RAPID ACCESS DEVELOPMENT MODEL
RAD refers to a type a software development methodology; which uses minimal planning in favor of rapid prototyping. The planning of software developed using RAD is interleaved with writing the software itself. The lack of extensive pre-planning generally allows software to be written much faster and makes it easier to change requirements.
Mnemonics do not relate to Features (only Strengths & Weakness)
Features:
{Some of the features}
- Key objective is fast development and delivery of a high-quality system at a relatively low investment cost.
- Active user involvement is imperative.
- Iteratively produces production software as opposed to a throwaway prototype.
- Produces documentation necessary to facilitate future development and maintenance.
- Key Emphasis is on fulfilling the business need while technological or engineering excellence is of lesser importance.

- TOP: TOP = दिमाग , Dimag से concentrate करते है।
- NOSE: लड़के/लड़की का nose देख के पता चल जाता है i.e Quick initial review {पहली नज़र मे देख के ही पसंद आ जाता/जाती है।}
- MOUTH: आज कल के mouth बहुत Rapid चलते है। [Rapidly change system design]
- RIBS: Ribs का Operation (version) करवाना पड़ा। [रिब्स काम नहीं कर रही थी operation करवाना पड़ा ]
- LIVER: आजकल Liver जल्दी ख़राब हो जाता है (Quickly)
- JOINTS: जिनके joints atche है उनकी speed fast होती है
- KNEE: आजकल knees के operation के लिए new features आ गए है।
- FIBULA: अगर Fibula ख़राब हो जाये तो पूरी body एक Inconsistent system बन जाती है।
- BALL: ball को Goal तक पहुंचाने के लिए Well defined interface required होते है।
- SAND: दिल्ली/मुंबई मे जमीन की ज्यादा से ज्यादा Requirement है [more requirement]
Module reference:
Strengths:
- The operational version of an application is available much earlier than with Waterfall, Incremental, or Spiral frameworks: Ribs का Operation (version) करवाना पड़ा।
- Because RAD produces systems more quickly and to a business focus, this approach tends to produce systems at lower cost: आजकल Liver जल्दी ख़राब हो जाता है (Quickly)
- Quick initial reviews are possible: लड़के/लड़की का nose देख के पता चल जाता है
- Constant integration isolates problems and encourages customer feedback.
- It holds a great level of commitment from stakeholders, both business and technical, than Waterfall, Incremental, or spiral frameworks. Users are seen as gaining more of a sense of ownership of a system, while developer are seen as gaining more satisfaction from producing successful systems quickly.
- It concentrates on essential system elements from user viewpoint: TOP = दिमाग , Dimag से concentrate करते है।
- It provides for the ability to rapidly change system design as demanded by users: आज कल के mouth बहुत Rapid चलते है।
- It leads to a tighter fit between user requirements and system specifications
Weakness:
- Fast speed and lower cost may affect adversely the system quality: जिनके joints atche है उनकी speed fast होती है।
- The project may end up with more requirements than needed (gold-plating): दिल्ली/मुंबई मे जमीन(SAND) की ज्यादा से ज्यादा Requirement है
- Potential for feature creep where more and more features are added to the system over the course of development: आजकल knees के operation के लिए new features आ गए है।
- It may lead to inconsistent designs within and across systems: अगर Fibula ख़राब हो जाये तो पूरी body एक Inconsistent system बन जाती है।
- It may call for violation of programming standards related to inconsistent naming conventions and inconsistent documentation,
- It may call for lack of attention to later system administration needs built into system
- Formal reviews and audits are more difficult to implement than for a complete system.
- Tendency for difficult problems to be pushed to the future to demonstrate early sucess to management.
- Since some modules will be completed much earlier than others, well-defined interfaces are required: ball को Goal तक पहुंचाने के लिए Well defined interface required होते है।

Hi, I would really love if could have provided the rest videos of sdlc sub parts
ReplyDeletePlease share videos on chapter 7. Much needed ..Please 🙏🙏🙏
