Outsourcing and acquisition models comparison related to IT supplier selection decision analysis

This paper presents a comparison of acquisition models related to decision analysis of IT supplier selection. The main standards are: Capability Maturity Model Integration for Acquisition (CMMI-ACQ), ISO / IEC 12207 Information Technology / Software Life Cycle Processes, IEEE 1062 Recommended Practice for Software Acquisition, the IT Infrastructure Library (ITIL) and the Project Management Body of Knowledge (PMBOK) guide. The objective of this paper is to compare the previous models to find the advantages and disadvantages of them for the future development of a decision model for IT supplier selection

Implementation of Software Process Improvement Through TSPi in Very Small Enterprises

This article shows an experience in a very small enterprise related to improving software quality in terms of test and process productivity. A customized process from the current organizational process based on TSPi was defined and the team was trained on it. The pilot project had schedule and budget constraints. The process began by gathering historical data from previous projects in order to get a measurement repository. Then the project was launched and some metrics were collected. Finally, results were analyzed and the improvements verified

Comparison of models and standards for implementing IT service capacity management

Due to the recent and significant growth of the information technology (IT) services, industries need some sort of framework and / or standards for the management of their services, especially IT services. So, it becomes necessary and essential to define and adopt a set of best practices for providing and effectively managing the technology and services offered throughout its life cycle. Currently, the management of IT applications and services becomes more complex. Predicting and controlling the problems associated with system performance and capacity planning has become a difficult task. For large IT projects, the costs related to performance tuning, performance management and capacity planning, generally turn out to be the biggest and the most uncontrollable costs. In recent years, a number of frameworks aimed at covering certain issues of IT service management have been developed. One of these issues is the IT service capability management. In this paper, a comparison between the models and standards used today regarding capacity management are presented. A comparison of the strengths and weaknesses of each of the models/standards on the capacity management is presented, so that it can guide organizations to select the model/standard that best suits their needs

Análisis de decisiones en la selección de proveedores de tecnologías de la información: una revisión sistemática

En este artículo se aplica un protocolo de revisión sistemática de Ingeniería de Software para la decisión en la selección de proveedores de Tecnologías de la Información (TI). El objetivo es la búsqueda de documentos relacionados con la toma de decisión en la selección de proveedores de TI. Además, la revisión sistemática se centra en identificar las iniciativas y los informes de la toma de decisión en la selección de proveedores de TI. Los resultados obtenidos demuestran que existe una necesidad de más estudios y definen 16 criterios de evaluación para utilizarse en la selección de proveedores de TI

Un caso de estudio dsobre el control de servicios de TI en una empresa pequeña

This paper shows a case study related to the implementation of the financial management process in a small enterprise whose core business is not Information Technology (IT). A brief description of ITIL v3 financial management process is presented. Then, the target enterprise and its IT infrastructure are described. Finally, it shows how it has begun to implement the financial management process through IT costs accounting of the previous year, which makes the baseline, to make the IT budget for the current year

Mapping CMMI Level 2 to Scrum Practices: An Experience Report

CMMI has been adopted advantageously in large companies for improvements in software quality, budget fulfilling, and customer satisfaction. However SPI strategies based on CMMI-DEV require heavy software development processes and large investments in terms of cost and time that medium/small companies do not deal with. The so-called light software development processes, such as Agile Software Development (ASD), deal with these challenges. ASD welcomes changing requirements and stresses the importance of adaptive planning, simplicity and continuous delivery of valuable software by short time-framed iterations. ASD is becoming convenient in a more and more global, and changing software market. It would be greatly useful to be able to introduce agile methods such as Scrum in compliance with CMMI process model. This paper intends to increase the understanding of the relationship between ASD and CMMI-DEV reporting empirical results that confirm theoretical comparisons between ASD practices and CMMI level

Approach to Identify Internal Best Practices in a Software Organization.

Current approaches to software process improvements (SPI) in software organizations is based on identifying gaps by comparing the way organizations work with respect to practices contained in the reference models. Later, these gaps will be targeted for establishing software process improvements. This paper presents an approach for identifying best practices within the organization. This is considered a key element in order to compare the way software organizations work with the reference models. After that, these practices will be complemented with practices contained in these models depending on the organization's business goals

The Forgotten Practices of Subcontracting.

For many software projects the complexity of the final product has increased to a level where it is impossible to build the whole application from the scratch. So, many organizations consider subcontracting as an option for software development. This paper shows generic problems related to software subcontracting. Also, an analysis of CMMI-DEV subcontracting practices to solve these problems is presented. The review also highlights that there are many critical management practices related to outsourcing to ensure a successful overall project

Introducing IT Ccost Services Management in a Small Enterprise

This papers shows a case study on the implementation of a financial management system related to IT service in a small enterprise whose core business is not IT related. Process models (ITIL is the nost popular) describe "what to do" but not "how to do". Moreover, small non IT enterprises do not the value of IT services provided by their providers the value of the assets underlying the provisioning of those services, and the quallification of operational forecasting. Introducing Financial Management is the Key to connect the business and IT, and in this way, getting opeational visibility, and insight and superior decision making. A case study is presented describing the first steps given in order to introduce IT cost services management, enhancing decision making and obtaining operational control
