For software to be created, a software development process is indispensable, depending on the type and technology used , software developers will apply different processes. To learn more about the software development process and process types, let’s go to the following Tech Town article.

the software development process ?

All work in a software development project must be planned, divided into phases and arranged in a logical sequence. This order is called the software development process or software development life cycle . Each step in this process is very important and affects the whole system, so this is the most basic knowledge that software developers or business owners need to know.


The more streamlined and scientific the development process is, the more optimized the software product will be and the better it will work.

Steps of the software development process

At Tech Town, we implement a software development process in 7 steps to ensure the quality of the product created:

1. Make a plan

The first step after receiving the partner’s request, our engineering team will proceed to develop a development plan.


software development project , Tech Town always proposes at least 2-3 plans to help partners have more options and suitable solutions.

2. Requirements Analysis

Next, the programmers will go into each step, analyzing data from partners to produce the most detailed report on the software development plan . This is an important step to determine the final product quality.

3. Designing and Prototyping

After analyzing the specific requirements of the partner, the Tech Town team will design preliminary drawings as well as create a clickable prototype to shape the software and validate the requirements. In the Agile software development process (we’ll talk about it later) this step is the bridge to all later stages.

4. Start programming

Next, software developers use programming technology and appropriate programming languages to create products with high interoperability in the market and help businesses achieve project success.

5. Testing

Testing is an integral step in the software development process . In order to create a finished product, the product needs to be tested many times to ensure quality control and to correct errors early in the development process.

6. Project implementation

Once agreed on the quality and operability of the software, the developer will proceed to hand over the software to the enterprise for project implementation.

7. Maintenance

At Tech Town, we will always follow up to support and correct arising errors of the software even after handing over. With each product created, we are committed to lifetime support, warranty, product upgrade and expansion advice, helping partners and customers have the best software use experience at all times.

Software development models

Waterfall model – Waterfall model

A model of the software development process in which the development process looks like a flow, with phases being executed in strict order and without repetition or “jumping” of stages – including Includes: Requirement analysis, design, implementation, testing, launch and maintenance.

Stages of the waterfall model

  •     Requirements gathering: This is the stage of determining the functional and non-functional requirements that the software system needs. The output of this phase is the requirements specification document. This document will form the basis for the next phases to the end of the project.
  •     System Analysis: It is the stage of setting standards for the software system to meet the requirements of the customer. This phase performs analysis and design of the software system.
  •     Coding: Is the stage of product implementation based on requirements specification and module design document.
  •     Testing: Tester will receive product from programmer and perform testing for components and system testing. The final stage of testing will be Acceptance Testing, this phase also includes the participation of partners.
  •     Implementation: Deploy the system to the customer’s environment.
  •     Operations & Maintenance: This is the installation, configuration and user manual phase for partners. This phase corrects product defects (if any) and develops the required new changes.

Features of waterfall model


Easy to use, easy to access. The stages and activities are clearly defined. Validation at each stage, ensuring early detection of defects



It is very difficult to return to a stage once it is over. It has little flexibility and its adjustment range is quite difficult and expensive.

V-Shaped Model

The V-model is today one of the most widely used software development processes . In the V model, the test execution takes place right from the requisition phase. This is also called the verification model and the validation model.


Verification: Verification is a static analysis technique. In testing, this technique is done without having to run the code. It includes several activities such as review, inspection, and walkthrough.


Validation: Validation is a dynamic analysis technique in which testing is performed by executing code. Examples include functional and non-functional testing techniques.



Simple and easy to use. Specific distribution according to each stage. Implement verification and validation early in each development phase.



The adjustment range is quite difficult and expensive. In the V model, development and quality assurance activities are performed concurrently. There is no discrete phase called testing, instead testing is started right from the requirement gathering phase. Verification and validation activities go hand in hand.

Spiral Model – Spiral Model

The spiral model is a risk-driven development process for software projects. Combines the strengths of other models and solves the problems of existing previous models. Based on the individual risk models of each project, the spiral model provides a way to apply elements of one or more treatment models, such as the accelerometer, waterfall model, or model. evolutionary prototyping.

Stages of the spiral pattern

Planning phase: Collect and analyze requirements from the project from the partner side, thereby providing specification documents (Bussiness Requirement Specifications and System Requirement specifications) to serve the exchange between partners later system analysis.


Risk analysis phase: An analytical process will be performed to identify risks and suggest alternative solutions. A prototype will be created at the end of the risk analysis phase. If any risks are found in this process, alternative solutions will be suggested and implemented.


Engineering phase: This is the project phase where developers code, testers test and deploy software on partner websites.


Evaluation phase: The partner will participate in this phase to evaluate the work, the product and ensure that the product meets all the previously set requirements. If there are any change requests, the stages will be repeated.



Estimates of budgets and plans become more realistic as a workflow, because important problems are discovered earlier. Early involvement of the risk manager and phased system development.


High cost and long time to have the final product. Must have good skills for assessing risks and assumptions.

Agile Model – Agile Model

Agile is a set of principles for software development that promote adaptive planning, incremental development, early delivery, and continuous improvement. Agile also advocates rapid adaptation to changes.


Agile does not define a specific method to achieve these, but there are many different software development methods to satisfy and guide those criteria.


The purpose of Agile methods is to help businesses achieve agility, thereby improving competitiveness and sustainable development. Agile methods have changed the face not only in Software Development but are also showing value in other areas such as Marketing (Agile Marketing), education (EduScrum, Lean Edu, etc.), design (Lean). UX, Design Thinking), Lean Startup and Hardware.



Reduce the time it takes to take advantage of some system features. The end result is high quality software in the least possible time and customer satisfaction.



Depends on the skill of the developer of the scalable software.

Scrum Model

Scrum is a “family” in the agile software development process .


This is an agile software development process . With the main principle is to break the software to be produced into small parts for development (these small parts must be independent and releaseable), get customer opinions and change accordingly right in the process. developed to ensure the product after launch will meet what the customer wants. Scrum divides the project into development loops called sprints. It is very suitable for projects with a lot of change and high speed requirements.



One person can do many things for example programmer can test. Detect errors much earlier than traditional methods. Customers quickly see the product thereby giving early feedback. Capable of being applied to projects where customer requirements are not clear at the outset.



The skill of the development team must be high. Must have understanding of agile model. Difficulty determining budget and timing. Always listen to feedback from customers and change accordingly, so the time will be long when there are too many change requests from customers. The role of the PO (Product Owner) is very important, the PO is the product oriented person. If the PO does not do well, it will affect the overall result.
