What is Software Prototyping?

The Software Prototyping refers to building software application prototypes which display the functionality of the product under development but may not actually hold the exact logic of the original software.

Software prototyping is becoming very popular as a software development model, as it enables to understand customer requirements at an early stage of development. It helps get valuable feedback from the customer and helps software designers and developers understand about what exactly is expected from the product under development.

What is Software Prototyping?

• Prototype is a working model of software with some limited functionality.
• The prototype does not always hold the exact logic used in the actual software application and is an extra effort to be considered under effort estimation.
• Prototyping is used to allow the users evaluate developer proposals and try them out before implementation.
• It also helps understand the requirements which are user specific and may not have been considered by the developer during product design.

Following is the stepwise approach to design a software prototype:

• Basic Requirement Identification: This step involves understanding the very basics product requirements especially in terms of user interface. The more intricate details of the internal design and external aspects like performance and security can be ignored at this stage.
• Developing the initial Prototype: The initial Prototype is developed in this stage, where the very basic requirements are showcased and user interfaces are provided. These features may not exactly work in the same manner internally in the actual software developed and the workarounds are used to give the same look and feel to the customer in the prototype developed.
• Review of the Prototype:The prototype developed is then presented to the customer and the other important stakeholders in the project. The feedback is collected in an organized manner and used for further enhancements in the product under development.
• Revise and enhance the Prototype: The feedback and the review comments are discussed during this stage and some negotiations happen with the customer based on factors like , time and budget constraints and technical feasibility of actual implementation. The changes accepted are again incorporated in the new Prototype developed and the cycle repeats until customer expectations are met.

Prototypes can have horizontal or vertical dimensions. Horizontal prototype displays the user interface for the product and gives a broader view of the entire system, without concentrating on internal functions. A vertical prototype on the other side is a detailed elaboration of a specific function or a sub system in the product.

The purpose of both horizontal and vertical prototype is different. Horizontal prototypes are used to get more information on the user interface level and the business requirements. It can even be presented in the sales demos to get business in the market. Vertical prototypes are technical in nature and are used to get details of the exact functioning of the sub systems. For example, database requirements, interaction and data processing loads in a given sub system.

Software Prototyping Types

There are different types of software prototypes used in the industry. Following are the major software prototyping types used widely:

• Throwaway/Rapid Prototyping: Throwaway prototyping is also called as rapid or close ended prototyping. This type of prototyping uses very little efforts with minimum requirement analysis to build a prototype. Once the actual requirements are understood, the prototype is discarded and the actual system is developed with a much clear understanding of user requirements.
• Evolutionary Prototyping: Evolutionary prototyping also called as breadboard prototyping is based on building actual functional prototypes with minimal functionality in the beginning. The prototype developed forms the heart of the future prototypes on top of which the entire system is built. Using evolutionary prototyping only well understood requirements are included in the prototype and the requirements are added as and when they are understood.
• Incremental Prototyping: Incremental prototyping refers to building multiple functional prototypes of the various sub systems and then integrating all the available prototypes to form a complete system.
• Extreme Prototyping : Extreme prototyping is used in the web development domain. It consists of three sequential phases. First, a basic prototype with all the existing pages is presented in the html format. Then the data processing is simulated using a prototype services layer. Finally the services are implemented and integrated to the final prototype. This process is called Extreme Prototyping used to draw attention to the second phase of the process, where a fully functional UI is developed with very little regard to the actual services.

Software Prototyping Application

Software Prototyping is most useful in development of systems having high level of user interactions such as online systems. Systems which need users to fill out forms or go through various screens before data is processed can use prototyping very effectively to give the exact look and feel even before the actual software is developed.

Software that involves too much of data processing and most of the functionality is internal with very little user interface does not usually benefit from prototyping. Prototype development could be an extra overhead in such projects and may need lot of extra efforts.

Software Prototyping Pros and Cons

Software prototyping is used in typical cases and the decision should be taken very carefully so that the efforts spent in building the prototype add considerable value to the final software developed. The model has its own pros and cons discussed as below.

Following table lists out the pros and cons of Big Bang Model:

Pros

Cons

Increased user involvement in the product even before implementation Since a working model of the system is displayed, the users get a better understanding of the system being developed. Reduces time and cost as the defects can be detected much earlier. Quicker user feedback is available leading to better solutions. Missing functionality can be identified easily Confusing or difficult functions can be identified

Risk of insufficient requirement analysis owing to too much dependency on prototype Users may get confused in the prototypes and actual systems. Practically, this methodology may increase the complexity of the system as scope of the system may expand beyond original plans. Developers may try to reuse the existing prototypes to build the actual system, even when its not technically feasible The effort invested in building prototypes may be too much if not monitored properly

The Samsung Galaxy S6 is the most popular-about phone at Mobile World conference this year.

The Samsung Galaxy S6 is the most popular-about phone at Mobile World conference this year, and it’s censorious that Samsung gets this right.  Luckily for Samsung, it looks like it has: the S6 is chock-full of advance, most essentially an all-new design that looks like it came from a totally another different company.

Until last year, Android—and particularly Samsung—has owned the super-sized phone space that was bizarrely retired by Apple. The Galaxy can no longer depend on being the best plus-sized phone; it has to be the very excellent phone all throughout to keep its advocate from jumping ship to iOS-ville.

And there's a very powerful disputation to be made that they've done it: Here are the some features

1. Smart Manager

View and arrange your battery life, your storage, and your security. Delete unnecessary files, or shut down apps; everything you required to limit performance all on one screen.

2. Leading the Charge

Even with Smart Manager to assist you pull your operation, you'll require to charge sometime. With the Galaxy S6 and Galaxy S6 edge, you can select quickly charging to four hours of battery life in just 10 in minutes.

3. Better Storage

The Galaxy S6 and Galaxy S6 edge are obtainable with up to 128GB of built-in storage, using the high-speed UFS 2.0 spec so conserving and loading files won't slow you down anymore.

4. Verdict

The Samsung Galaxy S6 Edge Plus is an undeniably stunning phone. It's got some of the best-performing hardware on the market, a great camera, and it's lovely to look at. The  matter is, all that lovely will cost you the  good part of £1,000 - a high premium for a device that's essentially identical to one launched earlier in the year. 

5. Specs and hardware

As you might expect from the follow-up to one of the year’s best-spaced devices, the S6 Edge plus is very, very nippy. Although it’s the same CPU as seen in the basic Edge, the Edge Plus’ octocore Exynos 7420 processor pair with an upgraded 4GB of RAM is an absolute beast, and happily handled anything we cared to theme it to. We’re not shocked, considering it’s got roughly the same amount of memory as a budget laptop. 

6. Serious Multitasking

Technically, you can multitask with any phone, but switching between apps is a discomfort in the ram. The Galaxy S6 and Galaxy S6 edge use Samsung's Multi Window™ technology to put dual apps on-screen at once, like your computer.

Review

The Good: The upscale Samsung Galaxy S6's smooth glass-and-matte-metal body, advance fingerprint reader, and suitable new camera shortcut key make the phone a stunner.

The Bad: Longtime fans will bristle at the Galaxy S6's have a permanent battery and truant dispensable storage. The phone has a suddenly reflective backing and looks embarrassingly like the iPhone 6. Battery life, while good, falls short of last year's Galaxy.

The Bottom Line: smart looks and top-notch specs make the magnificent, metal Samsung Galaxy S6 the Android phone to beat for 2015.

 Design

I've already expressed my love for the Samsung Galaxy S6 Edge's design, but in truth this is a Jekyll and Hyde device.

Place the S6 Edge face up on a desk and you can't help but be stunning with the extensive sides, rounded metal frame and inclusive premium appeal of the handset.

These are compliments usually reserved for the iPhone range and HTC's one series, but Samsung has managed to haul its design department into the 21st century  deport plastic to the lesser mobiles in its company.

There's no question there are some similarities to Apple's design here. The placement of the headphone jack, microUSB port and machine drilled speaker holes on the base mimic the iPhone 6, while the change from a volume rocker to separate metal keys on the left also suggests a Cupertino influence.

With the edges of the handset tapering to a very limited profile thanks to those dual curved displays there's no space for a SIM tray - plus that glass back isn't coming off.

Twitter finally bans Milo Yiannopoulos, one of its most notorious trolls.

Twitter has permanently suspended Milo Yiannopoulos, an editor at the conservative news outlet Breitbart and one of its most notorious trolls.

The expulsion of Yiannopoulos, who counted more than 300,000 followers on the service, comes just one day after he urged on a hateful mob that harassed ‘Ghostbusters’ actress Leslie Jones to the point that she quit Twitter.

Jones received a barrage sexist and racist messages from users, including fake messages made to look like they came from her account. With little way to fight back, she decided to quit the service on Monday “with tears and a very sad heart.”

This is far from the first time that Yiannopoulos has courted controversy on Twitter. He became a driving force in GamerGate, which vaulted him to cult future status on certain parts of the internet. He then lost his verification badge, which Twitter typically gives to members of the media and celebrities, in January, which only seemed to amp up his interest in offending Twitter’s management and many who use the service.
TechCrunch reached out to Yiannopoulous and will update if we hear back.
In a statement to TechCrunch, Twitter said:

People should be able to express diverse opinions and beliefs on Twitter. But no one deserves to be subjected to targeted abuse online, and our rules prohibit inciting or engaging in the targeted abuse or harassment of others. Over the past 48 hours in particular, we’ve seen an uptick in the number of accounts violating these policies and have taken enforcement actions against these accounts, ranging from warnings that also require the deletion of Tweets violating our policies to permanent suspension.
