15 Syste Engineeringm Software Engineering System software is a collection of programs written to service other programs It is characterized by heavy interaction with comput er hardware; heavy usage by multiple users; concur rent operation that requires scheduling, resource sh aring, and sophisticated process management; com plex data structures; and multiple external interface s Ex. Compilers, operating system, drivers etc. 16

Application Software Engineering Application software consists of standalone progra ms that solve a specific business need Application software is used to control the business function in real-time. 17 Engine Engineeringe Engineeringring /Scie Engineeringntific soft ware Engineering Characterized by "number crunching" algorithms Applications range from astronomy to volcano logy, from aut

omotive stress analysis to space shuttle orbital dynamics, an d from molecular biology to automated manufacturing Ex. Computer Aided Design (CAD), system stimulation etc. 18 Embe Engineeringdde Engineeringd Software Engineering It resides in read-only memory and is used to contr ol products and systems Embedded software can perform limited and esote ric functions Ex. Elevator, Air Conditioner, keypad control for a m icrowave oven

19 Product Line Engineering Software Engineering Designed to provide a specific capability for use by many different customers, product line software ca n focus on a limited and esoteric marketplace Ex. Word processing, spreadsheet, CG, multimedia, etc. 20 We Engineeringb Applications

Web apps can be little more than a set of linked hyp ertext files It evolving into sophisticated computing environme nts that not only provide standalone features, func tions but also integrated with corporate database a nd business applications 21 Artificial Inte Engineeringllige Engineeringnce Engineering Software Engineering AI software makes use of non-numerical algorithms to solve complex problems that are not amenable t o computation or straightforward analysis

Ex. Robotics, expert system, game playing, etc. 22 Je Engineeringnis Software Engineering (Lise Engineeringnsi) Open Source Software Proprietary Software Linux, OpenOffice, GIMP MS Windows, MS Office 2013, Adobe Photoshop

4. Hiburan dan Permainan: Dengan menyajikan aplikasi interaktif hiburan yang semakin dekat dengan kenyataan 26 Hardware Engineering vs. Introduction Software Engineering Hardware Manufactured Wear out Built using components Relatively simple Visible Defect

Software Developed/Engineered Deteriorate Custom built Complex Invisible Defect 27 Manufacturing vs. Introduction De Engineeringve Engineeringlop me Engineeringnt Once a hardware product has been manufactured, i

t is difficult or impossible to modify In contrast, software products are routinely modified an d upgraded. In hardware, hiring more people allows you to acco mplish more work, but the same does not necessarily hold true in software engineering Unlike hardware, software costs are concentrated i n design rather than production 28

Failure Engineering Curve Engineering for Hardware Engineering 29 Failure Engineering Curve Engineering for Software Engineering When a hardware component wears out, it is replaced by a spare part There are no software spare parts. Every software failure indicates an error in design or in the process through which design was translated into machi ne executable code Therefore, software maintenance involves considerably more complexity 30

Compone Engineeringnt Base Engineeringd vs. Introduction Custom Built Hardware products typically employ many standard ized design components Most software continues to be custom built The software industry does seem to be moving (slo wly) toward component-based construction 31 Visibility of Product

Produk software tidak terlihat dengan kasat mata, t ermasuk bila ada cacat (defect) dari produk Produk hardware terlihat dengan kasat mata, terma suk bila ada cacat (defect) dari produk 32 Warranty Lawsuits Mortenson vs. Timeberline Software (TS) (1993) Mortenson menggunakan software yang diproduksi TS untuk me mbuka tender pembangunan rumah sakit Software memiliki bug sehingga memenangkan perusahaan yang mengajukan proposal paling mahal (kerugian 2 miliar USD)

TS tahu tentang bug itu, tapi tidak mengirimkan update ke Morte nson Pengadilan di Amerika Serikat memenangkan perusahaan TS Uniform Computer Information Transaction Act (UCIT A) allows software manufacturers to: disclaim all liability for defects prevent the transfer of software from person to person 33 Disclaime Engineeringr of Warrantie Engineerings DISCLAIMER OF WARRANTIES.

What is Software Engineering Engine Engineeringe Engineeringri ng? Software engineering is NOT (just) programming But, of course, to be a good software engineer, one should be good at programming Software engineering is the study and application of engine ering to the design, development, testing, and maintenance of software systems Software engineering deal with issues such as: How can we develop a software in shortest time, lowest cost and with highest quality? How can we test a software in shortest time, lowest cost and with

highest quality? When we have a large team of programmers, how can we assign t he best people to development and testing tasks? How can we ensure we have inquired the software requirements f rom the client in the most efficient and effective way? 42 Software Engineering Engine Engineeringe Engineeringring Proble Engineering m Building software will always be hard. There is inherently no silver bullet (Brooks, 1987)

1. Introduction3 Software Engineering Myths 48 Software Engineering Myths Definition: Beliefs about software and the process used to build it. Myths have number of attributes that have made them insidious (i.e. dangerous). Misleading Attitudes - caused serious problem for managers a nd technical people Software Myths:

Management myths: Managers in most disciplines, are often u nder pressure to maintain budgets, keep schedules on time, an d improve quality Customer Myths: Customer may be a person from inside or ou tside the company that has requested software under contract Practitioner's myths 49 Manage Engineeringme Engineeringnt Myths Myth1: We already have a book that's full of standards and proc edures for building software, won't that provide my peo ple with everything they need to know?

Reality: Are software practitioners aware of existence standards? Does it reflect modern software engineering practice? Is it complete? Is it streamlined to improve time to deliv ery while still maintaining a focus on quality? 50 Manage Engineeringme Engineeringnt Myths Myth2: If we get behind schedule, we can add more programmers and catch up

Reality: Software development is not a mechanistic process like manufacturin g. Adding people to a late software project makes it later (Brook, 1975) People can be added but only in a planned and well-coordinated man ner Myth3: If I decide to outsource the software project to a third party, I can jus t relax and let that firm build it Reality: If an organization does not understand how to manage and control s

oftware projects internally, it will invariably struggle when it outsourc e software projects 51 Custome Engineeringr Myths Myth1: A general statement of objectives is sufficient to begin writing programs we can fill in the details later Reality: A poor up-front definition is the major cause of failed software efforts. A formal and detailed description of the information domain, function, beh avior, performance, interfaces, design constraints, and validation criteria i

s essential. These characteristics can be determined only after thorough communication between customer and developer. Myth2: Project requirements continually change, but change can be easily accom modated because software is flexible Reality: Customer can review requirements and recommend modifications with r elatively little impact on cost. When changes are requested during softwa re design, the cost impact grows rapidly. Below mentioned figure for refe 52 rence.

Practitione Engineeringr's myths Myth1: Once we write the program and get it to work, our job is done Reality: Someone once said that "the sooner you begin 'writing code', t he longer it'll take you to get done." Industry data indicate that between 60 and 80 percent of all effort expended on software will be expended after it is delivered to the customer for the fir st time Myth2:

Until I get the program "running" I have no way of assessing its quality Reality: One of the most effective software quality assurance mechanis ms can be applied from the inception of a projectthe formal t echnical review 54 Practitione Engineeringr's myths Myth3: The only deliverable work product for a successful project is the workin g program

Reality: A working program is only one part of a software configuration that incl udes many elements. Documentation provides a foundation for success ful engineering and, more important, guidance for software support Myth4: Software engineering will make us create voluminous and unnecessary documentation and will invariably slow us down Reality: Software engineering is not about creating documents. It is about crea ting quality. Better quality leads to reduced rework. And reduced rewor

k results in faster delivery times 55 Latihan Kognitif Jelaskan dengan bahasa sendiri apa yang dim aksud dengan software! Jelaskan jenis-jenis software! Jelaskan karakteristik dari software yang me mbuat berbeda dengan produk hardware! 56 Latihan Analisis Kasus
