These various aspects are used to create a workflow pipeline, a sequence of steps that when followed produce high quality software deliverables. This pipeline is known as the Software Development Lifecycle. The art of software development has many deep schools of thought.
The following discussion is not a comprehensive guide, but a overview of the most recognized techniques. Software development today is generally executed with a complementary agile project management process. This process is in-effect during steps 3 and 4 from the Software Development Lifecycle. A regular planning period is conducted in which expectations are set, dependencies are addressed and tasks defined.
The tasks are executed and adjusted during a sprint period. During the sprint period these tasks are updated as they progress to completion. Specialized organizational software for task tracking, like Jira, is used to monitor the state of individual task within a holistic sprint view. Concept Projects are envisioned, designed, and prioritized. Confluence is a great tool to develop product research documents and share design files during this stage. Design documents from the concept phase are broken down into actionable tasks.
Jira and Trello manage, track, and organize these task lists. The live production code will need a place to live. IT Support Support and maintenance is required of active software projects. Jira Service Management provides powerful tools to capture, triage, and resolve customer support requests.
Incident Management Deprecation and end-of-life activities, including customer notification and migration are software development best practices. Confluence is a great tool to develop Product research documents and share design files during this stage.
Design documents from the Concept phase are reviewed and broken down into actionable tasks. Jira and Trello are used to manage track and organize these task lists. Bitbucket offers code review tools which encourage iterative quality improvement through team discussion. IT Support Ongoing support and maintenance is required of active software projects. Jira Service Desk provides powerful tools to capture and triage support requests.

The immediate future of software development is directed by a few core values: automation, transparency, and democratization. Overall these trends are lowering the costs required to develop new projects and lowering the barrier to entry for non-technical team members to contribute to software development.
The following practices have been adopted by some of the most successful enterprise software companies. Understanding how your team can use these practices to increase the speed of development can lead to a competitive advantage. These are the trends and practices that are enabling software companies to execute next level vision and delivery of product. Before feature flagging, teams would push entire features out to all production users as part of a regular code release.
Feature flagging reduces the risk for deployments by allowing safe validation of features in a production environment before exposing them live to all live customers. Once a feature flag rollout has been successfully, privately, validated it can be rapidly rolled out and change live customer experience. Many modern networked applications have adopted a Microservices architecture MSA infrastructure. MSA is a distributed network architecture that enables horizontally scaling and network redundancy.
A microservice implementation will break an application in to separate deployments that correspond to business needs. Some examples of these business needs are: payments, authentication, and analytics.
A reemergence of lost and under utilized functional programing paradigms from the last century is underway. A new generation of developers are rediscovering languages like Ocaml , Haskell , and Lisp. Discussions are being had about mistakes in language design. Discussions like maybe Object Oriented Programming was a mistake. Organizations are finding that higher quality, well designed, user empathetic programing languages can lay a foundation for higher quality, well designed user empathetic business product output.
Functional languages can provide these higher quality offerings with features that lower the cognitive overhead of developers interacting and maintaining a code base. This leads to less bugs and higher quality software. Formal verification is the process of proving or disproving the correctness of algorithms in an underlying system.
It can be thought of as a mathematical process like verifying an algebraic expression. A formal property specification is provided for the algorithms implementation, and methods like static analysis can be used to prove the correctness of the implementation. From the idea of formal verification comes the radical idea that—maybe—code can write itself. Given a well designed up front formal business domain type specification and a soundly typed language. Generative tools can be used to write a code base that matches the formal specification.
Languages like idris , coq , agda are exploring these ideas. Continuous integration and Continuous development , are the premier examples of the value of automation.
Teams would have to collaborate and sequence when to merge features and think about avoiding conflicts in code updates between team members. Deployments were risky affairs where teams would manually copy files between servers and the network could fail or desync a deploy across a cluster. Outcome driven development is a workflow process that encourages rapid, lightweight software development. ODD defines goals instead of tasks and assigns ownership of those goals to a team which will be responsible for meeting that goal and implementing.
Once the charter has been approved and signed-off by all key project stakeholders , the project starts. Next comes the Planning phase, where the team works together to formulate the project plan. One of the key outputs from project planning is the project deliverables. These are the items the project will deliver, which could range from new software products to patches.
Another important element of planning is defining the criteria that will be used to measure project success. Widely used success criteria for software projects include quality targets and whether the project was delivered on time and on budget.
Basically, what exactly will make the project a success? Once your deliverables and success criteria are lined up, you can move on to planning the activities that make up the project work. Elements of this planning process include:. Specifying project milestones , which represent key landmarks on the journey to project completion. Identifying dependencies between tasks, where completion of one task depends on another task being completed first.
The Execution phase of a software project spans the active work of the software development process. This, as all developers know, represents a further series of processes including design, development, testing and quality assurance QA tasks. This work should be completed through your chosen development workflow. The role of project management throughout the execution phase is largely focused around project monitoring. In the final phase of the project cycle, software teams should meet up either face-to-face or digitally and jointly evaluate the project.
Ask yourselves: what worked really well, what let us down or held us back, and were there any learnings that can be fed directly into planning for the next project?
In some project management methodologies , this process of evaluation is facilitated through meetings called retrospectives. Software development projects are often managed according to agile project management principles. This makes a lot of sense, given the fact agile was invented by software developers. Agile is a set of principles which form the basis of leading project management methodologies such as scrum and kanban.
It underpins the thinking behind most contemporary project management processes. According to Agile Alliance, the agile approach can be broken down into the following principles:. People on the business and development sides of the team should work together closely, day-to-day.
Paying heed to these principles usually proves to be a wise move for software development teams, so we recommend you build all 12 into your project management process. Agile project management was gradually pieced together by software engineers, in the latter decades of the 20th century. Today, all manner of teams use it to deliver their projects, including government departments, creative agencies , web developers and, of course, software engineers.
We have no doubt software engineers will long continue to use the project management principles their own profession created to build useful things for the future. Therefore the term includes, but is not limited to, desktop applications, or mobile apps, embedded software controlling machines and devices , and websites. Software applications, whether developed in house or by a partner or vendor, are of critical importance in the delivery of customer value in technology-enabled business services.
As a result, software development and management is a key practice in every modern IT organization, ensuring that applications are fit for purpose and use.
