ALM
Application Lifecycle Management (ALM) is a continuous process of managing the entire
application lifecycle.
ALM is based on the complete traceability between business processes, functional and
technical requirements, technical components, testing and related data sets that allow us
to assess further the impact of changes.
ALM is an industrial response to the desire to reduce costs and time by ensuring the
coherence of all stakeholders activities in the software production chain.
ALM is a response to the technological and geographical complexity associated with
cultural differences of resources and stakeholders involved into the realization of
applications.

Business Process and Requirement
A Business Process is a sequence of activities with the object to produce a final result which
is definite, specific, concrete, measurable, implemented by an organized group of resources
(people, material resources, information, etc…).
A Requirement corresponds to the common structured language, that allows us to
express the need or expectation, formulated by a client or a user, and which should be
understood by all project stakeholders.
Reminder ISO 9000 definitions
- Process : A set of interacting activities that transform inputs into outputs elements.
- Requirement : need or expectation expressed, usually implied or imposed.

Modeling business is an activity that exists throughout the life cycle of an application. It is necessary to
ensure traceability of business processes with requirements, testing and technical components derived
from them, in order to take optimal account changes and impacts.

Benefits 3 :A double level of quality (Verification and Validation)
Verification, is to verify that the product :
 Works as expected.
 Meet the functional and technical specification.
 Fits correctly in the information system
 Integrate IT Production
System Test
Goal : Check the operation of the product and its interfaces between applications
Validation, is to validate that the product :
 Meet User Needs
 Meet the functional requirements
 Fits correctly in the business process
Acceptance Test
Goal : Validate good functioning of the product with business process
The consideration of business processes and requirements defining the system can
associate their tests improving the quality of the delivered system

Capitalize on Business Process
- Modify only process the tool representing
the repository profession.
- Expand the use cases to validate the
activities of business processes.
Structuring and typing of Requirements
- Structuring the repository requirements by
type.
- Structure the reference tests identical to
that of the requirements.
- Adopt adequate nomenclature.
Manage Configuration
- Place under the validated configuration requirements from
business processes.
- Extract Baseline at each major milestone of the project (or on
request)
Manage change requests
- Manage change requests priority by
analyzing the impact on business processes.
Manage traceability
- Ensure traceability between requirements
and exhaustively Requirements and Test

CONCLUSION
• With this presentation, we hope to have shared with you the steps and benefits
associated with the implementation of requirements management by taking into
account the business need in an ALM approach.
• Although the appearance setting up a requirements engineering process may
seem complex and lengthy, the return on investment has proven even that it
offers the ability to integrate a lot of changes.
• The intense rhythm of product deliveries corresponds to the current rhythm of
our customers’ needs and makes us acquire methods and tools enabling the
implementation of best practices.
• Finally, being itself based on a requirements development, linking the project
stakeholders from the beginning, it remains fully compliant with the AGILE
methods.
