Dynamic Object Oriented Requirements System

What is IBM DOORS?

ERM DOORS (Formerly known as ‘IBM Rational DOORS’ and current IBM name ‘Engineering Requirements Management DOORS’) is a software solution which helps to manage requirements and specifications in an easy and reliable way.

What is IBM DOORS used for?

One of the main use-cases is to ensure the alignment of order contents between suppliers and OEM’s. In contrast to the management of documents (user Requirements/Lastenheft as opposed to Specifications/Pflichtenheft), IBM DOORS makes it possible to directly relate the statements across these documents on the basis of link relationships, regardless of the composition of the documents and their chapter structure.

This is not possible with conventional tools such as MS Word or Excel and is a prerequisite for the assurance of matching content across the stakeholder documents.

How does IBM DOORS work?

The user interface of IBM DOORS is very much like a mixture of MS Word and Excel. It uses Modules which are comparable to a Word Document in which the user works with Headings and chapter structures on one side. On the other side, any paragraph has multiple columns, like Excel for attributes like priority, unique ID’s, descriptions…
Especially the unique ID’s of any requirement (artifact) is the most important difference to MS Word or Excel. Based on this automatically generated unique ID, unique link relationships can be established and managed. This is the basis for traceability analysis, e.g. impact of changes, test coverage…
Traceability analysis is known as a common prerequisite for an efficient and precise comparison of the customer’s requirements with the supplier’s specification.This is not possible with conventional tools such as MS Word or Excel and is a prerequisite for the assurance of matching content across the stakeholder documents.

How much does IBM DOORS cost?

This solely depends on the use-case. For example a very common and easy use-case is as follows: When placing an order, it is mandatory that the management of the order specification between OEM and supplier is done on the basis of DOORS. In this situation usually a single user license is sufficient and costs €5000,- which includes half a day of web based training.

More information about the various license models can be found here.

How to install IBM DOORS

IBM DOORS is a client-server application. This means that the data is located on a server and the respective clients can access it. For this purpose, IBM DOORS uses a very efficient proprietary database that scales performantly even with extremely large data volumes and distributed teams.
This is the prerequisite for IBM DOORS to be used with large globally distributed teams.
However, there is also the possibility of a quick and easy installation of server and client on the same computer for single user use.

Such an installation and a first start-up can be done within one hour (assuming professional competence and administration rights on the computer).
In case of a first installation, start-up and basic configuration we are happy to accompany our customers if they do not have any experience in using IBM DOORS yet.

IBM DOORS hardware requirements

The IBM DOORS server can run on Windows and Read Hat Linux, the DOORS client on Windows.

The basic hardware requirements are roughly as follows:

  • CPU from Dualcore / Dualthread
    (e.g. Intel Xeon 2.0 GHz – ∞ GHz)
  • RAM starting at 2GB dedicated memory
  • HDD/SSD Initial 200Mb (without data)
