Exploiting organizational knowledge in developing IS project cost and schedule estimates: An empirical study

Project management is vital to the effective application of organizational resources to competing demands within and across projects. The effective application of project management, however, is predicated upon accurate estimates of the project budget and schedule. This study assesses primary and supporting activities that exploit knowledge within an organization's memory to develop project schedule durations and budgets. The study further assesses the subsequent impact of predictability on project success. Two hundred and sixteen survey responses from IT professionals with project management responsibilities were analyzed. Results found use of the primary activities of using parametric estimating techniques (use of formal models), bottom-up estimating techniques (formulating estimates at the task level), and the support activities of team reliance, realistic targets, and professional experience all impact the predictability of estimates for project cost and duration. Predictability in turn was found to directly impact project success with regards to meeting cost and duration objectives. While use of analogous estimating techniques (using similar previous projects) was not found to be useful for project managers with more experience, it was used by project managers with less experience in determining predictability.     

基于BIM 和挣值法的地铁车站5D 应用探讨

目前地铁工程在我国发展迅速,许多大中城市有建设地铁的需求。地铁工程成本 大、工期紧,优化进度和成本联合管理是非常必要的。BIM 技术由于其特有的优势,其在工程 项目中得到不断的研究和应用。但目前在地铁工程中,BIM 主要应用于模型建立、检查碰撞、 施工模拟等方面,在其他方面的应用研究还较少,并且各方面的应用相互独立。基于BIM 技术, 根据进度-成本的综合管理方法——挣值管理方法对某地铁车站工程进行3D+进度+成本的综合 施工管理应用,实现了施工过程的可视化管理以及进度和成本的跟踪管理,评估项目的实际实 施情况并及时调整,为计划的完成提供保障。拓展了BIM 技术在地铁工程中的应用,尝试了 BIM 技术在地铁工程中的综合管理应用。     

A new framework for managing IT-enabled business change

Abstract. Although information systems and technology (IS/IT) investments have always caused varying degrees of business change, the main purpose of many of today's IS/IT implementations is to change the business and/or organization in some significant way. However, most organizations' approaches to managing IS/IT developments have changed little in the last 15–20 years and are heavily dependent on methodologies of IS/IT development and associated project management principles. The philosophy being adopted by many organizations today is that there are few IS/IT projects (some infrastructure investments only) that do not cause business changes and therefore they are really 'business projects involving IS/IT'. This exploratory research set out to devise a new framework for 'IT and change' management, which is more appropriate to today's realities than traditional approaches. The initial framework was derived from 'first principles', then adapted and further developed by applying and testing it in a range of real projects in organizations. This paper summarizes the results of that work.

Complementary Investment in Change Management and IT Investment Payoff

Measuring information technology payoff continues to be a challenge for organizations. Considering the impact of complementary investments on IT payoff has been proposed by recent studies. This paper examines the impact of one type of complementary investment on IT payoff: organizational change management initiatives to support IT implementation. The paper reports a case study of Cisco Systems' IT investment in an operating systems upgrade of over 34,000 computer systems in 117 countries. The findings of the exploratory case study indicate that planned communications and change management strategies developed by their Organizational Change Management group led to the smooth implementation of the upgrade process and contributed to the payoff from the IT investment, measured in terms of client satisfaction with the process and system and reduced cost and time to upgrade all systems. The findings were supported by pre- and post-implementation surveys of clients, analysis of the change management initiatives and their impact on the process, and comparison of actual and budgeted costs for the project.

Management of lifecycle costs and benefits: Lessons from information systems practice

Assessing the economic feasibility of information systems (IS) projects and operations remains a challenge for most organizations. This research investigates lifecycle cost and benefit management practices and demonstrates that, overall, although organizations intend to improve their information technology (IT) management, they squander many opportunities to do so. There are inconsistencies in cost/benefit management practices. Most organizations that integrate operational benefits into investment analyses do not acknowledge operational costs. Planned project goals are seldom formulated in a verifiable or measurable way; there is little structured feedback on individual lifecycle activities, nor co-ordination of various activities. Thus, the attitude towards cost/benefit management appears primarily context-related and incident-driven. A further development of the system lifecycle-based approach is needed to improve IT cost/benefit management theory and practice, because a coherent set of methods is required to assess IT costs and benefits throughout the entire lifecycle.     

Knowledge-based risk assessment and cost estimation

A knowledge-based method for software project risk assessment and cost estimation has been implemented on multiple platforms. As an extension to the Constructive Cost Model (COCOMO), it aids in project planning by identifying, categorizing, quantifying and prioritizing project risks. It also detects cost estimate input anomalies and provides risk control advice in addition to conventional COCOMO cost and schedule calculation.The method has been developed in conjunction with a system dynamics model of the software development process, and serves as an intelligent front end to the simulation model. It extends previous research in the knowledge-based cost estimation domain by focusing on risk assessment, incorporating substantially more rules, going beyond standard COCOMO, performing quantitative validation, providing a user-friendly interface, and integrating it with a dynamic simulation model.Results of the validation are promising, and the method is being used at Litton Data Systems and other industrial environments. It will be undergoing further enhancement as part of an integrated capability for software engineering to assist in system acquisition, project planning and risk management.
