Get Maximum Benefits of Merging Top-down and Bottom-up Project Management
Combining Top-Down and Bottom-Up Segmentation - IEEE Conference Publication
Our research project develops an intranet search engine with concept-browsing functionality, where the user is able to navigate the conceptual level in an interactive, automatically generated knowledge map. This knowledge map visualizes tacit, implicit knowledge, extracted from the intranet, as a network of semantic concepts. Inductive and deductive methods are combined; a text analytics engine extracts knowledge structures from data inductively, and the enterprise ontology provides a backbone structure to the process deductively. In addition to performing conventional keyword search, the user can browse the semantic network of concepts and associations to find documents and data records. Also, the user can expand and edit the knowledge network directly. As a vision, we propose a knowledge-management system that provides concept-browsing, based on a knowledge warehouse layer on top of a heterogeneous knowledge base with various systems interfaces.
Nowadays, the bottom-up approach to management is becoming more and more popular. More and more, organisations are abandoning the top-down management style. Even the world biggest corporations, such as Toyota and IBM, are trying to implement bottom-up management style elements in some of their departments. However, managers are still arguing over which approach is more beneficial for organisations. To understand the reason for the ongoing changes in management processes, we need to compare the two management styles.
