A Active Systems Development Method Information Technology Essay

Dynamic systems development Method (DSDM) is a agile job management methodology, assessed from Fast Action development (RAD). DSDM consortium (UK) created and retains the DSDM. As the name suggests, DSDM develops the system dynamically. The first version of DSDM was completed in January 1995 and printed in February 1995.

DSDM is a platform for solving intricate tasks. It could be integrated for traditional and agile development method. DSDM platform is modular and strong in aspect. DSDM places itself at the same degree of SCRUM as DSDM handles the small amount of elements of software development. It is iterative and incremental in mother nature. DSDM follows examination and design strategy or the thing oriented way. Main reason for DSDM is to develop software within time and budget limits and with changing requirements.

When certain requirements are not set in the beginning point of development and the machine should be developed in short time then DSDM is very useful. Development starts off with the available requirements and design is developed using those requirements. DSDM solves the normal issues of failures like over budget, exceeding time period limit, less user participation.

DSDM Methodology WITH Primary PRINCIPLES

There are nine basic & most important rules of DSDM

Active user involvement:

This is the most crucial principle of the DSDM. Due to active user involvement error reduces and therefore the mistake cost. In DSDM small group of active user are participating instead of large no. of users.

Empowerment of Team

Due to lack of communication or the resistance in communication between different project stakeholders, the procedure of task development becomes sluggish. To improve the speed of project development some specialist should get to the development team regarding requirements, priorities of requirements and functionalities.

Frequent Delivery

This principle helps to find problems quickly and allows making changes quickly.

Criterion for deliverables is fitness for business purpose

The deliverable should gratify the business needs. So, business requirements is highly recommended first before refactoring.

Nature of development is Iterative and incremental

Project should be divided into small parts or modules to make it simple and easy. It is best for changing requirements. Each module contributes the new feature in the task.

Reversible changes

Dynamic system configurations make system responsive to changing requirements. As in DSDM development is done in small increments, fear of loss of earlier work during opposite process not the problem with DSDM.

High Level Requirements

Some of the requirements should be placed at higher level such that it can be improved easily in the later stages of development.

Integrated Testing

In DSDM testing is included from first stages of development process to the end of the development method.

Co-operation and collaboration of all stakeholders in development method must collect all requirements also to get proper review on the software developed.


For the success of the DSDM there are a few pre-requisites to be studied in to thought. There software is usually to be divided in to small parts and developed usig iterative and incremental strategy. There must be good communication between development team, management and end users which solves the issue of insufficient communication and end-user participation.

There are some cases where DSDM is not considered as a good way. One, when the job is highly safe and critical and other is the task which includes re-usable components. Reasons for why DSDM is not good for above projects is that DSDM stresses on fast delivery within time n budget constraints so high evaluation and validation methodology for above project is not accompanied by DSDM. Second reason is, DSDM will not produce job perfect first-time.


There are three basic phases of DSDM

5. 1 Pre-Project (Period -I)

In this phase candidate task, budget of task and dedication is analyzed to reduce errors within the next phases.

Project Life Cycle(Phase-II)

This is the main stage of the DSDM. Relating to DSDM process the project is developed in incremental and iterative manner. There are total 5 stages in this phase. Each level is described below at length.

Feasibility Study

In this stage, study is performed to identify that DSDM is useful for the task or not? If DSDM will satisfy all the business enterprise and functional need of the job or not? Feasibility analysis is completed for the task which includes risk factors, planning, prototype, feasibility statement.

Business Study

It is expansion of feasibility review. In this stage, business aspects of the project are taken into consideration. Different stakeholders meet to go over the job. This level includes expanding prototype, list of requirements by priority, development plan and other released related to business. Priorities of requirements are made a decision using MoSCoW strategy.

Time Boxing technology is used in development plan. Desired quality is achieved by using this technology. There's a risk log consisting of all the risks during DSDM is developed

Functional Model Iteration

Functional model is created by converting the requirements. Prototype is very important technique through which user involvement is noticed throughout the project. Different users review the developed prototype. Iterations are completed to enhance the quality of software. You will find four sub-stages as follows:

Identify Functional prototype:

Identify the functionalities that are executed in the prototype.


A schedule is to be chose for when and exactly how to develop functionalities.

Create Functional Prototype:

The prototype is developed, looked into and sophisticated and combined with prior iteration of useful prototype.

Review Prototype:

A review record is established from evaluation and by firmly taking reviews of customers.

Finally, the practical prototype and model along delivered which includes all the functionalities. The requirements which are believed in past iterations re erased from the priority list. Risk log is also created.

The main concentrate of this level is to create and build the prototype to complement the business needs. These prototypes are processed until it reaches to a typical.

Testing is important part of the stage also. Here, the functional and non-functional requirements are identified and examined. Design prototype is examined by the end use and then shipped and passed to another stage i. e. execution.


This is the final level of the DSDM. Some possible situations with this level is that end user requirements are satisfied efficiently, so no dependence on development or get back to business study stage and add new discovered functional requirement or due to time limitation the less important missed part of job is added by going back to efficient model or to gratify some non-functional need go back to design and build iteration level.

DSDM follows iterative methodology. Therefore, the job or the software will not be perfect for the very first time but involve some of the useful functionalities. Iterative methodology is very useful where resources and time is permanent or limited and requirements are changing. End user tests the machine and agrees for the execution. If certain requirements are met or not corresponding to that the projects goes into next period or the prior phases as mentioned above with four possible conditions. User-guide or an individual document is established. Project or the program and the record are delivered after this phase.

Post-Project ( Phase-III)

Errors or any problems are set in line with the DSDM guidelines. As DSDM is incremental and iterative in dynamics so refinement and maintenance is carried out on continuous basis. In this stage correctness and performance of the project is inspected.

How DSDM deals with (if possible)

Timeboxing technique is utilized during development to consider issues like time, budget and quality. Main idea of timeboxing is to separate the software into small parts with preset delivery time frame and budget. As, time and budget are limited if the job exceeds its deadline then your requirements with less concern is not considered. Such as DSDM the software is not developed properly first time only certain requirements with highest top priority is taken in to thought also DSDM is iterative and incremental in mother nature, each iteration processed the prior iteration and improves the quality of the program.


It is technique to prioritize things. Here, it is utilized for prioritizing requirements.

"M-Must have this requirement to fulfill business needs. "

"S-Should have this requirement if at all possible, process is not reliant on this necessity"

"C-Could have this necessity if it does not affect the quality of the business enterprise needs of job"

"W-Would have this requirements at later stage if a while is left"


The Prototyping is vital technique of DSDM. It handles the creation of prototype in the early phases of development method. Using prototype, users become familiar with about how the system will be or an overview of system.


This approach ensures good and satisfactory quality of the software. In DSDM, testing is completed throughout the development method which enhances the grade of the finish product. Testing technique vary will depend on the development team.


This technique is utilized to gather all the stakeholders for conversation of project. Talk addresses issues related to requirements, functionalities and quality and time


Modeling Technique is utilized to create a style of the project being developed for the better visualization of the business enterprise aspects of job.

Configuration Management

As DSDM is active and iterative in character so delivery is fast and regular. To handle each one of these iterations and deliverables configuration management is needed which really helps to implement the software or system in good manner.


There are some jobs and obligations associated with roles which are important in DSDM. Functions and duties should be given before development routine starts.

Executive sponsor handles resources and cash and also offers power to take decisions. Visionary is accountable to make sure that requirements are located at the early level of development. Visionary is aware of the business needs perfectly. He also supervises the development process. Ambassador user is the individual who deals with the users and brings their requirements and responses to project development team. Consultant user is an individual who deals with the point of view of project. Job manager handles the task.

Technical Coordinator is in charge of design, architecture and quality of system. Team Innovator leads the team and make sure that team works effectively. Developer creates prototype and develops the system in line with the requirements. Tester is accountable for quality of the system and he makes a decision which testing strategy should be employed. Scribe is accountable to collect the requirements. Facilitator is in charge of communication between different stakeholders. There are a few special jobs are also there like Quality Manager, Business Architect, etc.

Generally, DSDM project includes a couple of groups. One team is responsible for development of the program while other is accountable for testing the program. Usually, each team consists of more than 5 people. In case the project or the software to be sent is large then more groups required. When the software or a job is large then the quality becomes the essential aspect. So, it is recommended that developers should not do evaluation and there should be a separate trials team.


Key Success factors of DSD includes iterative and incremental characteristics, fast and regular delivery of project, participation of management and end-users, some decision making electricity given to productive users, size of the team, no change with time and budget limitations. All of these factors are essential and helpful for the success of DSDM.


DSDM has many advantages which make it a good development technique. Using DSDM task development can be started immediately after requirements are obtained. Delivery of the machine becomes fast and within time and budget limitations. DSDM improves the efficiency. Iterative characteristics of DSDM improves the product quality.

Management is actively involved which helps to make the important decisions faster and thus the development process become faster. Consumer involvement is vital advantage. User participation makes requirements clear and feedbacks makes system better. Better Quality project produced using DSDM as the evaluation is carried out throughout the development method. Good design and good documentation is one of the features of DSDM.


As DSDM is not so common, it is not easy to understand. In first iteration the system might not be perfect. Because of prioritization of requirements, requirements with less priority are overlooked. Time and budget is fixed so a few of the requirements may be omitted.


Thus, DSDM can be an agile strategy for projects which are bound by the time and budget constraints. When
