Project management is a methodical approach to planning and guiding project processes from start to finish. According to the Project Management Institute (PMI), the processes are guided by five stages: initiation, planning, execution, control and closure. Project management can be applied to almost any type of project and is widely used to control the complex processes of software development projects.

Introduction to the Internet of Things (IoT) for IT Managers
The Internet of Things is changing the way we connect, communicate and do things. Read our introductory guide to how this technological breakthrough will impact companies, and how to prepare to support the technologies linked to IoT.
The Systems Development Lifecycle (SDLC) is an example of a methodology to guide the project management process from a first feasibility study to the maintenance of the entire application. Various SDLC approaches include the cascade model, which was the original SDLC method; Rapid application development (RAD); Joint application development (JAD); The source model; Spiral model; Build and repair; And synchronize and stabilize. A number of graphical methods, such as the Gantt chart and the PERT table have been developed as tools to create a graphical representation of a project plan and its current state.
Pert / CPM, partners in project management
Pert is one of the most used methodologies for managing projects, especially since it usually acts as a complement to CPM and Gantt Diagram. This technique consists of:
Determine the activities in which the project is broken down, its dependencies and duration to apply a probabilistic function to help calculate the total execution time based on an optimistic, pessimistic or normal perspective that, together, determine the estimated time for each activity .
With the data obtained, a mesh composed of nodes can be designed to determine the critical path and its standard deviation, as well as the variance for each activity.
This methodology is very practical when the project combines activities that are executed sequentially and in parallel.
