Important examples of this includes quality assurance and documentation, software that may not work, and the user has no idea how to interact with is unsurprisingly seen as unprofessional. A mildly humorous consequence of this definition is that Sommerville indirectly states that open source software may never be professional: floss is seldom extensively documented and ALWAYS provided AS-IS, thus no QA guarantees.]]> 2022-11-06 20:39:17 UTC https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2371990231 Ludvig Nilsson https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2371999050 One way to view the distinction between is to ask whether the developer or the consumer has control over software specification. If the developer has it then it is generic software, and they have all the power, the consumer is mostly just along for the ride, if the developer wants a GUI redesign but user not then it is bad times for the user. The other case is bespoke software, and now the consumer is calling the shoots and may dictate to the developer what features shall and shall not be priorities.]]> 2022-11-06 20:53:14 UTC https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2371999050 Christofer Goulas https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2372003687 A professionally developed software system consist of several separate programs and configuration files to set up these programs.

This claim is a bit more agreeable when one considers the counterfactual: only going on gut instinct and following no particular structure at all does not seem like a recipe for success when developing, say, a missile guidance system. ]]> 2022-11-06 21:11:52 UTC https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2372010513 Christofer Goulas https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2372024485 Generic software development are made for similar companies that have similar types of business needs. Hence, software companies develops generic software on their own for groups of customers with similar requirements.
Custom software development develops products for an individual clients and that can be a  company or a group of persons.
Generic clients may need to do some changes so the software works for the companies specific needs.

It is designed and developed for the general public to use. On the other hand, customized software are developed for a specific reason on a more individualistic customer demand. In practice for users of generic products, this means that the product may not be applicable for their specific intention of use or an upgraded version of the generic product may hinder the user to use it.]]> 2022-11-07 08:37:55 UTC https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2372685802 Oscar Ågren https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2372722781 The software process comes with some benefits that in turn reduces costs in the long run.

Furthermore, professional softwares use techniques and procedures making them more reliable, cost-effective and scalable compared to computer programs built personally. Other key differentiating factors could be that professional softwares require documentation, user support manuals, user platform support and special consideration to maintenance and scalability. Moreover, programs built professionally are usually developed more quickly then computer programs that are built and delivered for non-professional use. ]]> 2022-11-07 09:24:33 UTC https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2372739665 Johan Palm https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2372765984 The software developed for a customer will most likely be used and altered by other personel. To make the transition of one developer to another, documentation about the use and design of the code becomes important. To seamlessly being able to update and change the code no matter the developer is of high value to a customer. Then it is no longer only about the program but also all the information surrounding it.]]> 2022-11-07 09:45:27 UTC https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2372765984 Johan Palm https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2372771979 Generic software development is targeted at a larger purpose while custom software is highly specific. The custom software is developed purely by the standards of the customers needs. In practice the users of generic software products might have to alter the program to fit their purpose.]]> 2022-11-07 09:49:47 UTC https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2372771979 Mohammad Sameem Ahmadzai https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2372774316 The generic- and custom softwares differ in terms of software specification, meaning who owns the specification. Generic softwares are normally developed upon market requirements and for everybody. Here the developer owns the specification of how the software might look like. Conversely, custom softwares are developed upon specific customer requests for example an ERP system for a company. It is important to note that these differences are now increasingly blurred into each other or in other words a large number of generic and custom software systems are built on top of each other. ]]> 2022-11-07 09:51:25 UTC https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2372774316 Johan Palm https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2372785171 In software the cost of constantly making new, slightly better, products is much higher compared to constantly updating your product.

This makes the devlopement and modification of softwares greatly cheaper since the program does not need to be built from the scratch. ]]> 2022-11-07 10:02:20 UTC https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2372788805 Jonas Ouadih https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2374519346 Professional software made for customers is not simply develop and deliver since there is a responsibility to document, maintain and continuous development within a dedicated team.

This is a safety-critical system and thus needs to be thoroughly analyzed and documented before the implementation begins. It could be very dangerous for the driver and the other drivers in the environment in which the system is implemented if it was implemented too early. Therefore, the waterfall model is suitable for this system.

ii) A university accounting system that replaces an existing system.

Since it already is an existing accounting system at the university, it is convenient to configure the system in place and integrate the configuration to replace the old system. There are a lot of features and functionality in the old system that most probably stay the same in the new, which make the integration and configuration model the most suitable.]]> 2022-11-10 08:03:19 UTC https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2378212553 Oscar Ågren https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2378220668 Incremental software development is designed for development where the software is not fully mapped out or can't be fully planned. By incrementally adding functionality and features, one can more effectively reverse functionalities and features that the customer sporadically decides to not be included, as well as add new which may fit the customers new ideas.

This means that each phase will go trough a  separate process, where testing phase will be very important in this type of project.

A system to control anti-lock braking is a safety-critical system where dependability is the most important factor. I suggest using the Waterfall Process when developing this system. A safety-critical system should not be subject to constant changes, because this could degrade the system structure. Instead, a safety-critical system needs to be well planned with well-specified requirements, and using the Waterfall model means approving each phase before moving on to the next making it easier to analyze and oversee project progress. 

ii) A university accounting system that replaces an existing system

For this system I suggest using a reuse-oriented proces. Because the accounting system is to replace a previous system, searching for components to use should be easy, which can help reduce cost, risk and speed-up delivery.

The embedded control system for antilock braking in vehicles must be safety critical because there are no room for errors. These system are burned in to read-only memory and therefor very expensive to change. It also require extensive verification and validation due to the extremely high costs of recalling cars because of software problems so the waterfall model should be the system to choose. 
          The waterfall model is a plan driven process where you plan, schedule and test all the process activities     before moving to the next phase and ultimately developing/completing  the end product.

    2. Accounting systems are stand alone systems produced by a companies/organisations for customers able to buy them.

The user should either specify the amount fuel such as a certain liters  or either let the system to fully tank the car (The system should know when the tank storage is full to stop flowing fuel or when the user runs out of money, or the fuel nozzel gets out of contact with the car tank to avoid flowing fuel on the ground). The amount of fuel and corresponding money should be displayed in real time by a nice interface. User authentication and enough money check should not take long time (i.e., longer than 5-10 seconds).
    When the desired amount of fuel has been delivered and the payment has been through, the user should be given confirmation by printing an encrypted receipt where bank details are hidden. ]]>     2022-11-11 20:07:54 UTC https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2380596411     Oscar Widegre https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2381492320 To produce professional software does both documentation and technics/methods to ensure the final product. The documentation ensure that support, version handling and new developers can be joined. Note, user guides is part of the documentation. The purpose of documentation is to specify the product, remembering details and aspects, not repeating mistakes and make the rolls such as developer, owner and user independent of specific persons which means that the products value increase. Technics/methods how the product will be used (use cases) and for example how security will be provided. The purpose of this technics/method is to validate the product, shrink the amount of work to develop the product and to ensure the value of the product.

A generic product is run by the developer team and the bespoke software is run by the costumer. For the suer of a generic software does it mean in particular that the user impact is very small, thus it can be hard or impossible to customize the product and or get changes at a certain time.

It is nearly impossible to ensure a software system which will provide all functionality needed and required in the futter both due to technical innovation and organization development. Thus, will it be cheaper to use technics and methods which has been validated to develop software systems to avoid costly changes/updates later. Simply, do not reinvent the wheel.

A waterfall model requires extensive planning and designing before moving on to the implementation phase.

    ii) A university accounting system that replaces an existing system may probably reuse several existing components and services. The most suitable software process model for this is the integration and configuration model, which lowers cost and development time by reusing and configuring existing components into a new usable system.]]>     2022-12-15 16:04:06 UTC https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2422033137     Christoffer Chiniquy christofferchiniquy https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2422045872 One of the many advantages of incremental software development is the ability to quickly implement new features and alter existing ones while getting rapid feedback from the customer about the features implemented. This software process model is ideal when there is no clear vision of the expected functionality of the final product. One caveat of this model however is that the system eventually degrades over time as it continuously evolves with more and more features.]]> 2022-12-15 16:14:16 UTC https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2422045872 Christoffer Chiniquy christofferchiniquy https://padlet.com/alessiobucaioni/2getv9f85ttrijxy/wish/2422058790 User requirements specify the functionality of the system from the users point of view.
