It is necessary to note that various models have effective results in different applications. However, the most important factor that influences the project outcome is the planning and implementation process (Blanchard and Fabrycky 31). With its customizable spreadsheet interface and powerful collaboration features, Smartsheet allows for streamlined project and process management. Use Smartsheet’s SDLC with Gantt template to get started quickly, and help manage the planning, development, testing, and deployment stages of system development. Create a timeline with milestones and dependencies to track progress, and set up automated alerts to notify you as anything changes.

Agile Development means constant evaluation by both developers and customers (notice the term “Collaboration”) of each day’s work. The fifth step of the IS SDLC is to maintain the system that you have implemented. This involves monitoring, evaluating, and improving your system, using the feedback and performance data as a source. You should also document and communicate the changes and updates of your system.

There are other, fundamental reasons why low-cost, high-quality projects done quickly are so difficult to achieve. Which of these implementation methodologies to use depends on the complexity and importance of the old and new systems. Even if an organization determines to buy software, it still makes sense to go through many of the same analyses that they would do if they were going to build it themselves. This is an important decision that could have a long-term strategic impact on the organization. Various definitions of the SDLC methodology exist, but most contain the following phases. By making access to scientific knowledge simple and affordable, self-development becomes attainable for everyone, including you!

This generic SDLC model, designed by the National Computing Center of the United Kingdom in the late 1960s, was described in 1971 by A. Ensure the consistency between our system requirements and system elements. [Outcome 2] System requirements are allocated to all the elements of the system.


Furthermore, developers will often create a software requirement specification or SRS document. The analysis stage includes gathering all the specific details required for a new system as well as determining the first ideas for prototypes. All changes to a system must be formally controlled via the Forensic Laboratory change control process, as defined in Chapter 7, Section 7.4.3.

Besides classifying a program language based on its generation, it can also be classified by whether it is compiled or interpreted. As we have learned, a computer language is written in a human-readable form. In a compiled language, the program code is translated into a machine-readable form called an executable that can be run on the hardware.

Integrated Development Environment

The most common data model used is the entity relationship diagram. The four objects or features of Access 2010, tables, queries, forms, and reports, interact in various ways to enable users create a functional relational database. We have two categories of data flow diagrams, which are logical and physical.

The standards for HTML are set by a governing body called the World Wide Web Consortium. The current version of HTML is HTML 5, which includes new standards for video, audio, and drawing. Each type of operating system has its own JVM which must be installed, which is what allows Java programs to run on many different types of operating systems. The Lean model is also often used for software development purposes. The correct use of the System Development Life Cycle has a large number of benefits.

Programming Tools

However, to be productive, he or she must be able to check the syntax of the code, and, in some cases, compile the code. To be more efficient at programming, additional tools, such as an integrated development environment (IDE) or computer-aided software-engineering (CASE) tools, can be used. It means that you cannot complete a low-cost, high-quality project in a small amount of time. However, if you are willing or able to spend a lot of money, then a project can be completed quickly with high-quality results (through hiring more good programmers). If a project’s completion date is not a priority, then it can be completed at a lower cost with higher-quality results.

  • There are plenty of tools available, such as Adobe XD or InVision, that make this process much easier than ever before.
  • The System Development Life Cycle (SDLC) provides a well-structured framework that gives an idea, of how to build a system.
  • The developer must formulate plans for various aspects like operating systems, security features, hardware, physical development, and programming among others.
  • This type of scenario meant that there was not a true need for refined methodologies to drive the life cycle of system development.

Some companies see so much value in the model that it is used for other projects, including non-technical projects and activities. The SDLC process consists of seven phases, including planning, design, testing, and maintenance. Every phase can be supplemented by various tools to support the phase’s information systems development life cycle main goal. Besides SDLC, there is another concept that is a cornerstone for the entire lifecycle of product and system planning. Systems Analysis & Design (SAD) is a process during which specific information systems are developed that effectively support hardware, software, or people.


Sometimes a combination of higher and lower level languages is mixed together to get the best of both worlds. Early languages were specific to the type of hardware that had to be programmed. Each type of computer hardware had a different low level programming language. In those early languages very specific instructions had to be entered line by line – a tedious process. Once a new system has been introduced, it enters the maintenance phase.

System Development Life Cycle Guide

Using these two forms of feedback, the team determines whether they should continue in the same direction or rethink the core idea behind the project, change the functions, and create a new MVP. Several iterations of the MVP are developed, with new functions added each time based on the feedback, until a final product is completed. Aligning the development team and the security team is a best practice that ensures security measures are built into the various phases of the system development life cycle.
