Requirement administration

Many experiences from the increasingly complex aerospace system development have already been applied in a series of different industry sectors and product developments.

In a system development process, many companies confronted with a globalized competition focus on requirement management at first, since with regard to the development of innovative and complex products, they have to face an increasing number of requirements to their system. In addition, a cost-efficient and quick implementation of the ideal customer solution is required. On these terms, only tool-supported requirement management allows the optimum fulfillment of the product requirements.


In the meantime, IBM Rational DOORS® is used by many companies where it is integrated into system development processes with regard to the definition of requirements and their management. Optimally adjusted requirement management can influence many factors, such as product functionality, product development, product safety, production and quality of a product.

When you introduce IBM Rational DOORS® into your company, you should try from the very beginning to uniformly use the tool in order to ensure a closed and clear retraceability of requirements beyond organisation limits.

More often, IBM Rational DOORS® is integrated into an existing system development environment in order to reduce technical and financial risks and to increase the quality by connecting requirements in a structurized manner. Reality shows that this is a very difficult process within a company which can result in increased cost and time efforts in the beginning. But only the structurized filing and connection of requirements on the long run allows a consistent and retraceable product development. Finally, shorter implementation cycles and cost savings become clear for example by reusing product requirements with regard to the development of newly derived product variations.

Solution IBM Rational DOORS®

According to its manufacturer, IBM Rational DOORS® is the market leader in the field of requirement management in companies. In many industrial sectors such as aerospace, automotive, telecommunication which develop complex systems and have to manage many product requirements, IBM Rational DOORS® has been successfully used since many years.

Features of IBM Rational DOORS®:

  • Object-oriented capturing with attributes of requirements, with the possibility to clearly identify all object and/or contents.
  • Definition of individual data views with filters
  • Retraceability - linking of objects with the data base and to the outside
  • Independent user and user group management with LDAP authentification
  • Option to controll the access right for data
  • Configuration management with baselining
  • Change tracking and management
  • Construction of a transparent information model in a data base
  • Especially adjustable to own needs
  • Easy and adjustable operation, e.g. user guiding via Forms possible
  • Stable server/client data base system ensuring a high degree of availability
  • Wide distribution in industry


ADS provide pre-built modular solutions for IBM Rational DOORS® (even in connection with third-party products) which can be quickly adjusted to your special purpose of use.
ADS also offer support for

  • data exchange and synchronization with IBM Rational DOORS® data bases and other tools
  • Generation of documents in Word or PDF
  • Import of documents e.g. from Word, Excel, Quicksilver, Framemaker formats
  • Verification management in product validation and verification
  • Generation of traceability matrices
  • Generation of requirement lists through several documents
  • Variation management of requirements and documents
  • Change management of requirements with baseline concepts
  • Concept for user rights and access
  • Version hub of an existing IBM Rational DOORS® system during project operation

How to proceed

When introducing IBM Rational DOORS®, many marginal conditions have to be taken into consideration. The aim should always be the failure-free integration of the tool into the system development process, if possible. Thanks to our many years of experience and existing concepts and solutions, ADS is able to quickly implement IBM Rational DOORS® without disturbing the running development process. A possible approach could be, for example:

  1. Definition of requirements for the new requirement management tool
  2. Analysis of the tool environment and the existing requirement management
  3. Generation of an appropriate information model which matches the system development process
  4. Generation of a rollout concept including the required and adjusted modules for fulfilling tool requirements
  5. Generation of user guidelines and training of users to increase product acceptance

Usually, the optimization of an existing IBM Rational DOORS® system has different targets. Often, they refer to improvements of process developments or for example a version hub, in order to be able to use the latest options of IBM Rational DOORS®. The following is a possible approach:

  1. Requirement definition to optimize the system
  2. Analysis of the tool environment and existing change management
  3. Adjustment of existing DXL scripts or processes and/or new development of DXL scripts



You can reach your objectives in the field of system development more quickly and lastingly by using a structurized requirement management with IBM Rational DOORS®. Use your knowledge with regard to IBM Rational DOORS® and optimize your processes in the field of system development by using a requirement management that is especially adapted to your needs.
