Repository could be anything


PMBOK Requirement Types Business requirements, which describe the higher-level needs of the organization

as a whole, such as the business issues or opportunities, and reasons why a project has been undertaken.

Stakeholder requirements, which describe needs of a stakeholder or stakeholder group.

Solution requirements, which describe features, functions, and characteristics of the product, service, or result that will meet the business and stakeholder requirements. Solution requirements are further grouped into functional and nonfunctional requirements:

o Functional requirements describe the behaviors of the product. Examples include processes, data, and interactions with the product.

o Nonfunctional requirements supplement functional requirements and describe the environmental conditions or qualities required for the product to be effective. Examples include: reliability, security, performance, safety, level of service, supportability, retention/purge, etc.

Transition requirements describe temporary capabilities, such as data conversion and training requirements, needed to transition from the current as-is state to the future to-be state.

Project requirements, which describe the actions, processes, or other conditions the project needs to meet.

Quality requirements, which capture any condition or criteria needed to validate the successful completion of a project deliverable or fulfillment of other project requirements.

BABOK includes Business, Stakeholder , Func7onal, Nonfunc7onal and Transi7on requirements


Repositories: Behind the Scenes What is really being asked of employees?

Tacit Knowledge (I understand something

Its in my head)

Codify (Write down, or model the knowledge)

Store (Select how

and where I put it)

Repository

Tacit Knowledge (I understand something)

Search (Find what

I need)

Utility (Understand why to use this knowledge)

De-Codify/ Interpret (Read, view,

interact)

Motivation Assumptions Have the

desire to help others

Have training & discipline

Have desire to

learn

Faster to go to the repository

than to just ask someone

Differentiating Repository Variations


Requirements Hoarding

Requirements Modelling

Factual and Contextual Knowledge with Organization and Codification

All Knowledge, No Organization Extremely High Level of Codification


Golden Rules to Consider

People are more willing to search for knowledge than share

Every repository needs subject context to get contribution

Codification is a balance: o Too little and its hoarding o Too much and its a single purpose system

Two types of integration need to occur to make repositories useful:

1. Make the repository part of the daily work environment 2. Insure the repository interacts with other information

systems within the organization


REPOSITORIES: WHAT CREATES VALUE?


Context is THE most important issue

Impact Who or What does it impact?

(Service, Persona, Process, Data, Rule)

History (Log of change,

approval and Implementation)

Work Flow (Who did the work, whats next to do, issues, defects,

resolutions)

Intent (Expected

benefits for a sponsor)

PROJECT

Requirement Attribute Requirement Feature

WORK PRODUCTS (Attachments, models, etc.)

COLLABORATIVE

(Comments, shared actions,

etc)

STATE (Draft, Approved,

etc)

VERIFICATIONS

(Conditions of value)

CONNECTED REQUIREMENTS

1) Maintain the

synchronization between PLAN and ACTION layers

2) Facilitate interaction between the Owners and Analysts

3) Make it a closed, self-updating, loop

History

Crea9ng Large Requirement Documents is an archaic prac9ce brought forward from the 70s

Requirement data is dynamic and no longer ts word processing or spreadsheet sofware

Crea9ng large paper requirements documents is slow, inecient, and costly


Conclusions about VALUE and Best Practice What is Reusable

First and foremost - the CONTEXT of the requirements is necessary: o An effective project archive is a showcase of context who, did what, why,

using which workflow (how), to what outcome. o Context is surprisingly repeatable - the same business conditions tend to

trigger a project

Repositories are the only way to synchronize architecture and IT service planning to the execution layer (project layer) of the business

Repositories allow you to change the way requirements are done o Manage data, not documents o Do requirements in layers

Finally what is likely the #1 requirements repository today?


BUILDING THE BUSINESS CASE FOR REPOSITORIES AND STANDARDIZATION


Building your business case

The 2% rule: 1.5% to 2% of requirements change per month in an implementation over 24 months: o ~40% of requirements change at least once and ~ 10% of requirements

change two or more times o Cost of defect and change management vastly outweighs the cost to create

The 2X rule: If stakeholders routinely tell the analyst they are taking 2X the time expected, OR, analysts are taking 2X the time budgeted o Its a signal of structural problems and you need the efficiency gain o The payback is in the discipline

The 3X rule: Can you use a stored asset 3 times? o The reuse of the asset vastly outweighs the effort to create and

store.

Quality, Agility, Stakeholder Satisfaction

Why do you need a repository?

MAKE THE REPOSITORY PART OF THE BUSINESS PROCESS


Large Documents or a Wall of Post-It Notes

Large Requirement Documents A Wall of Post-It Notes

Requirement data is too dynamic to use either of these methods.

How can this support changing requirements?

Can you imagine what the chief compliance ocer might say when told these are

requirements for one of our strategic systems?

Iterative and Incremental Itera0ve Incremental

When you work itera0vely you build what you can in one itera9on, then review it and improve it in next itera9on and so on un9l its nished. Requirements are built going through a con9nuous set of reviews by stakeholders and the business analyst. Business Analysts receive comments from stakeholders, make improvements to the requirements, and ask for comments

When you work incrementally you add components piece by piece un9l you are nished. Requirements are built in layers, star9ng with high level business objec9ves, decomposed into features, func9onal requirements, and various layers of detail for each requirement.
