Software Project Management Introduction
Published in Marvin Gechman, Project Management of Large Software-Intensive Systems, 2019
The System Life Cycle is a cradle to grave perspective starting with an initial conceptual analysis of the proposed system and ending with an ultimate replacement or retirement of the system. The SLC is sometimes referred to as the “System Acquisition Life Cycle.” Figure 1.2 should be carefully reviewed as it is an important conceptual overview involving the hierarchical relationship of: The System Life Cycle that includes System Definition, Software Development Life Cycle and the System Sustainment activitiesThe Software Development Life Cycle which incorporates part of System Definition, plus the Software Implementation Process and the System Integration, Testing and Verification (System IT&V)

The software test-and-fix cycle (TaFC) is a case of the rework cycle in which software defects introduced during specification, design, and implementation have not been discovered as the product enters testing. Despite advances in software development processes, the TaFC remains a development phase of central importance for complex software-reliant systems. In extreme cases, lack of quality-inducing effort prior to software or system integration testing produces poor-quality software and leads to a lengthy test-and-fix (TaF) phase.
Simulation and Emulation
Published in Kim H. Pries, Jon M. Quigley, Testing Complex and Embedded Systems, 2018
If we build a full-scale simulation environment using an advanced software tool like Matlab/Simulink, we can continue to use that tool when performing early system integration testing, where we may not have all the hardware for the new system. We can use the tool to drive what hardware we have and use the rest of it to simulate signals and other electrical and electronic data. The primary benefit is that we do not have to wait for a full set of hardware to begin our testing and designed experiments.

The project phase is where the system is up and running. Key players such as the project manager, IT specialists, and vendors engage in key activities including software configuration, system integration, testing, data conversion, training, and rollout. A myriad of issues could arise in this phase including a lack of required knowledge and expertise of teams, insufficient change management, underprepared data conversation, and insufficient financial support.
