Chapter 7: Scope Flashcards

Q

C7 Scope: Terms and terminology

A
  • Definition of done (DOD) - применяется к Story, Release и даже Final Product
  • Deconstruction (=decomposition)
  • Product Analysis As a Scope-defining Method - анализируем цели и описание продукта to define tangible deliverables
  • Requirements Traceability Matrix (RTM) - links requirements to objectives (!) and/or other req. Помогает оценивать CRs в т.ч.! Req attributes (IDs, source, status) тоже должны быть либо в ней, либо в отдельном приложении
  • Timeboxing (agile) - временные рамки чего-либо. Для скоупа - строгое ограничение длины итерации. Не успели сделать story? Кладем в backlog для следующих итераций.
  • Minimal Marketing Feature (MMF) (Agile) - smallest feature that can be released into the marketplace
  • Minumally Viable Product (MVP) (Agile) - a version of a product with just enough features to make it useful

Q

Method for Eliciting and Analyzing Requirements

A
  • Verbal methods
    • Brainstorming - собираем не критикуя, а потом оцениваем приоритеты используя Multicriteria Decision Analysis and Nominal Group Technique
    • Interviews - individual/group, phone/email etc.
    • Focus groups - выбираются SH или SME из одной зоны, обсуждают. Conversation directed by a moderator
    • Questionnaires and Surveys
    • Benchmarking - смотрим, что у конкурентов. Может быть долго и дорого
    • Facilitation - собирают разных SH и используют consensus approach чтоб прийти к соглашению Иногда используют Voting
    • Voting
    • Multicriteria Decision analysis - quantify req using decision matrix based on factors like risk / time / cost / benefit
    • Nominal Group Technique - все записывают свои идеи privately, а потом каждый шарит их со всеми (открыто или нет???)
    • Observation - generally shadowing.
    • Prototypes (agile) - показываем SH модель продукта. Может быть несколько стадий
    • User stories - during facilitated discussion sessions SH пишут короткие stories: as a “role” I want “functionality/goal” so that “business benefit”
    • Joint application design (JAD) - еще один способ выявления требований для улучшения процессов при software development
    • Quality functional deployment (QFD) or Voice of the Customer (VOC) - еще один способ выявления и приоритезации требований в области manufacturing
  • Graphic methods
    • Mind Maps (see pic) - way of diagramming ideas to help generate, classify or record info. Branches out of a central core.
    • Context diagram (see pic) (or Context Level Data Flow Diagram) - show the relationship between elements of an environment
    • Affinity (схожесть) Diagrams (see pic) - grouping req by similarities
    • Agile Modeling (? не уверен что в этой секции)
      • Use-case modelling - отдельная карточка
      • Process models
      • Wireframes
      • Low fidelity prototypes - примерная модель, рисуем на доске с клиентом
      • High fidelity prototypes - точная модель

Q

Competing Requirements resolution

A

Best comply with:

  • Business case
  • Proj charter

Q

Scope Statement

A

На входе - выровненные требования

На выходе:

  • Product scope (product deliverables)
  • Project scope
  • List of product deliverables
  • Acceptance criteria
  • Out of scope
  • Assumptions and constraints

Q

WBS / Control account / Planning package / Work package

A

WBS
Start from the name of the project, is decomposed to work packages

Control account
Allows to collectively manage and control cost/sched/scope at a higher level than the work package

Planning package
Located below a control account and above the work packages

Work package

  • are things (deliverables, product) rather than actions (activities).
  • The smallest item in the WBS.
  • Размеры: для small-проектов: 4-40часов, medium: 8-80, big: 300+

Activity list - decomposition of WBS but do not included in WBS! Typically 80 hours max (?)

Q

Methods for Agile Story Decomposition

A

Good story - INVEST:

  • Independent - stories should be as independent as possible.
  • Negotiable - a story is not a contract. A story is an invitation to a conversation.
  • Valuable
  • Estimable
  • Small - stories should be small chunks of work (eg. two week iterations average 3-4 days of work)
  • Testable

Decomposition

  • Process-based breakdown - процессы разбиваем на подпроцессы
  • CRUD (Create, Read, Update, Delete) - в описании Story явно указывается одно из этих действий.
  • Business rule-based breakdown - “on the website we accept the use of VISA and Mastercard only” - т.е. breakdown команда сделает по этим бизнес-ограничителям
  • User or platform-based breakdown - “должно работать на PC, laptop, tablets” - т.е. breakdown команда сделает по этим платформ-based ограничителям
  • Acceptance test breakdown - используется в Acceptance Test-Driven Development (ATDD). Тесты пишутся до стори, стори строится чтоб пройти тесты
  • MoSCoW analysis - prioritization scheme for selecting features and functionality. MoSCoW is the acronym for Must have, Should have, Could have, and Would like to have.

Q

Validate and Control scope

A

Validate Scope

См. схему

  • PREDICTIVE: с клиентом подтверждаем interim deliverables (но до этого - через Control Quality проходим). На выходе - accepted deliverables, либо CR.
  • Agile - в конце каждой итерации (включая Product Release)

Control Scope - контроллируем work performance data against Scope Baseline
