Many software enterprises prefer to use usual entrepreneurial approaches and make detailed business plans, which cost them a lot of time and resources. In the highly uncertain environment, the above practice lead to fail at business or entrepreneurship. To avoid the undesirable feature, software enterprises should adopt lean start-up method. The core idea of lean start-up method is to put in a minimalist prototype on the market, and fast iterative product on the basis of customer feedback (Ries, 2011). Because customers are introduced to the products or service iterative innovation process, the enterprise can meet the needs of the market better and grow up rapidly. Meanwhile, the enterprise can find a suitable business model to achieve efficient operation or reduce the risk of entrepreneurship (Maurya, 2013). Combining case study and theoretical deduction, this paper will show a process for software enterprise using lean start-up method. Firstly, based on literature reviews, the paper will sum up the basic logic of lean start-up and specifically expatiate the five-step model for software enterprises which is “idea generation-customer validation-prototype creation-customer feedback-product iteration”. Secondly, this paper will give a lean start-up process for software enterprises. In the process, the first step is drawing a business model canvas rather than a detailed business plan, it may include nine blocks which are key partners, key activities, key resources, value propositions, customer relationships, channels, customer segments, cost structure and revenue streams, each block has a series of hypotheses (Blank, 2013). The second step is adopting the customer development method to test these hypotheses and adjust irrational hypotheses to satisfy customers’ requirements, this step is referred to as validated learning, with the aim of setting up a continuous customer feedback channel and achieving long-term sustainable development. The third step is adopting agile development to build minimum viable product and iterative the product according to customer feedback quickly, in order to reduce waste and save resources. It is essential for lean start-up to use a smaller, faster iterative process to verify the idea (Ries, 2011). Thirdly, this paper will use several typical cases of software enterprises to verify this lean start-up process. Finally, put forward the general rule of lean management so that it can provide reference for the software enterprises.

This study is about the development of information system software process quality evaluation model for domestic medium enterprises based on CMMI being used widely in the world. In this study, a new evaluation model is developed through establishing tailoring guide and its application to the existing mode by reflecting the quality management method and conditions of domestic medium enterprises within CMMI Level 2 and Level 3. The evaluation model is constituted 3 processes, 11 achievement goals, 50 practice activities and 125 evaluation items. The average point of quality evaluation of enterprises of insurance business shows 79.1 based on the evaluation model. The average point of the enterprises certified from CMMI is 82.7 which is 3.3 point higher than non-certified enterprises. This result means that the new evaluation model has similar results with the existing evaluation model while it also has discriminational characteristics compared with the existing model.

This paper introduce information technology of software process assessment. It consists of eight parts such as concepts and introductory guide, a reference model for processes and process capability, performing an assessment, guide to performing assessments, an assessment model and indicator guidance, guide to competency of assessors, guide for use in process improvement, and guide for use in determining supplier process capability.

This paper presents various information technologies of software product evaluation such as process for evaluators, process for developers, and process for acquirers. This study also introduces system life cycle processes and its application guide.

This paper analyzes the competitive power of domestic software industries focusing on the subjective rating of software development process. A survey is conducted to perform subjective evaluation of software development process of his/her company. Comparison between SPICE-experienced companies and non-experienced companies, between domestic companies and companies in developed countries are performed.

Purpose – The study aims to show the successful application of Six Sigma in software companies for process improvement. Research design, data and methodology – A mixed methodology has been used which include both qualitative and quantitative research. In the qualitative research methodology part, a detailed and comprehensive literature study have been carried out. The literature study consists of articles, books, web materials, discussion forms and others. In the quantitative research methodology part, interviews have been conducted. Results – Six sigma is the practical application of a theoretical statistical measurement that equates to 3.4 defects per million opportunities -a position of practically zero defects for any process or service. Initially originating in Motorola Inc. in 1985 as a response to drastic quality improvement pressures from the threat of Japanese competition, it quickly gained many followers particularly G.E., Allied Signal, Ford Motor Company etc. and more recently attentions have shifted to service environments. There are still some problems and misconceptions existed about the applicability of Six Sigma in software companies. Conclusions – The paper concludes that Six Sigma can bring large benefits for software companies too. Furthermore, software companies have already started to implement Six Sigma approach, like Ericsson, Tata Consultancy Service, etc.

The diagnostic software for the wastewater treatment plant using activated-sluge process is developed in order to increase the efficiency of management of the wastewater treatment plant. This software is based on the expert system and the visualized user interface including the diagnosis of quantitative and qualitative data. For the generalization of this software, the initialization of each unit process and updating the files can be possible.
