Lifecycle Objectives
 Analyze business needs and document
requirements (Audience & Objectives)
 Develop Vision & Business Case
 Identify supporting portal features
 Design prototype
Evaluation Criteria
 Stakeholder concurrence on scope
definition and cost/schedule estimates
 Agreement that the right set of
requirements have been captured and
that there is a shared understanding of
these requirements.
 Agreement that the cost/schedule
estimates, priorities, risks, and
development process are appropriate.
 All risks have been identified and a
mitigation strategy exists for each.
Key Artifacts
 Vision: document the prioritized system
requirements, key features & main
constraints.
 Risk List: Initial project risks identified.
 Software Development Plan: Initial
phases, their duration and objectives
identified. Resource and cost estimation.
 Product Acceptance Plan: Reviewed and
baselined; refined in subsequent phases
as more requirements discovered.
 Software Requirement Specs: functional
& non-functional requirements.
Use-Case Model: important actors and
use cases identified and flows of
events/pages outlined for only the most
critical use cases.
 Prototype: One or more proof of concept
prototypes to support the vision & to
address very specific risks.

system
• List of portals and portlets
• Navigation flow for entry,
start/end of business transactions
and exit
• Usability design

 Develop Business Case
– Identify business drivers
– Identify technical drivers
– Cost of ownership and ROI
assessment for Portal
– Benefits assessment for
deploying a Portal
– Risks assessment
– Identification of initial audience
for the portal
– Identification of initial content
and services for the portal

11Nov 12, 2008
 Design Prototype
– List of key pages, or portals
and portlets, that the users
will visit.
– The layout of the pages and
the navigation options.
– A list of include files for
reusability of JSP code.
– The sample Portal
application that will be used
as a template, otherwise
start a new.
– Collection of images,
navigation bars, logos if
available; creative design
brief.

III.3.4. Inception – Sample Artifacts
 Could start with UI prototypes
 Could start with a domain model:
– Depending on the nature and size of the
application being built: if the application does not
have a UI, then having UI prototypes obviously
makes no sense.
– Depends on priority: Customer may place more
emphasis on domain models.
– Stakeholder recognition: discover domain objects
better and easier when working with users on UI
prototypes.

13Nov 12, 2008
III.3.4.1. Inception – Sample Artifacts
Domain Model
 A domain model helps to define major
business concepts (entities) and the
relationships among them

14Nov 12, 2008
UI Prototype & Storyboards
 UI Prototypes and Storyboards are initial screen
mockups to get a feel for how the customer visualizes
the application
 A storyboard (also known as UI Flow Diagram) shows
the flow of the screens

 A high-level architecture diagram can help with
discussions about security, scalability, transaction
management, exception handling, and other important
application-wide issues.

 Complete system design
 Create a base configuration
 Setup change/configuration management
Milestone Evaluation Criteria
 System vision, requirements and architecture are
stable
 Prototypes have demonstrated that major risks
have been addressed
 The iteration plan for construction phase are of
sufficient detail to allow work to proceed and are
supported by credible estimates
 Stakeholder concurrence that current vision can
be met if current plan is executed as per current
architecture
Key Artifacts

prototypes to explore critical functionality and
architecturally significant scenarios

likely to be architectural in nature primarily relating
to the handling of non-functional requirements

technical architecture including network, hardware,
software, security design
 Design Model: Defined and baselined. Includes
use-case realizations for architecturally significant
scenarios. Object/component model and integration

model elements (entities, relationships, tables)
defined and reviewed
 Software Development Plan: Updated and
expanded to cover the Construction and Transition
phases
 Use-Case Model: Approximately 85% complete. All
actors and use cases identified and their
descriptions captured

units, e.g. promotional
campaign, webflow
modification, etc

between Portal and all
external systems

41Nov 12, 2008
• Deploy in a Test Environment
– Install Weblogic Portal on a test
server
– Set up RDBMS and
load/migrate data
– Copy domain and server config
files from source control system
– Copy and deploy the enterprise
application from source control
system into test environment
– Use EBCC to synchronize data
from source control system to
test environment

• Conduct System and Integration
Testing
– Execute all system and
integration test plans
– Implement “continuous”
testing during development
• JUnit scripts for unit testing
• Execute all scripts every day,
even multiple times if
possible
– Each iterative release is unit,
system and integration tested
– Automate system and
integration testing if possible
• LoadRunner, JTest, etc
– Validate against user
acceptance criteria and other
system specifications

- Over-modeling an EJB
 A lot of content but the model is just verbose.
 If entire design document filled with this level of "fluff"
 quickly getting bored and dismissing the design document as "useless."
 Model the important parts of the system, not the trivia.

45Nov 12, 2008
- modeling an EJB
 Removes the fluff and focuses more on the important content.
 Use Stereotypes to model orthogonal information:
– Provide some hints to your architects and designers about what kind of
information should be included with each stereotype
– Introduce some modeling standards to your organization.

Deployment Model (1)
 Modeling the obvious: "App-Inf," "webapp," and "meta-inf"
directories add no value to the diagram.
 ONLY models the "definition" of the module

52Nov 12, 2008
 A deployment model needs to show the "definition" and the "context.“
 Good models answer some questions and raise others:
– SCM need to configure a JMS queue and a JDBC driver in the environment.
– Besides, critical information on the JMS queue and JDBC driver are also included.
 UML-Diagram Tip: every diagram should have a specific purpose.
