Tuotannon budjettimallin uudistaminen elektroniikka-alan yrityksessä

Diplomityön tavoitteena on suunnitella ja toteuttaa tuotannon budjettimalli elektroniikka-alalla toimivalle yritykselle. Työn onnistumisen kannalta keskeistä on löytää vanhan budjettimallin puutteet sekä uudet tietotarpeet, joita tuotannon johto tarvitsee pyrittäessä kustannustehokkaaseen ja kannattavaan tuotantotoimintaan. Näiden tietojen pohjalta suunnitellaan ja toteutetaan uusi budjettimalli sekä kuvataan sen toimintaperiaatteet. Työn teoreettisessa osuudessa esitellään budjetoinnin tavoitteet, hyödyt, kritiikin kohteet sekä tyypillisen teollisuusyrityksen osabudjetit. Myös perinteiseen budjetointiin läheisesti liittyvät muodot ja sovellukset, kuten toimintopohjainen budjetointi, vastuualuelaskenta ja nollapohjabudjetointi esitellään. Budjettiseurannan ja eroanalyysin tärkeä merkitys tuodaan esiin. Ennen uuden mallin esittämistä tutkitaan vanhan budjettimallin toimintaperiaatteet ja heikkoudet. Empiirisessä osassa keskitytään tuotannon budjetin toimintaperiaatteisiin sen sisältämien osabudjettien kautta. Työn loppupuolella esitellään uuden budjettimallin antamat tulokset ja poikkeamat sekä arvioidaan budjettimallin toimivuutta. Budjettimallin tuottaman informaation pohjalta tuotannonjohtoa ja suunnittelua ryhdyttiin välittömästi tehostamaan välillisten kustannusten alentamiseksi. Tehostustoimet ilmenivät konkreettisesti positiivisena erona poikkeama-analyysissä suhteessa budjettiin. Rakennetun budjettimallin mallinnustarkkuus osoittautui hyväksi ja uudet esiin tuodut kustannuserät hyödylliseksi informaatioksi.

Use of Statistical Methods in Demand Planning

In a very volatile industry of high technology it is of utmost importance to accurately forecast customers’ demand. However, statistical forecasting of sales, especially in heavily competitive electronics product business, has always been a challenging task due to very high variation in demand and very short product life cycles of products. The purpose of this thesis is to validate if statistical methods can be applied to forecasting sales of short life cycle electronics products and provide a feasible framework for implementing statistical forecasting in the environment of the case company. Two different approaches have been developed for forecasting on short and medium term and long term horizons. Both models are based on decomposition models, but differ in interpretation of the model residuals. For long term horizons residuals are assumed to represent white noise, whereas for short and medium term forecasting horizon residuals are modeled using statistical forecasting methods. Implementation of both approaches is performed in Matlab. Modeling results have shown that different markets exhibit different demand patterns and therefore different analytical approaches are appropriate for modeling demand in these markets. Moreover, the outcomes of modeling imply that statistical forecasting can not be handled separately from judgmental forecasting, but should be perceived only as a basis for judgmental forecasting activities. Based on modeling results recommendations for further deployment of statistical methods in sales forecasting of the case company are developed.

Offering planning process development: Bridging the Offering Gaps and Consolidating Top Priority Needs in Product Offering

The aim of this Thesis is to study how to manage the front-end of the offering planning process. This includes actual process development and methods to gather and analyze information to achieve the best outcome in customer oriented product offering. Study is carried out in two parts: theoretical part and company related part. Theoretical framework is created introducing different types of approaches to manage product planning processes. Products are seen as platforms and they are broken down to subsystems to show different parts of the development. With the help of the matrix-based approaches product platform related information is gathered and analyzed. In this kind of analysis business/market drivers and cus-tomer/competitor information are connected with product subsystems. This gives possibilities to study product gaps/needs and possible future ideas/scenarios in different customer segments. Company related part consists of offering planning process development in real company environment. Process formation includes documents and tools that guide planning from the information gathering to the prioritization and decision making.

Determining risk potential through accidents and near-accidents: an empirical study in a steel factory

Fatal and permanently disabling accidents form only one per I cent of all occupational accidents but in many branches of industry they account for more than half the accident costs. Furthermore the human suffering of the victim and his family is greater in severe accidents than in slight ones. For both human and economic reasons the severe accident risks should be identified befor injuries occur. It is for this purpose that different safety analysis methods have been developed . This study shows two new possible approaches to the problem.. The first is the hypothesis that it is possible to estimate the potential severity of accidents independent of the actual severity. The second is the hypothesis that when workers are also asked to report near accidents, they are particularly prone to report potentially severe near accidents on the basis of their own subjective risk assessment. A field study was carried out in a steel factory. The results supported both the hypotheses. The reliability and the validity of post incident estimates of an accident's potential severity were reasonable. About 10 % of accidents were estimated to be potentially critical; they could have led to death or very severe permanent disability. Reported near accidents were significantly more severe, about 60 $ of them were estimated to be critical. Furthermore the validity of workers subjective risk assessment, manifested in the near accident reports, proved to be reasonable. The studied new methods require further development and testing. They could be used both in routine usage in work places and in research for identifying and setting the priorities of accident risks.

Sales and Operations Planning Implementation

The master’s thesis focused on implementing a sales and operations planning process. The main objectives were to create planning methods and tools for the implementation. The ultimate goal of the process, beyond this master’s thesis, is to balance the supply of products with customer demand, with optimized profitability. The theoretical part focused on giving a thorough view on the sales and operations planning process. The basis for a monthly planning cycle was identified. Methods, tools, and metrics for demand forecasting and operations planning were also introduced. Based on the theoretical part, a method for forecasting, a forecast spreadsheet, and a forecast accuracy metric were designed. A spreadsheet tool and methods were also designed for the monthly planning of production volumes, capacity, and inventory. The implementation progress was reviewed for two product families for three months. The sales and operations planning process was able to successfully identify a demand peak for the product families. Suggestions for the future of sales and operations planning were also made.

Production Cycle Optimization: Defining the Market Potential for a New Planning Tool

An optimization tool has been developed to help companies to optimize their production cycles and thus improve their overall supply chain management processes. The application combines the functionality that traditional APS (Advanced Planning System) and ARP (Automatic Replenishment Program) systems provide into one optimization run. A qualitative study was organized to investigate opportunities to expand the product’s market base. Twelve personal interviews were conducted and the results were collected in industry specific production planning analyses. Five process industries were analyzed to identify the product’s suitability to each industry sector and the most important product development areas. Based on the research the paper and the plastic film industries remain the most potential industry sectors at this point. To be successful in other industry sectors some product enhancements would be required, including capabilities to optimize multiple sequential and parallel production cycles, handle sequencing of complex finishing operations and to include master planning capabilities to support overall supply chain optimization. In product sales and marketing processes the key to success is to find and reach the people who are involved directly with the problems that the optimization tool can help to solve.

Venäjän tehtaan toimintamallin kehittäminen puusepänteollisuuden yrityksessä

Rakennusteollisuus on ollut kasvava teollisuudenala Venäjällä, joka on kasvattanut kysyntää myös ikkunateollisuudessa. Vuoden 2008 syksyllä alkanut maailmanlaajuinen talouskriisi vaikutti merkittävästi myös Venäjän talouteen, jonka seurauksena rakennusala oli Venäjällä vaikeuksissa. Asuntojen kysyntä Venäjällä on kuitenkin lähtenyt kasvuun uudelleen vuoden 2009 loppupuolella ja markkinatilanne on paranemaan päin. Suomalaiset rakennusalan yritykset toimivat pääasiassa Pietarin ja Moskovan alueella, jonka vuoksi Fenestra Oy on suunnitellut ikkunatehtaan perustamista Pietarin lähistölle. Työssä esitellään Venäjän ikkunamarkkinat sekä Fenestra Oy:n lähtökohdat ja suunnitelmat kokoonpanotehtaan perustamiseksi. Ikkunoiden puiset komponentit on tarkoitus valmistaa Suomessa, josta ne kuljetetaan kasattaviksi Venäjällä sijaitsevaan kokoonpanotehtaaseen. Työn tarkoituksena on kuvata Venäjän tehtaan toimintamalli prosessikuvauksien avulla, selvittää tullauskäytäntö Venäjälle vietäessä sekä määrittää toimintamalliin sisältyvät riskit. Teolliseen toimintaan ja varsinkin Venäjälle suuntautuvaan toimintaan liittyy riskejä, joiden toteutumiseen on mahdollista varautua riskienhallinnan avulla. Riskien tunnistamiseksi on käytetty vaarojentunnistusmenetelmää, HAZOP –poikkeamatarkastelumenetelmää. Menetelmässä nimettiin mahdolliset poikkeamat, niiden syyt ja seuraukset. Poikkeamat luokiteltiin eri luokkiin niiden vakavuuden ja todennäköisyyden perusteella. Lisäksi tarkastelussa annettiin ehdotuksia varautumiseen ja toimenpiteiksi poikkeaman estämiseksi tai riskien pienentämiseksi.

During recent years, mobile phone markets have changed significantly. Asian markets have become vital for the manufacturers with their millions of end users and multiple major mobile network operators. This has resulted in software development as global companies have research and development sites running in multiple locations, including Asia. The reasons behind this are not only in reducing labor costs but also in capitalizing on the local knowledge and knowhow. A ramp-up site has multiple effects in the software development and software release activities. This thesis focuses on representing the importance of software testing as part of software development process and highlighting issues that need to be considered during ramp-up activities. In addition this work tries to emphasize the importance of communication between parties and information gathering prior to setting up the ramp-up site. The output of this thesis was successful software testing site ramp-up within the set time limits. The quality of software testing work was assured and the ramp-up -project requirements were achieved.

Virtaviivainen hankintatoimi osana tuotantoprosessia

Tutkimuksessa on pyritty löytämään tuotantoprosessin läpimenoa haittaavia ohjaus- ja toimintatapoja sekä tiedonkulusta aiheutuvia ongelmia. Tutkimuksen tavoitteena on saada toimittajien, hankintatoimen ja tuotannon logistinen arvoverkko toimimaan virtaviivaisesti. Työssä on käytetty teoriaosassa kirjallisuustutkimusta ja empiirisessä osassa toimintatutkimusta. Nykytilan selvityksessä tutkittiin prosessin tieto- ja materiaalivirrat sekä mitkä ovat tärkeimmät toiminnot toimitusketjussa. Tutkimuksen ja prosessianalyysin pohjalta määriteltiin kehitysehdotukset prosessin toimintojen tehostamiseksi. Nykytilan kartoituksessa ilmeni suurimmiksi ongelmiksi logistiikka prosessissa voimakkaan kysynnän kasvusta aiheutuvat komponenttien ja raaka-aineiden saatavuusongelmat sekä pudonneen kysynnän seurauksena varastoihin sitoutunut ylimääräinen vaihto-omaisuus. Tutkimuksen tuloksena syntyi kehitysehdotuksia, joiden pohjalta uudistettavaan toiminnanohjausjärjestelmään voitaneen toteuttaa johtopäätöksissä ilmenevät asiat, joista merkityksellisin on myynnin ennustamisvastuun siirtäminen myynnistä tulosvastuussa oleville henkilöille.

Developing a Comprehensive Model for Marketing Planning — Combining the Major Approaches

Mix marketing and relationships marketing are two major approaches that often form a basis for organizational marketing planning. The superiority of these approaches has been debated for long without any rational conclusion. Lately there have been studies indicating that both of the major approaches are many times used side by side in marketing planning. There have been also studies suggesting that even combining the mix marketing and relationship marketing approaches might be possible. The aim of this thesis is to provide knowledge about the usage of mix marketing and relationship marketing approaches in organizations and possibilities in combining the approaches. Also a settlement of strengths, weaknesses and risks of combining is intended to provide. The objectives were met through the literature and a case study research. In the case study, interviews were conducted in order to gain a deeper knowledge about marketing planning in various organizations. Based on this study, the combining of the major marketing approaches will be possible and even recommended when keeping in mind few aspects which might cause some troubles in the combining process.
