Criteria

The Pipeline functional component:

  • Shall ensure that the Pipeline is under version control and secured (for unauthorized changes)

  • May manage the Pipeline as code in the Source Control functional component

  • Shall associate the Pipeline to the source code repository (e.g., a merge request can initiate the Pipeline to execute build activities)

  • Shall manage the executions of the Pipelines (and keep track of all activities and outcomes)

  • Can associate the Pipeline to a Digital Product

  • Shall ensure that policies are embedded into the Pipeline so that security, risk, and compliance checks are executed as part of build and release activities

  • Shall track the progress and status of the Pipeline activities/tasks (a Pipeline consists of one or more tasks)

  • Shall associate a Pipeline to one or many Test Plans which are initiated as part of the Pipeline workflow

  • Shall register the Build Package in the Build Package functional component

  • Shall trigger the execution of one or more Test Plans

  • Shall update the status of the associated Product Release based upon the outcome of the deployment and activities across the different environments

  • Shall create a Change to log the planned and executed deployment of a Product Release

  • Shall create a Change to inform stakeholders about the (planned) Change

  • Shall use the Change functional component to perform a change impact assessment and determine potential conflicts (identifying potential conflicts of multiple changes)

  • Can use the Change functional component to schedule the actual deployment in the appropriate change window (e.g., in case a deployment results into downtime)

  • Shall wait for the approval of the Change functional component to continue with the workflow of the Pipeline

  • Shall initiate the deployment of the Product Release through the Fulfillment Orchestration functional component (e.g., to a test, acceptance, or production environment)

7.1.5.1. Pipeline Data Object

Purpose

The Pipeline data object defines and controls the execution of all the activities (and stages) to orchestrate and validate the build, and the deployment and testing activities required to securely deliver a modified Product Release.

Key Attributes

The Pipeline data object shall have the following key data attributes:

  • Id: unique identifier of the Pipeline

  • Name: name of the Pipeline

  • Version: version of the Pipeline

Key Data Object Relationships

The Pipeline data object shall maintain the following relationships:

id EAID 83398404 7DF5 4df9 B09B 3B09E58851F4
Figure 51. Defect Functional Component Model

Purpose

The Defect functional component keeps track of all Defects; including their origin, status, importance, and relation to Requirements and Problems (or known errors). Defects of all types are registered (including security-related Defects), together with all relevant details such as description, severity, product version, related requirement, etc. Defects can be analyzed, and resolutions found. Defects can be associated with Requirements.

Note
A Defect in this context is not just a bug (not meeting a specified requirement) but can be any issue that impacts the product in delivering the expected value and outcome for the consumer, such as poor user experience, potential vulnerabilities, maintainability issues, technology debt, etc.

The Defect functional component documents issues that should be communicated to the Release Composition functional component. The Defect functional component consumes Defects from the Problem functional component and the Test functional component, and these are in turn consumed by the Source Control functional component for review and resolution. Defect details can be updated, and used to decide on target release times. The Defect status can be monitored, and Defect reports provided. Defects that remain unresolved by service development can be converted to known errors for Problem Management to document, develop work-arounds for, and/or report in Knowledge Management articles.
