This paper explores what kinds of management actions are needed by businesses to enhance their innovation capabilities. The first step is to clarify the differences between information and knowledge. To do this, the author introduces a model that can explain an individual's mental processes in knowledge acquisition and creation. With this model, it becomes explainable in a comprehensive way how "explicit" knowledge received as information is turned into individual knowledge; how "tacit" knowledge can be successfully transferred between workers; and how new knowledge can be created by individuals. The model assumes that knowledge workers can be classified into two categories, i.e., Type-1 and Type-2. A Type-1 knowledge worker is one whose knowledge acquisition depends almost exclusively on learning. A Type-2 worker is one who has a substantial amount of self-created knowledge in addition to learned knowledge. It is quite common to find Type-1 workers, but there are not that many Type-2 workers. Successful business firms are usually led by Type-2 workers, who are more innovative. In order to enhance the innovation capabilities of business firms, rather than waiting for the fortuitous advent of Type-2 workers, management should make an effort to transform existing Type-1 workers into Type-2 workers. The author makes the assertion that such a transformation is possible by putting Type-1 knowledge workers into situations where their "insight for knowledge creation" is constantly stimulated. Constant stimulation is made possible by using an IT system based on the Timed-PDCA concept that was proposed by the author in his previous papers. When this system is deployed seriously by management, it becomes possible to facilitate workers' breakthrough efforts and to promote close collaboration among workers through information sharing and visualization. © 2014 Elsevier B.V.

Corporation is operated based on the strategy for having an enterprise to be sustainably growing. The workers who are employees and managers run several tasks simultaneously based on the workflow reflected on their experience and knowledge. Such workflow's tasks affect each other interactively due to invocation of an interrupt. When the multiple workflows are overlapped, the continuity of the active task is interrupted. The evaluated interruption invokes positive or negative effect according to the context of the tasks. In this paper we discuss the attributes of the tasks interruption, to provide an assistance in resuming or sustaining (i.e., interrupted) task work from interruption by the system to achieve suistabanle workflow and possible optimization. © 2012 Springer-Verlag.

In this paper, using an application software system called "sales funnel" is proposed to improve sales force performance measurement and training for B2B business. With this software, updating prospects' information weekly at the origin by sales representatives, allows real time sharing of information throughout a corporation and visualizing the entire sales process. This reduces data preparation time before corporate level strategic discussions. Enforcing weekly updates by this system results in time shortened PDCA (Plan, Do, Check, and Act) cycles, thereby enabling the acceleration of the sales activities. Moreover, repeated PDCA cycles with enforced logical thinking, gives essential on-the-job training to the sales representatives, nurturing them into becoming better performers.

There is a popular function that can display the target object to full screen in using computer. This function has a feature that many contents on last active object are hidden by the other object when the user switches the active object to the other object. Therefore, the resource for thinking is consumed by keeping the memory of the hidden information. In this paper, we propose three ideas for keeping the display of contents on active object below. One is an idea that is keeping the desired object to front side of the screen. The other idea is to list files while displaying the active object. And to set automatically the size and position of object to the frequently used size and position file by file. In addition this paper describes how to apply the above ideas to the control-icon that can easily handle multiple objects and was proposed by the authors' previously.

A new data management method called ISSEI was proposed in the previous report [1], to avoid slowing down of data retrieving time for the database that has an inherent nature of ever growing data volume. ISSEI's data handling performance, namely adding, retrieving, updating and deleting data were evaluated. Through the evaluation, it was confirmed that ISSEI's data handling performances are not dependent on the database size, while the conventional DBMS such as MS SQL Server requires more time for data handling as the database size grows [6].This paper deals with evaluations of ISSEI's performance limitation on system operation and maintenance toward applying ISSEI to a corporate knowledge database that has growing data volume. Through the evaluations, interesting results were obtained. One interesting result is that ISSEI's performance dependency on the data volume size is maintained up to the upper capacity of hard disk. Another interesting result is that data recovery performance of ISSEI is drastically degraded by the length of data records. From the two results, it is concluded whether ISSEI can be applied for the database that has growing data volume or not.

Decision making of worker for appropriate task selection based on workflow is often changed by occurring interruption. Pre-assignment by superior decision maker is one of criteria for the task selection. Expected task achievement by pre-assignment is changed by occurring interruption due to inserting external activity to the worker. Interruption consumes usable time for the current workflow by operating generated new task. The concerned workers of interrupted workflow must optimize workflow to improve consumed time of current tasks by changing engagement of assigned tasks. Proposed approach in this paper improves the changed achievement of tasks in certain interruption by applying meta-heuristic approach. © 2013 IEEE.

Knowledge management system (KMS) should handle efficiently a large information that is in most cases is related to user experiences and related situation that can affecting the performance of these KMS. User usually is keen to looking for the knowledge that fits best in his situation and domain work that instantaneously is changing due to handling situation. This outline presented in this paper facilitates the necessary detection of knowledge discovery that fit in the current problem solving, by estimating the user situation model along with user profile as a coherent model that reflects on the knowledge base in transparent manner. This would participate in determination of the best fitness of work flow that represents a semantic alignment between user profile and knowledge as pair-wise representation for optimized workflow that can participate to reflect a better performance in relation to semantic integration of user model and related knowledge.

This paper deals with the productivity improvement of knowledge work. The productivity of knowledge work is improved through innovations with knowledge creation. The author points out that knowledge is created through the knowledge worker's mental activity involving the interaction of three important factors, i.e., information, knowledge and insight. Knowledge workers can augment their capability to exploit knowledge and information through their personal learning efforts and/or through access to appropriate external knowledge and information sources. Although importance of sharing information and knowledge has been widely discussed in earlier studies for knowledge management and social networking services, there were only few discussions on the importance of the third factor, insight. The author discusses that insight is the key for knowledge creation and it has a special nature different from the other two: it cannot be acquired through learning, but can become usable by activating undeveloped portions of native capabilities. Only knowledge workers who have good insight have the awareness to realize innovations necessary in business. These people are newly defined as Innovation Workers. In order to substitute for inefficient conventional on-the-job trainings to nurture innovation workers, a Timed-PDCA concept is proposed in this paper. The use of the Timed-PDCA concept makes it possible to visualize the progressive status of knowledge work as well as on-going thoughts of workers, and also periodically to enforce the worker for seriously evaluating the current situation and revising the action plan towards the final goal. Repeating such a process helps cultivate undeveloped portions of native capabilities of the worker. Visualization of work progress and worker's thoughts enable supervisors to coach workers in a timely and appropriate manner. Thus, use of the Timed-PDCA concept makes it possible to pursue productivity improvement in the current works including nurturing innovation workers concurrently. Although its application can be usefully made on any knowledge works to be managed on the time axis, managing the business-to-business sales process was chosen as the first concrete application. The paper introduces the development details of the system and its managerial effects after deployment. © 2011 Elsevier B.V. All rights reserved.

Interruption is occurred by partial participation of workflows with adding new activity to a worker. A concerned worker to the interrupted workflow must restructure task assignment to improve consumed operating time by interruption. An opportunity of decision making is occurred to the workers to select appropriate tasks. However, pre-assignment of tasks to workers includes an expectation of superior decision maker to a training of an inexperienced worker. In order to avoid overmuch improvement to the interrupted workflow, the alternatives for shortening operating time of tasks is computed by TOPSIS method. Although positive ideal solution and negative ideal solution in conventional TOPSIS method are based on objective attributes, subjective completion time of pre-assigned tasks that are positive ideal solution in this model is depending on subjective attributes of the worker. Therefore, this research proposes a novel extension of positive and negative ideal solution of TOPSIS method by aggregating based on subjective fuzzy attributes of the worker and objective attributes of tasks. The approach is examined on simple case study showing that the work is promising on providing solution to handle interruption on carried work in runtime.
