How do lean management organizations behave regarding training and development?

This paper analyses the role of training and development in lean management organizations. The hypothesis is that organizations characterized by lean management have a distinctive profile in terms of training and development. Specifically, it is hypothesized that lean organizations have the following features to a higher extent than non-lean organizations:

? employee involvement in training and development

? use of work groups for quality, product development and task flexibility

? attribution of importance to training in quality, customer orientation and people management

? line management responsibility for training and development of the employees

? use of job enlargement

? information of employees about management decisions

? use of team briefings and quality circles.

The analysis shows that it is possible to identify a relationship between lean management and training and development, although the statistical results could have been more significant. It is also discussed in the paper to what extent country-specific variables dominate (or are dominated by) company-specific characteristics. The general finding is that company-specific impact seems to be stronger than country-specific variables.

In general, it can be said that the lean management pattern as a company-specific variable is characteristic for most countries analysed (although to a varying degree). It is, however, sometimes confounded by country-specific variables. For instance, Turkey does not follow the general pattern, and the hypothesis can be supported only in selected minor areas. Hence, in this case country-specific variables outweigh company-specific variables. In most other countries, this is not the case.     

Pillar or platform—a taxonomy for process improvement activities in public services

Research into Lean in public services and particularly implementation, needs to develop from reporting cases to provide a taxonomy for researchers and practitioners. The paper outlines two approaches to process improvement activities (PIAs)—’Pillar’ and ‘Platform’ and tests the validity of these approaches through two organizational case studies (96 PIAs are considered). The degree to which this taxonomy supports decision-making is explored and issues associated with implementation are discussed.

Lean planning in the semi-process industry, a case study

The lean approach is an idealizing improvement approach that has an enormous impact in the field of operations management. It started in the automotive industry and has since been widely applied in discrete manufacturing. However, extensions to the (semi-) process industry have been much slower. Resource characteristics of the (semi-) process industry obstruct a straightforward application. The notion of the point of discretization for the (semi-) process industry is helpful here. This notion builds on the fact that in most (semi-) process industries there is a point in production where process production turns into discrete production. Downstream of this point lean principles are applicable in a straightforward manner, while upstream lean needs to be interpreted in a more liberal way. In this article we address this issue by a case study. The study considers how the principles of ‘flow’ and ‘pull’ production - suggesting a regular, demand-driven product flow - may be implemented for the (semi-) process industry by introducing cyclic schedules. The conjectures guiding the case study are: (i) Cyclic schedules fit in a lean improvement approach for the semi-process industry, (ii) Cyclic schedules help to improve production quality and supply-chain coordination and (iii) Discrete event simulation is a useful tool in facilitating a participative design of a cyclic schedule. The case study is extensively described to be able to judge how the context of the changes and the intervention process contribute to the results of the intervention.     

结合Landsat 8和GF 1数据的冬小麦种植空间分布提取

[目的]为探讨多源中等分辨率数据在冬小麦种植时空分布上的应用。[方法]利用2017年冬小麦关键生育期的Landsat8 OLI(抽穗期)和时间序列的GF-1 WFV(2016—2017生育期)数据,在分析各个行政分区的地表覆盖状况、作物结构和地块破碎度差别的基础上,将行政区划分为3种类型不同的提取单元并建立了适合于各自分区的提取模型:(1)利用关键生育期的OLI数据,采用监督分类—神经网络方法提取结构单一、地块齐整的怀远县种植区;(2)基于WFV数据构建五河县及城区种植区的冬小麦全生育期NDVI时间序列曲线,根据NDVI的时间特征构建冬小麦提取的决策树分类模型提取结构较复杂、混合像元明显的五河县及城区种植区;(3)在对关键生育期OLI-NDVI数据合理分割的基础上,采用最大似然的面向对象分类法获取种植密集、地块破碎的固镇县种植区。[结果]提取结果采用混淆矩阵和当年度统计数据相结合的方法进行精度评价,结果表明:(1)怀远县提取出的冬小麦提取总体精度为97.91%,五河县及城区提取出的精度为97.62%,固镇县的精度为97.42%;(2)全区域冬小麦提取的总体精度为86.82%,Kappa系数为0.84。与当年度统计数据对比的结果表明:2017年蚌埠市的准确提取面积精度可达97.91%,提取面积数据小于蚌埠市统计年鉴提供的统计数据,与调查的实际种植地块基本一致。[结论]采用不同方法提取不同空间分布特征的冬小麦种植面积具有较好的精度,该方法可以为市域冬小麦面积提取提供技术参考。     

What the hack? A growth hacking taxonomy and practical applications for firms

As companies become increasingly digital, growth hacking emerged as a new way of scaling businesses. While the term is fashionable in business, many executives remain confused about the concept. Even if firms have an idea of what growth hacking is, they may still be puzzled as to how to do it, creating a strategy-execution gap. Our article assists firms by bridging the growth hacking strategy-execution gap. First, we provide a growth hacking framework and deconstruct its building blocks: marketing, data analysis, coding, and the lean startup philosophy. We then present a taxonomy of 34 growth hacking patterns along the customer lifecycle of acquisition, activation, revenue, retention, and referral; categorize them on the two dimensions of resource intensity and time lag; and provide an example of how to apply the taxonomy in the case of a fitness application. Finally, we discuss seven opportunities and challenges of growth hacking that firms should keep in mind.
