Owing to the increased reliance on software applications and the need to evaluate and conduct projects in a timely manner with required results, the Systems Development Life Cycle (SDLC) has become essential to achieving the right products in the requisite period. The military carries out various projects ranging from hardware military equipment to software applications. The paper focuses on the application of SDLC in the military sector. In order to achieve this, secondary research was carried out to get a view of solutions used in the military sector. The authors aim to highlight the common SDLC models and their applications in the military subdivision. This is followed by a review of literature on the militaries’ take on SDLC and the preferred approaches, with a brief look at the Business Capability Lifecycle (BCL). The BCL was noted to be the best SDLC model for military hardware and software applications.

 
 

The paper focuses on the best Systems Development Life Cycle (SDLC) model for military applications in the 21st Century. A review is done on the models used previously and the challenges and success are highlighted. The findings lead to the more recently applied models and the areas in which they are used.

In a bid to better organize the way organizations do business, the SDLC model has been adapted to enhance the quality of required tasks and software applications. This model consists of seven steps, namely, planning, analysis, design, development, testing, implementation and maintenance. These steps describe the methods and strategies required to deliver products that meet client specification and expectations and are also delivered on time.

Various models contain variants of the ones listed. For the purpose of this paper, the authors aim to highlight the Waterfall, Spiral, Big Bang, Agile and the Business Capability Lifecycle (BCL) models respectively. These models provide an overview of a cross-section of the SDLC Models. A brief on the types of projects they are suitable for and benefits and challenges of the models are also explored to give insight into each model. Regardless of what sector projects are being carried out, the basic structure of the SDLC remains the same, allowing for planned procedures to be followed in order to achieve organized project implementation and required product delivery.

The paper looks at the recommendations made by the Department of Defense (DoD) in the United States for better productivity and service delivery of user-specific products and also provides a view of the expectations and considerations of the DoD before embarking on projects. It aims to highlight the potentials and derivative gains of using the SDLC in military applications along with preferred models for possible adoption. These cycles are used in areas ranging from software development and acquisition, embedded systems and also hardware development.
