The project manager is responsible for managing all aspects of the project; this includes software application development, hardware, and network acquisition/readiness, as well as oversight of the interface and conversion tasks. The project manager must possess good communication, facilitation, organizational, and motivational skills when leading a successful implementation. A sound knowledge of healthcare delivery, regulatory requirements, and hospital culture, processes, and politics is essential. SDLC assists with process development, change management, user experience, and policies in addition to technical aspects of system development. An SDLC also provides for planning ahead of time, determining expenses and staffing decisions, defining goals, measuring performance, and validating points at each stage of the cycle to improve the final product’s quality. The systems development life cycle (SDLC, also called the software development life cycle or simply the system life cycle) is a system development model.
- It also captures the structure in which these methods are to be undertaken.
- Before creating a product, a core understanding or knowledge of the product is very necessary.
- You will understand what an SDLC is, the 7 stages of the system development life cycle, and why it is vital by reading it.
- A long-standing notion in the wide world of IT, a system development life cycle, or SDLC, is an iterative process that incorporates numerous activities that constitute the development of a structured information technology system.
- For example, testing may involve a defined number of end users and use case scenarios in order to be deemed successful, and maintenance may include quarterly, mandatory system upgrades.
Database design is the second phase focusing on the design of the database that supports company operations and objectives in the future.

Each phase has its own mini-plan and each phase “waterfalls” into the next. The biggest drawback of this model is that small details left incomplete can hold up the entire process. In other words, the team should determine the feasibility of the project and how they can implement the project successfully with the lowest risk in mind.
Software Requirement
Not just limited to purely technical activities, SDLC involves process and procedure development, change management, identifying user experiences, policy/procedure development, user impact, and proper security procedures. Books such as David Avison and Guy Fitzgerald’s Information Systems Development and Alan Daniels and Don Yeates’ Basic Systems Analysis, delve into the intricacies of information systems development lifecycles. This article will provide an in-depth analysis of the history, definition, phases, benefits, and disadvantages, along with solutions that support the system development life cycle.
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. In addition, governance and regulations have found their way into technology, and stringent requirements for data integrity impact the team developing technology systems. Regulations impact organizations differently, but the most common are Sarbanes-Oxley, COBIT, and HIPAA. Completely defined in 1971, the term originated in the 1960s when mainframe computers filled entire rooms and a pressing need developed to define processes and equipment centered on building large business systems. In those days, teams were small, centralized, and users were ‘less’ demanding.
Aligning to the SDLC
This type of scenario meant that there was not a true need for refined methodologies to drive the life cycle of system development. However, technology has evolved, systems have become increasingly complex, and users have become accustomed to well-functioning technology. Models and frameworks have been developed to guide companies through an organized system development life cycle.
An extension of the waterfall model, this SDLC methodology tests at each stage of development. Popular SDLC models include the waterfall model, spiral model, and Agile model. The waterfall approach means each phase must be completed before the next phase can begin. During these phases architects, developers, and system development life cycle phases product managers work together with other relevant stakeholders. Technology has progressed over the years, and the systems have gotten more complex. Users have gotten used to technology that simply works, and various methods and tools ensure that companies are led through the lifecycle of system development.
Project Managing the System Development Life Cycle
For example, define a nomenclature for files or define a variable naming style such as camelCase. This will help your team to produce organized and consistent code that is easier to understand but also to test during the next phase. Also, make sure you have proper guidelines in place about the code style and practices. This article will explain how SDLC works, dive deeper in each of the phases, and provide you with examples to get a better understanding of each phase.
The project scope document becomes the internal organizational contract for the project. These phases include database primary study planning, analysis, detailed System design, (prototyping), implementation and loading, testing and evaluation, operation, maintenance and evolution. In the database primary study, the researcher examines the current systems operations in the company to determine how and why the current system isn’t sustainable.
Management Notes
As the SDLC is a repetitive methodology, you have to ensure code quality at every cycle. Many organizations tend to spend few efforts on testing while a stronger focus on testing can save them a lot of rework, time, and money. These can be solved during the maintenance phase when the whole system is refined to improve performance, or to meet new requirements.
Design documents typically include functional hierarchy diagrams, screen layouts, business rules, process diagrams, pseudo-code, and a complete data model with a data dictionary. These elements describe the system in sufficient detail that developers and engineers can develop and deliver the system with minimal additional input. During this step, current priorities that would be affected and how they should be handled are considered. A feasibility study determines whether creating a new or improved system is appropriate. This helps to estimate costs, benefits, resource requirements, and specific user needs. During this stage of the system lifecycle, subsystems that perform the desired system functions are designed and specified in compliance with the system specification.
Quality management and System Development Life Cycle
Report on key metrics and get real-time visibility into work as it happens with roll-up reports, dashboards, and automated workflows built to keep your team connected and informed. Fundamentally, SDLC trades flexibility for control by imposing structure. It is more commonly used for large scale projects with many developers. At this step, desired features and operations are detailed, including screen layouts, business rules, process diagrams, pseudocode, and other deliverables. Team members may change during the course of a 10to 16-month implementation. Hospital leaders, visionaries, and change agents’ participation must balance the pragmatic bottom line dictated by organizational needs (e.g., Promoting Interoperability incentives vs. patient outcomes).
Most solution providers use the waterfall life cycle approach for software solution development. The waterfall approach (refer Figure 14.3) helps to understand the extent of the residual risks and allows one to work conscientiously toward reducing those risks. When teams develop software, they code and test on a different copy of the software than the one that the users have access to. The software that customers use is called production, while other copies are said to be in the build environment, or testing environment. This step involves decomposing the system into pieces, analyzing project goals, breaking down what needs to be created, and engaging users to define requirements. Relevant questions include whether the newly implemented system meets requirements and achieves project goals, whether the system is usable, reliable/available, properly scaled and fault-tolerant.
Software project management
Each SDLC model offers a unique process for your team’s various project challenges. The project’s specifications and intended results significantly influence which model to use. For example, the waterfall model works best for projects where your team has no or limited access to customers to provide constant feedback. However, the Agile model’s flexibility is preferred for complex projects with constantly changing requirements.
