The Software Quality Challenge

Chapter 1

Keunikan dari SQA

• Kompleksitas Produk (product complexity)

• Product complexity can be measured by the number of operational modes the product permits.

• Perwujudan Produk (product visibility)

• Software product are invisible. Defects in software products (whether stored on diskettes or CDs) are invisible, as is the fact that parts of a software package may be absent from the beginning.

• Pengembangan produk dan proses produksi (product development and production process)

• The phases at which the possibility of detecting defects in an industrial prod- uct may arise : Product Development, Product Production Planning, Manufacturing.

What Is Software Quality

Chapter 2

Definisi Software

• Komponen software terdiri dari :• Program Komputer (code)• Prosedur• Dokumentasi• Data

Definisi Error

• Software Error• eror yang terjadi pada baris kode

pemrograman

• Software Fault• kumpulan ‘software error’ yang

menyebabkan terjadinya ‘software fault’

• Software Failure• ketika telah terjadi ‘software fault’

yang tidak teratasi

Ilustrasi Terjadinya Error

Penyebab terjadinya eror

• Kesalahan pendefinisian saat fase requirements

• Terjadinya miss-komunikasi antara pihak klien dengan developer

• Adanya penyimpangan dari requirement awal

• Kesalahan pada desain algoritma

• Kesalahan pada coding yang dibuat

• Ketidakcocokan antara coding dengan dokumentasi yang diberikan

• Kesalahan pada saat pengujian software

• Kesalahan pada prosedur

• Kesalahan pada dokumentasi

SQA Definition (cont’d)

Tujuan dari SQA

Definisi QC, QA, SE

• Quality Control• “A set of activities designed to evaluate the quality of a developed or manufactured

product” (IEEE, 1991)

• Quality Assurance• Quality assurance activities substantially reduce the rate of products that do not qualify for

shipment and, at the same time, reduce the costs of guaranteeing quality in most cases.

• Software Engineering• The application of a systematic, disciplined, quantifiable approach to the development,

operation and maintenance of software; that is, the application of engineering to software.

Software Quality Factors

Mc Call’s Factor Model

Product operation factors:

■Correctness, Reliability, Efficiency, Integrity, Usability. ■Product revision factors:

■Maintainability, Flexibility, Testability. ■Product transition factors:

■Portability, Reusability, Interoperability.
