浅谈SOA架构在企业应用整合中的应用

在构建行业解决方案的过程中,如何能够正确有效地使用企业IT基础架构,使其精密而灵活地配合企业业务需求,是企业成功的关键之一。SOA,即面向服务的架构(Service-oriented Architecture),作为一种软件系统应用架构的方法,SOA把业务组件分成基本的构建模块,就像通过标准化软件接口实现IT基础设施的模块化,从而使灵活的业务流程与灵活的IT流程相匹配,以构建行业解决方案,使企业应用架构能够快速适应变化,实现业务创新和IT增值。本文以SOA面向服务架构为研究对象,首先对其进行了分析,并在此基础上探讨该架构在构建企业应用和整合应用中运用的相关情况。     

解析SUN SOA架构

由于业务流程以及实现这些流程的IT架构都有相当的复杂,企业信息系统转向SOA不可能一蹴而就。SOA的成功一方面取决于企业对于业务核心的理解,另一方面也取决于企业能否形成一个动态的IT架构来适应业务需求变化。在此过程中,需要对业务流程进行广泛深入地分析,正确地形成适应业务流程的服务集合。同时还需要为企业员工提供所需的技能,确保业务与IT两个部门清晰准确的沟通,打破彼此之间的神秘感,从而把业务流程准确地转化为SOA架构。根据企业的目前需求,通往SOA的道路可能应该从小规模起步,以从自身逐渐形成的最佳实践和解决方案框架…

Achieving IT‐based synergies through regulation‐oriented and consensus‐oriented IT governance capabilities

This study aims at exploring the IT governance capabilities that enable organizations to achieve IT‐based synergies. Following existing work on the contextualization of theories and drawing on the resource‐based view of the firm (RBV), we develop an RBV of IT‐based synergies in two steps. First, we adopt existing context‐specific constructs and relationships from prior work on IT governance capabilities, IT relatedness, and synergies to develop a preliminary contextualization of the RBV. Second, to further refine our theoretical framework, we conduct an exploratory field study that includes interviews with 26 CIOs and other IT executives from 21 multibusiness firms. Our findings suggest that IT governance capabilities lead to IT‐based synergies through IT relatedness and business process relatedness. We found regulation‐oriented IT governance capabilities (IT roles and IT processes) to increase IT relatedness, while consensus‐oriented IT governance capabilities (IT groups and relational capabilities) had a positive effect on business process relatedness. Our results suggest that, in isolation, IT and business process relatedness lead to IT cost synergies, while collectively enabling IT‐induced business synergies. Our study is among the first to treat IT relatedness as an endogenous construct and to explicitly integrate business process relatedness into the IT governance domain. Our context‐specific decomposition of IT governance capabilities helps to better explain their links to IT and business process relatedness. These findings contribute to a better understanding of the tension between IT‐based synergies and business‐IT alignment. Decision‐makers are guided in developing IT governance capabilities to achieve IT‐based synergies.     

Aligning the IT portfolio with business strategy: Evidence for complementarity of corporate and business unit alignment

Research on alignment between business strategy and information technology (IT) strategy has generated extensive insights over the last three decades. That research has focused primarily on the fit between business and IT strategies, while cross-domain alignment, i.e., alignment between business strategy and IT infrastructure components, has received far less attention. Further, previous studies have focused on the implications of alignment for firm performance while the effects of cross-domain alignment on business unit performance in multi-business organizations (MBOs) are yet to be examined. This issue is important as IT infrastructures are evolving rapidly. Specifically, MBOs are increasingly turning to corporate IT platforms to support a common set of shared IT needs, while still allowing individual business units to manage unique aspects of their own IT needs through local IT applications. Extending prior research, this study proposes that performance of business units in MBOs is influenced by two complementary forms of cross-domain alignment, viz., alignment between the corporate IT platform and the corporate business strategy, and alignment between the business unit’s portfolio of IT applications and its business strategy. Using data from a global survey of 120 organizations, we find evidence that complementarity between these two forms of cross-domain alignment creates a joint positive effect on business unit performance. We also find that this effect varies with the extent of process digitization within business units. Implications for theory and practice are discussed.

Crafting Information Technology Governance

Information Technology (IT) governance has emerged as a fundamental business imperative, and rightfully so, because it is key to realizing IT business value. IT governance describes the distribution of IT decision-making rights and responsibilities among different stakeholders in the enterprise, and defines the procedures and mechanisms for making and monitoring strategic IT decisions. This article presents a holistic view of IT governance, in which structural, process, and relational capabilities are an integral part of an effective IT governance architecture. the article concludes with an IT Governance Assessment Process (ITGAP) model, with which business and IT executives can assess the effectiveness of their company's current IT governance architecture.

The Effect of IT Governance Maturity on IT Governance Performance

There are several best practice based frameworks that detail effective arrangements for the internal structure of an IT organization. Although it is reasonable that there is a correlation between the quality of the internal structure of an IT organization – labeled IT governance maturity, and the external impact of the same IT organization on the business – labeled IT governance performance, this has not been validated. The results, based on 35 case studies, confirm the hypotheses of a positive correlation between IT governance maturity and IT governance performance. Among IT processes described in 34 references, the internal structure of the IT organization, clearly defined organizational structures and relationships, mature quality management, and cost allocation show the strongest positive correlation to IT governance performance. The maturity of project management and service level management, as well as performance and capacity management, show almost no correlation to IT governance performance. The findings can be used to improve current frameworks for IT governance.
