A framework for managing future supply chain trends: utilization of lean, agile and leagile strategies
Waleed Rashad, 2020, doktorska disertacija

Opis: The supply chain has become very essential to run any business nowadays. Throughout the history of business, the professionals have been trying always to find out the best practice, and as long as the business concept is evolved over time, the practice, methodologies and techniques of doing the business also have been evolved. This evolvement led to the concept of supply chain initially and then later it became essential to have strategy for supply chain. The evolvement of the markets, globalization, and new technologies became very decisive subjects for building any supply chain and developing its strategy, but there are many other events that may take place which could enforce the supply chain decision makers to change the current approach of running their business. The dynamic business environment and the possible future trends of the global markets represent a real challenge for development of appropriate supply chain strategies, like lean, agility, and leagility. Therefore, it is very important to assess how different possible strategies are suitable for the future changes of the markets? This is to enable the supply chain to be prepared with adequate strategies for different future scenarios. To achieve this aim of preparing the supply chains for the future with adequate strategies, a deep study is done to research lean, agility and leagility, explaining the similarities and differences of these concepts. These strategies are dealing with the most important factors in supply chains; the time and the cost, what is the key reason for selecting these particular strategies lies in the fact, that they are concerned with improving the effectiveness and responsiveness in the supply chain and this is extremely important for the future. We continued study of these strategies by development of three possible future scenarios for energy scarcity, new international monetary system, and wars. The reason of developing these particular scenarios is because they are concerned with the most important political and economic events which could happen and affect the supply chains in the future (EY, 2013; Cook, 2006; Sokov, 2015). These scenarios are established to anticipate the possible challenges which could face the supply chain strategies in the future and to evaluate the suitability of supply chain strategies for such future scenarios. A survey of 150 supply chain professionals, who are working currently in the field of supply chain management, is done in two phases. The first phase is focusing on recognition of the opinions of surveyed supply chain professionals towards the supply chain strategies and their utilization. Based on the theoretical knowledge of the academic literature reviewed in this research, proposed scenarios, and the feedback of professionals in the survey, it was evident that supply chains’ managers need adequate framework, which will support improvement of current and future supply chain management. Therefore, the grounded theory methodology is used to create a new conceptual framework. The core idea of the proposed framework is to improve the global sourcing practice, which consequently will enable improving the management of supply chains according to the predicted scenarios. A second phase of survey is conducted to present the proposed framework to the supply chain professionals for evaluation. The proposed framework adds value to the global sourcing process, which enhancing the supply chain collaboration and helps to support the selected supply chain strategies for consideration – i.e., lean, agility, and leagility, to work better in the future. The proposed framework represents scientific contribution to the supply chain strategies utilization in practice. The results of this contribution are obviously to fill the gap highlighted by the supply chain professionals in the survey, who highlighted the essential need for improvement to the supply chain collaboration globally, and this will be the basic c

Global sourcing strategies
Waleed Rashad, Zlatko Nedelko, 2020, izvirni znanstveni članek

Opis: The main purpose of this paper is to develop a framework for utilization of lean, agile, and leagile strategies in the supply chains, where the core idea of the framework is to improve the global sourcing practices. Based on in-depth interviews with supply chain professionals and grounded theory approach, we constructed a framework of global sourcing improvement to support better utilization of lean, agile, and leagile strategies, which we believe can help the supply chains worldwide to act better, especially in various difficult conditions and sustain their business accordingly. Our proposed framework also contributes to the UN´s Sustainable Development Goals, since the core concept of the framework is to establish a new organization under the umbrella of the UN to improve the global sourcing and consequently the usage of supply chain strategies accordingly. The applicative part of the paper reveals characteristics of new developed framework, ranging from its purpose and aims, structure, key processes, functions, and its financing. Along with validation of the framework are presented benefits for society, industry, and global economy. Additionally, the paper also reviews the impact of the current health and economic crisis caused by COVID 19, on usage of the three supply chain strategies namely; lean, agility, and leagility to see how they can work in the difficult time, as COVID 19.

Lean manufacturing effects in a Serbian confectionery company
Ilija Djekic, Dragan Zivanovic, Sladjana Dragojlovic, Radoslava Dragovic, 2014, izvirni znanstveni članek

Opis: Background and Purpose: The objective of this paper was to evaluate effects of implementing lean manufacturing in a Serbian confectionery production company during a period of 24 months, emphasizing observed benefits and constrains. Company ‘case study’ is a leading confectionery producer in Serbia with annual production of more than 25,000 t. Methodology/Approach: The research method was case study. The approach in implementing lean manufacturing was structured in five phases, as follows: (i) training, (ii) analysis of lean wastes on one technological line, (iii) choice of lean tools to be implemented in the factory, (iv) implementation of lean tools in production and maintenance, (v) development of continual improvement sector and further deployment of lean tools. Results: Lean manufacturing tools implemented in the production process were visual control and single minute exchange of dies (SMED). Maintenance process implemented 5S with total productive maintenance (TPM) and problem solving sessions being the tools implemented in both processes. During the observed period, results of these tools showed the following: visual control tables initiated 61 improvement memos out of which 39% were fully implemented; a total of 2284 minor problems had been recorded, with over 95% of issues revealed in due time; total SMED time decreased for 7.6%; 19 problem solving sessions were initiated with 58% of solving effectiveness, and the remaining converted to on-going projects. In maintenance 5S improved from 29.9 to 60.3; overall equipment effectiveness (OEE) indicator increased from 87.9% to 92.3%; mean time between failure (MTBF) increased for 16.4%. Conclusion: As a result of all activities, 20 in-house trainings and 2 ‘kaizen’ events including motivational training have been initiated with 54 documents being revised and improved in order to contribute to more efficient processes.

Exploring approaches how to measure a lean process
Christer Österman, Anders Fundin, 2014, izvirni znanstveni članek

Opis: Purpose:The purpose of the research is to explore a practical method of measuring the implementation of lean in a process. The method will be based on examining the abilities of a group. At this scale the ability to work standardized and solve problems is important. These two abilities are dependent of each other and are fundamental for the group's ability to create a stable result. In this context the method of standardized work (SW) is define to be the methods used in a process to generate stable results. Problem solving (PS) is defined as the methods used to return a process to a condition where SW is possible. Methodology /approach: The research is conducted in a multiple case study in four large global manufacturing companies. The order of the data collection is: Firstly, interviews with the individuals that are centrally responsible for overall implementation of lean in the organization. Secondly, observe the implementation of SW and PS at the group level. In total 7 groups have been studied and 19 respondents interviewed. Findings: Results show that the central definition of the methods for standardized work does not by itself have a direct impact on success of implementation of SW at group level. The method of SW where similar on a general level in the different cases, but with varying levels of implementation at group level was applied. Results also show that key factors for a successful implementation of standardized work on group level are: Ownership of the process, Direct connection to result of process, Correct workload and Leader demand. Methods of PS at group level where dissimilar despite a superficially similar approach. The evaluation method used was successful in providing comparable results between the cases. Research limitations: A limitation of this research is within the scale of the measurement, as it only examines the group level. The research is further limited to four companies and seven groups. Originality/value of paper: This paper aims to fill a gap in the established measurement methods of lean, as it examines the abilities of SW and PS at the group level of a process. These abilities are often referred to as essential in lean theory. However, there has been little scholarly work in defining the methods of SW and PS or the key factors affecting the methods at an operational level.

Uporaba lean startup metodologije v praksi
Urška Rozinger, 2017, diplomsko delo

Opis: Diplomska naloga je sestavljena iz dveh delov. Prvi del prestavlja teoretični del, ki zajema podatke o tem, kaj je lean start up metodologija v praksi, s katerimi ovirami se srečujejo podjetniki pri uporabi te metode in kako lahko premagujejo ovire in možnost propada podjetja. Problem, ki se pojavlja, je ta, da podjetniki prehitro sklepajo zaključke, kar že v začetni fazi vodi v neuspeh. Veliko podjetij tako močno verjame v svojo idejo, da ne vidi odjemalcev in njihovih dejanskih potreb in problema, katerega želi rešiti. Podjetnik ima v mislih idejo, ki predstavlja neko rešitev za odjemalce. Sam je prepričan, da jo bodo odjemalci kupili in jim bo predstavljala rešitev, s katero bodo problem odpravili. V kolikor podjetnik ne naredi analize odjemalcev, se informira o trgu in razišče svoje konkurente, je obsojen na propad. Ključnega pomena je, da naredi celotno analizo, da gre ven iz stavbe, naredi analizo odjemalcev, posluša in jih sprašuje o problemu, katerega želijo odpraviti in so za njega pripravljeni plačati z denarjem. V kolikor si je podjetnik pripravljen vzeti čas in se poglobiti v odjemalce, se bo izognil temu, da bo vložil v podjetje znesek denarja, za idejo, katera nima prihodnosti. Več potrebnih informacij bo zbral, večja bo možnost, da bo s svojo rešitvijo uspel in imel uspešno ter dobičkonosno podjetje. Drugi del predstavlja praktični del, ki zajema anketne vprašalnike in anketiranje podjetij. Predvsem sem želela izvedeti, ali se podjetja poslužujejo te metode, katere ovire so tiste, s katerimi se soočajo, in ali je to metoda, ki vodi v uspeh in jo bodo uporabili še v prihodnje. Anketiranih je bilo 5 naključnih podjetij iz različnih panog, torej podjetja, katera se ukvarjajo z različnimi dejavnostmi. Te sem izbrala, saj sem želela raziskati, kako različna podjetja dojemajo nove posle in njihovo trženje na trgu.

Lean and green paradigms in logistics
Vaska Pejić, Tone Lerher, Borut Jereb, Andrej Lisec, 2016, pregledni znanstveni članek

Opis: This paper provides a systematic review of published research on lean logistics, green logistics and the combination of both paradigms. Although prior research on all three topics exists, only a few have focused on the field of logistics as such. The present analysis comprises an examination of 98 scientific articles from 35 international journals, published between the years 1994 and 2015. The published studies are classified by next divisions: journal, paradigm, time distribution, research stream and sector-wise focus. Although key findings indicate that over the last couple of years research on all three topics has increased, a research gap regarding the studies of lean and green logistics when combined, has been identified. For all three topics the domination in research typology has been extracted. The findings indicate that most papers examined on the topic of lean logistics come from the manufacturing industries, whereas for the topic green logistics and a combination of green and lean topics no specific sector was identified.

UPORABA METODOLOGIJE LEAN SIX SIGMA V ZDRAVSTVENI NEGI
Mirjana Mandić, 2016, diplomsko delo

Opis: Teoretična izhodišča: Metodologiji Lean in Six Sigma sta bili prvotno neodvisni ena od druge. Lean je metodologija za izboljšanje in optimizacijo proizvodnih procesov in storitev. Osredotočena je na izboljševanje kakovosti z zmanjševanjem napak in odpada v procesih. Prvotno jo je razvila avtomobilska industrija Ford leta 1913, dopolnilo in nadgradilo pa podjetje Toyota. Six Sigma je metodologija za izboljšanje procesov s pomočjo podatkov, s katerimi se dosežejo stabilni in predvidljivi rezultati z zmanjšanjem odstopanj in napak v procesu. Razvilo jo je podjetje Motorola. Obe metodologiji sta se združili kot Lean Six Sigma (LSS) in sta s svojimi orodji in načinom interpretacij za izboljšanje delovnega procesa odlična kombinacija za izboljšanje delovnega procesa. Sčasoma so jo pričeli uporabljati tudi na drugih področjih oz. organizacijah kot so šole, bolnišnice, uradi, farmacija idr.. Namen diplomskega dela je predstaviti uporabo metodologije Lean Six Sigma v zdravstveni negi. Raziskovalna metodologija: Diplomsko delo je nastalo s pomočjo deskriptivne metode dela. Z analizo in študijem strokovne in znanstvene literature smo predstavili uporabo metodologije LSS. Pri tem smo uporabili bibliografsko bazo COBISS/OPAC in tuje bibliografske baze CINAHL, Medline, PubMed, ScienceDirect in Google Scholar. Razprava: Zdravstvene ustanove, ki nudijo zdravstvene storitve, se v delovnem procesu srečujejo s problemi in napakami, ki zmanjšujejo učinkovitost dela, ogrožajo pacientovo varnost, zmanjšujejo kakovost, povečujejo stroške in čakalne dobe, kar se kaže pri pacientih in zaposlenih z nezadovoljstvom. Ovire nastanejo običajno pri optimizaciji delovnega procesa zaradi pomanjkanja časa, neznanja, slabega pretoka informacij, pomanjkanja števila oseb idr.. Na podlagi študije primerov prikazanih v diplomski nalogi, so vidna izboljšanja, ki so jih dosegli s pomočjo vpeljave metodologije LSS v proces zdravstvene nege. Sklep: V diplomskem delu smo predstavili in opisali najpogostejše metode in orodja ter prikazali primere dobre prakse pri uvajanju metodologije v bolnišnicah oz. zdravstvenih ustanovah. Prikazano je, da že z osnovnimi orodji in metodami lahko učinkovito in stroškovno izboljšamo delovne procese.
