Comparison between gb/t17544 and gb/t25000.51

1 Background 1.1 Emergence of the new national standard

over time, gb/t16260-1996 has been revised to gb/t16260.1-2006 (which includes concepts such as the use of quality). gb/t16260.1-2006 equivalent to ISO/IEC 9126-1:2001. In the new Square series standard: ISO/IEC 9126-1:2001 will be revised to ISO/IEC 25010. ISO/IEC 12,119:1994 has been revised to ISO/IEC 25,051:2006 and overcomes some of the difficulties and ambiguities in ISO/IEC 12,119:1994. GB/T25000.51 is a revised version of gb/17544-1998, equivalent to ISO/IEC 25,051:2006. One of the objectives of the revision is to harmonize with the square series of standards. This standard, released in September 2010, was formally implemented on February 1, 2011 and is used in parallel with gb/t17544 between September 2010 and February 1, 2011, and gb/t17544 is void after February 1, 2011. 1.2 software testing should be adapted to the new standard

With the new software testing GB gb/t25000.51 release and implementation, as well as the old national standard gb/t17544, the requirements for software testing experiments need to be based on the new national standard implementation of evaluation activities. Therefore, we must make a comparison to the new and old national standard to determine whether the evaluation ability of the laboratory can meet the requirements of the new national standard.

The new GB gb/t25000.51 is a revised version of the gb/t1755, retains the original national standard of software quality requirements of the characteristics, but at the same time for the new GB T1620.1 more close, so there are some changes; therefore, we need to test the laboratory for the new national standard for research, while comparing some of the old national standards of quality requirements, through the two version of the national standard for better application of the new GB gb/t25000.51 implementation of laboratory evaluation activities. 2 Preliminary comparison of the change of 2.1 GB name

Old GB: gb/t17544-1998 "Information technology software package quality requirements and testing" equivalent to the International standard iso/iec12119-1994 "Information technology software package quality requirements and testing"

New national Standard: gb/t25000.51-2006 The quality requirements and evaluation of software engineering products (SQuaRE) commercial spot (COTS) software products ' requirements and testing rules are equivalent to international standards iso/iec25051:2006 software Engineering- Quality requirements and evaluation of software products (SQuaRE)-quality requirements and testing rules for commercial off-the-shelf (COTS) software products

by the above-mentioned GB name can be seen new national standard to adapt to the requirements of the new national standards, with the new international standard changes in the national GB at the same time revised. At the same time the old national standard is the "Information Technology package" requirements, and the new national standard is the "commercial spot (COTS) software PRODUCT quality requirements." 2.2 content comparison

The following compares references from gb/t25000.51-2006 the "Preface" section:

This standard is gb/t17544-1998 "Information technology software package quality requirements and testing" revised version. The purpose of the revision is to align with the square series standards. The differences between this standard and gb/t17544-1998 are as follows:

1) gb/t17544-1998 equivalent to the use of iso/iec12119:1994, because iso/iec12119:1994 was revised to iso/iec25051:2006, so the new standard equivalent to the use of iso/iec25051:2006;

2) The structure of the new version of the standard has been adjusted and modified, gb/t17544-1998 a total of 4 chapters 3 appendices, the new version of the standard 7 Chapters 3 appendices and a reference document;

3) The content of the new standard has also been significantly modified-the scope of application of the new version of the standard has been expanded. The term part made additions and deletions, the new standard of the 4th chapter and the old version of the 3rd chapter of the standard is basically the same, but the original 3.3 of the name "program and data" to the new version of the 4.3 "Quality requirements of the software." But the new standard is more closely related to gb/t16260. The requirements for software products are basically expressed in terms of gb/t16260.1-2006. The new version of the 5th chapter of the standard of the old version of the 4th chapter, the change is larger, the new version of the standard to delete the test activity, mainly for the test document, especially the test plan, test procedures, test report of the preparation of the requirements. The new standard adds two chapters, namely the 2nd Chapter "conformity" and the 7th chapter "conformity evaluation rules". The 2nd chapter describes the conditions under which COTS software products conform to this standard. The 7th Chapter stipulates how to evaluate COTS software products and how to compile compliance evaluation reports on compliance.

4) The appendix of the new standard has also been changed, and the appendix of "Examples of product description" has been deleted from the old standard.

5) added the "Application Guide for COTS software products in high integrity Application Systems" and "How to use this standard" two appendices. 3 Details comparison 3.1 Chapter comparison

Each section of the new standard gb/t25000.51 and gb/t17544 is compared in the table below:

gb/t17544-1998	gb/t25051-2009	Compare Results
1. Scope	1. Scope	GB/T25000.51 is suitable for commercial off-the-shelf (COTS) software products; gb/t17544 applies to software packages; The new standard gives a more specific range, but limits the number of commercially available products.
No	2. Compliance	The old standard does not require, in the new standard new additions, mainly used to evaluate the software spot products for the national standard compliance requirements.
No	3. Normative reference Documents	The old standard does not require that the new standard be added to this section, highlighting the new standards for gb/t16260 compliance requirements. The new standard is closer to gb/t16260.1.
2. Definition	4. Terminology and Definitions	The new standard gives 11 terms and definitions, while the old standard has only 7 definitions, and the specific contents refer to the new and old standards respectively.
3. Quality Requirements	Requirements for 5.COTS software products	The name has changed, but this part of the new and old standards are for the SOFTWARE product quality requirements, are divided into three parts, two types of document requirements and software products themselves.
3.1 Product Description	5.1 Product Description Requirements	The new standard 10 requirements, the old standard 8 requirements; This part of the new standard adds "usability" and "User use quality" requirements, one is the new national standard for the product description requirements, one is to increase the standards of a software feature requirements.
3.2 User Documentation	5.2 User documentation requirements
