Managing Experience for Requirements Elaboration
MERE
|
|
Introduction
The MERE process participates to the improvement of Requirements Engineering. For
this, it defines a requirement elaboration procedure in which the requirements
are derived from factual experience sources. Then, it ensures the requirements
implementation in the final product of the company.
Summary Description
The MERE process is split into two parallel processes and four main steps altogether:
- Rules and Recommendations Derivation (RRD): This continuous process
mainly consists of two main steps:
- Research and analysis of significant experience facts. This step is
called Experience facts selection and memorisation process.
- Translation of the selected significant experience facts into
generalised Requirements in order that: in case of incidents: same problems do
not appear again, in case of good solutions: same good solution may be reused.
This step is called Requirements elaboration and memorisation process.
- Rules and Recommendations Application (RRA): RRA is a class of processes,
from which a single process is instantiated each time an application is started.
It mainly consists of two main steps:
- Selection of the requirements that must be applied to one given
project. Use and application of selected requirements. This step is called
Requirements application process.
- Verification that all the selected requirements have been applied.
This step is called Verification of Requirements application.
Benefits and Application Areas
The introduction of the MERE process in the activities of a company will enable a
systematic reuse of factual experience in an efficient way and so, it will enable:
- improvement of the quality and safety of products (RAMSS
performances) and improvement of the quality and safety of processes,
- improvement in the adaptation between human behaviour and machine
behaviour,
- improvement in the adaptation to the users needs.
This will lead to the reduction of the number of modifications due to
misfunctionings and to the elaboration of experience/requirements data bases
(participation to the Capitalisation of Knowledge). It will lead to the reduction
of the time spent for experience treatment thanks to the retrieval of already
solved similar problems.
The experience capitalisation and the associated requirements derived from are
part of the Corporate Memory process covering the experience on the product.
MERE process is applicable to any field of activities from small to large
companies. MERE process contributes to the quality improvement of any activity
on which it is applied and so, it can be used to obtain an approved quality
label: an ISO 9000 appproval, attribution of a higher level in SEI Capability
Maturity Model and so on.
How to Apply
The MERE process must be tailored according to the domains of activities, the
size and the points of interest of the company. A start-up and tailoring guide as
part of MERE show how to introduce and adapt MERE due to the needs of a
particular company.
RAMSS = Reliability, Availability, Maintainability, Security and Safety.
