Business Analysis Quarter

Business Analysis Quarter (hereinafter, the Quarter) is the second of four lectures of Project Quadrivium (hereinafter, the Quadrivium):

• The Quarter is designed to introduce its learners to enterprise analysis, or, in other words, to concepts related to analyzing enterprise data in order to create enterprise information or, in other words, information needed for enterprise design; and
• The Quadrivium examines concepts of administering various types of enterprises known as enterprise administration as a whole.

The Quadrivium is the first of seven modules of Septem Artes Administrativi, which is a course designed to introduce its learners to general concepts in business administration, management, and organizational behavior.

Lecture outline

The predecessor lecture is Data Gathering Quarter.

Concepts

1. Business analysis. The set of tasks and techniques used to work as a liaison among stakeholders in order to understand the structure, policies and operations of an organization, and recommend solutions that enable the organization to achieve its goals.
   • Business need. A type of high-level business requirement that is a statement of a business objective, or an impact the solution should have on its environment.
2. Requirement. (1) A condition or capability needed by a stakeholder to solve a problem or achieve an objective; (2) A condition or capability that must be met of possessed by a solution or solution component to satisfy a contract, standard, specification or other formally imposed documents; (3) A documented representation of a condition or capability as in 1) or 2).
   • Stated requirement. A requirement articulated by a stakeholder that has not been analyzed, verified, or validated. Stated requirements frequently reflect the desires of a stakeholder rather than the actual need.
3. Business requirement. A higher level business rationale that, when addressed, will permit the organization to increase revenue, avoid costs, improve service, or meet regulatory requirements.
   • Stakeholder requirement. Stakeholder requirements are statements of the needs of a particular stakeholder or class of stakeholders. They describe the needs that a given stakeholder has and how that stakeholder will interact with a solution. Stakeholder requirements serve as a bridge between business requirements and the various categories of solution requirements.
   • Business requirements document. A requirements package that describes business requirements and stakeholder requirements (it documents requirements of interest to the business, rather than documenting business requirements).
4. Solution requirement. A characteristic of a solution that meets the business and stakeholder requirements. May be subdivided into functional and non-functional requirements.
   • Functional requirement(s). The product capabilities, or things the product must do for its users.
   • Non-functional requirement(s). The quality attributes, design and implementation constraints, and external interfaces that the product must have.
   • Quality attribute. The subset of nonfunctional requirements that describes properties of the software's operation, development, and deployment (e.g., performance, security, usability, portability, and testability).
   • Transition requirement(s). A classification of requirements that describe capabilities that the solution must have in order to facilitate transition from the current state of the enterprise to the desired future state, but that will not be needed once that transition is complete.
   • Design constraint. A solution requirement that limit the options available to the system designer.
   • Systems requirements specification. A requirements document written primarily for Implementation SMEs describing functional and nonfunctional requirements.
5. Requirements model. A representation of requirements using text and diagrams. Requirements models can also be called user requirements models or analysis models and can supplement textual requirements specifications.
   • Requirement attribute. Metadata related to a requirement used to assist with requirements development and management.
   • Requirement defect. An error in requirements caused by incorrect, incomplete, missing, or conflicting requirements.
   • Requirements allocation. The process of apportioning requirements to subsystems and components (i.e., people, hardware, and software).
   • Requirements traceability. The ability to identify and document the lineage of each requirement, including its derivation (backward traceability), its allocation (forward traceability), and its relationship to other requirements.
6. User requirements document. A requirements document written for a user audience, describing user requirements and the impact of the anticipated changes on the users.
   • Requirements package. A requirements package is a set of requirements grouped together in a document or presentation for communication to stakeholders.
   • Baseline. A point-in-time view of requirements that have been reviewed and agreed upon to serve as a basis for further development.
   • User story. A high-level, informal, short description of a solution capability that provides value to a stakeholder. A user story is typically one or two sentences long and provides the minimum information necessary to allow a developer to estimate the work required to implement it.
7. Use case. An analysis model that describes the tasks that the system will perform for actors and the goals that the system achieves for those actors along the way.
   • Included use case. A use case composed of a common set of steps used by multiple use cases.
   • Use case diagram. A type of diagram defined by UML that captures all actors and use cases involved with a system or product.
   • Work product. A document or collection of notes or diagrams used by the business analyst during the requirements development process.
8. Verified requirement. Requirements that have been shown to demonstrate the characteristics of requirements quality and as such are cohesive, complete, consistent, correct, feasible, modifiable, unambiguous, and testable.
   • Verification. The process of checking that a deliverable produced at a given stage of development satisfies the conditions or specifications of the previous stage. Verification ensures that you built the solution correctly. Also see requirements verification.
   • Requirements verification. The work done to evaluate requirements to ensure they are defined correctly and are at an acceptable level of quality. It ensures the requirements are sufficiently defined and structured so that the solution development team can use them in the design, development and implementation of the solution.
9. Validated requirement. A requirement that has been demonstrated to deliver business value and to support the business goals and objectives.
   • Validation. The process of checking a product to ensure that it satisfies its intended use and conforms to its requirements. Validation ensures that you built the correct solution. Also see requirements validation.
   • Requirements validation. The work done to ensure that the stated requirements support and are aligned with the goals and objectives of the business.
   • Requirements signoff. Formal approval of a set of requirements by a sponsor or other decision maker.
10. Requirements iteration. An iteration that defines requirements for a subset of the solution scope. For example, an iteration of requirements would include identifying a part of the overall product scope to focus upon, identifying requirements sources for that portion of the product, analyzing stakeholders and planning how to elicit requirements from them, conducting elicitation techniques, documenting the requirements, and validating the requirements.
    • Iteration. A process in which a deliverable (or the solution overall) is progressively elaborated upon. Each iteration is a self-contained "mini-project" in which a set of activities are undertaken, resulting in the development of a subset of project deliverables. For each iteration, the team plans its work, does the work, and checks it for quality and completeness. (Iterations can occur within other iterations as well. For example, an iteration of requirements development would include elicitation, analysis, specification, and validation activities.)

Roles

1. Analyst. A generic name for a role with the responsibilities of developing and managing requirements. Other names include business analyst, business integrator, requirements analyst, requirements engineer, and systems analyst.
   • Business analyst. A practitioner of business analysis.
2. User. A stakeholder, person, device, or system that directly or indirectly accesses a system.
   • End user. A person or system that directly interacts with the solution. End users can be humans who interface with the system, or systems that send or receive data files to or from the system.
3. Actor(s). The human and nonhuman roles that interact with the system.
   • Secondary actor. An actor who participates in but does not initiate a use case.
4. Product stakeholder. A group or person who has interests that may be affected by an initiative or influence over it.
   • Supplier. A stakeholder who provides products or services to an organization.
   • Sponsor. A stakeholder who authorizes or legitimizes the product development effort by contracting for or paying for the project.
   • Customer. A stakeholder who uses products or services delivered by an organization.

Methods

1. Peer review. A validation technique in which a small group of stakeholders evaluates a portion of a work product to find errors to improve its quality.
   • Walkthrough. A type of peer review in which participants present, discuss, and step through a work product to find errors. Walkthroughs of requirements documentation are used to verify the correctness of requirements. See also structured walkthrough.
2. Gap analysis. A comparison of the current state and desired future state of an organization in order to identify differences that need to be addressed.

Instruments

1. Requirements management tool. A software tool that stores requirements information in a database, captures requirements attributes and associations, and facilitates requirements reporting.
2. Requirements trace matrix. A matrix used to track requirements' relationships. Each column in the matrix provides requirements information and associated project or software development components.
