Pre-delivery tests No Title Contents

Introduction

This document assumes that there are three distinct phases in the lifecycle of any software in use at ING:

• Development
• Transfer
• Maintenance

The development phase will normally include the following phases of the ESA software life cycle (see ESA Software Engineering Standards):

• Definition and agreement of the user requirements.
• Definition of the software requirements.
• Definition of the architectural design.
• Definition of the detailed design.
• Production: including coding, unit testing, integration testing and system testing.

The ESA transfer phase will normally include

• The pre-delivery testing of the software system prior to shipping to ING.
• The transfer of the developed software system to ING.

The ESA operations and maintenance phase will normally include:

• The formal acceptance of the delivered software system at ING.
• The operation of the software system at ING.
• The fixing of faults found during operational use.
• The enhancement of the software system.

It is the delivery phase and the formal acceptance of software systems delivered to ING that this document addresses in detail.

The objectives for ING staff during the delivery phase are to ensure that the product is usable, with reference to the user requirements for the project, by ensuring that the software has the required funtionality and is in working order; and to ensure that the maintenance phase is likely be cost-effective. It is not possible to ensure that the maintenance phase will be cost-effective a priori, but it is possible to ensure that the design and implementation of the software are of a standard which is considered maintainable and to ensure that the software system is adequately documented.

This approach to the delivery of new software systems to ING and their acceptance applies equally to internal and external development programmes. To ensure a degree of impartiality in the case of internal development programmes, staff other than those responsible for the development of the software products will be allocated the task of acceptance testing.
