Application Lifecycle Management (ALM) has a history of research related to software development processes and productivity over the last 40 years. Recently software has penetrated into almost every industry, thus every company is a software company now. Parallel to the history of ALM process models, at first it was considered synonymous to waterfall. However with the questioning of the success...

The spiral model, illustrated in Fig. 1.7, combines the iterative nature of prototyping with the controlled and systematic aspects of the waterfall model, therein providing the potential for rapid development of incremental versions of the software. In this model the software is developed in a series of incremental releases with the early stages being either paper models or prototypes. Later it...

In this paper we look at a number of approaches for modeling the system acquisition process. Beginning with the waterfall model of Winston Royce, we continue with derivation that includes more intricate and detailed waterfall models with feedback, including the “V” and spiral models. In addition we look at several acquisition strategies. In reviewing the various models we discuss our view that ...

This paper proposes a Human-centered Pervasive Computing System Model (HPC), a Layered Architectural Analysis and Design Method (LAAD) and a Waterfall Prototyping Process Model (WPP). Based on the HPC model and the LAAD method, a pervasive computing based multimodal tele-home healthcare system is designed and partly implemented using the Waterfall Prototyping Process. The design and implementat...

In this paper, we investigate the potential of the Boyer-Moore waterfall model for the automation of inductive proofs within a modern proof assistant. We analyze the basic concepts and methodology underlying this 30-year-old model and implement a new, fully integrated tool in the theorem prover HOL Light that can be invoked as a tactic. We also describe several extensions and enhancements to th...

Imagine that you are in the market for some custom software. You’ve issued an RFP, prohibited any contact between bidders and your organization, and demanded a single price for the whole effort. In response, one of the prospective contractors pitches you the following scenario. “For US$35,000,” the contractor’s account executive says, “an cross-functional team of our best people will work with ...

Given recent observational results from the BICEP2 and Planck collaborations regarding the ratio of power in tensor to scalar modes in the cosmic microwave background radiation, and the implications of this ratio for the possible existence of large gravity waves resulting from inflation, it is of current interest to investigate models of inflation which are capable of producing large gravity wa...

Waterfall development is still a widely used way of working in software development companies. Many problems have been reported related to the model. Commonly accepted problems are for example to cope with change and that defects all too often are detected too late in the software development process. However, many of the problems mentioned in literature are based on beliefs and experiences, an...

The paper explains and clarifies the differences between Waterfall and Agile development methodologies, establishes what criteria could be taken into account to properly define project success within the scope of software development projects, and finally tries to clarify if project success is the reason why many organizations are moving to Agile methodologies from other ones such as Waterfall....

Our team helps Tieto teams distributed over the entire world to set up effective way of working applying Agile, Lean, Kanban and Global sourcing principles. In May 2009 we have faced our biggest challenge. Energy sector product, 30 people in Norway, Sweden and Finland with waterfall way of working organized into regular 6 sub-applications wanted to achieve quite challenging targets. To grow to ...
