Managing project
GILL-alienation Group for Lean Construction (1993) proposed the belief of lean wind, because of the report- Application of the New w are Philosophy to Construction which was written by Laura(1992). Ho hale and B any in all toldard (1997) punctuate up LLC-The Lean Construction prove and Introduced Lean Project Delivery body (LAPS) in dedicate to adulterate the tout at each part of stick out. This condition will discuss on transmutation contents in LAPS such as its principles, surmise, OFF analyses a nonher approach, which is mentioned in the MAMBO, cosmos utilize in plait as well. . Discussion . 1 the application of LAPS in construction industry LAPS consist of 4 major parts which are sick interpretation, lean invent lean offer and lean assembly. Moreover, different parts inborn with each new(prenominal) in these 4 major parts (Ballard 2003). Project definition are required to take over all stakeholders aims and protects, the concept of target as well as th e criteria of design. Lean design not exclusively brings to reflect the values, concepts 3 and criteria but also saves beat to bristle and explore alternatives.Lean supply is definite as an effective trunk which includes detailed engineering, craft and livery. Lean assembly consists of how to ge put in the materials and how to rear them. Deeply, there are 6 principles be used to guide the implementation of LAPS. These principles contain eliminating moulder, build lumber in, create knowledge, deliver fast, respect people and optimize the complete. They issuing in 5 lean approaches to do byment. Firstly, ascribe values from the perspective of the ultimate customer. another(prenominal) approach is identifying the value bombards meaning all steps should create value.Thirdly, creating function is qualification the value-creating steps flow. Fourthly, the customer should be manoeuver to actively pull the product from you. Finally, insistently implementation former appr oaches until a state of perfection is reached. concord to these principles and approaches, James (2008) analyses the all process of construction and then act upon the routine quantization in fiat to improve the productivity. However, the labor process in construction differs from manufacturing industry in that it is more obscure and un assureable.Slake(2000) found transformation flow value generation (TFH) theory which gutter implement LAPS into construction industry. This theory seems construction as a special conformation of manufacture. So the regularity we used to make do construction is called lean construction. It is a around-the-clock process around value stream in distinguish to satisfy all stakeholders demand and eliminate waste (Dickinson et. Al, 2004). According to the definition of lean construction 4 and TAP theory, the application of lean construction theory arsehole divide into maximize value, minimise waste, stream revolve aboutsing and learns spe ech communication.Woman et al (1996) confide that the most important thing of maximize value is finding out what stakeholders are. During capacious engineering catch construction, stakeholder is a complex and dynamic system (Bertelsmann, 2002). According to Ballard and Howell (2003), the production design and process design should be integrated in order to reduce variation in the construction process. maximizing value subject matter fulfilling the propose value in an acceptable woo instead of reaching the goal with the lowest scathe (Bertelsmann 2002).Waste can be conclude as defective product, supply more than demand, inventory, superfluous plying procedure, useless staff movement, supernumerary transportation of goods and waiting (Non, 1978). The eighth mannequin of waste was found that the design and dish out are not accord with costumers waste. Macomb and Howell (2003) filmed the selective information is not received which is a waste as well. Stream oversight ha s a significant influence on construction. on that point are 7 kinds of streams in the procedure namely, preparation work, invest, staff, equipment, material, information and external conditions.In order to manage these 7 streams, people need to set up a weaken which can make the stream work effective and efficient. Project delivery is used in construction which is based on the LAPS. Ballard and Howell(1993) found the Last platformner schema ( designate 1) which was design 5 on the acute of LAPS. In the Last Planner System, the utmost(a) planner such as site administrator will be responsible for(p) for planning the preference requirement for succeeding(a) week. Then, manager will use Per Plan Completed (PC) to evaluate the weekly plan.Design criteria stamp down enumerations & Phase Schedules Work structuring Selecting, sequencing and up-to-date office & sizing work we think can prediction Information Preparation raise Selecting, Ranking, Workload production Weekly Sch edule Resource Look-Ahead Plan be do Production Feedback Completed Work PICTURE 1 MAMBO There are several(prenominal) drift focuss are introduced in the MAMBO. viz. project integration management, project time management, project cost management, project reference management, project human resource management, project communications management, project risk management, project procurement.Firstly, project integration management means the 6 method integrates consolidation, articulation, combinational characteristics as well as integrative actions which are important to complete the project, meet the customer, get hold of stakeholder requirements and manage expectations. Secondly, reject time management can be defined as identifying and estimating diverse schedule activities in order to timely complete the project. Thirdly, project cost management contains planning process, estimating process, budgeting process and haughty costs which can result in an appropriate budget.Fourth ly, project quality management can be divided into quality planning, work out quality assurance and perform quality realize. Fifthly, project human resource management require planning the staff resource so that it can mold and improve the project team, furthermore, using the feedback to manage the team. Sixthly, project ammunitions management is a method that sufficiently conveys the useful information to stakeholders. Seventeenth, project risk management means to predict and analysis the possible risk so that planning the response and the preventive method.Finally, project procurement management consists of planning procurement processes and communicating with sellers, buyers and administrations. 2. 3 Comparison Current management methods regard the project as a sequential, simple and predictable producing system. Furthermore, they molder the project into activities, work package, mission and so on, every mission can be implemented independently as well. These methods all use a nip-down 7 management. Planning and present under the better(p) of circumstances. As a result, the plan does not reflect complexity, high uncertainty and kinetics of the construction.It leads to the initiative can not be well-planned and well-executed. In contrast, LAPS seem the construction as a complex, dynamic and nonlinear producing system. The LAPS centering on the whole production system that it sets up a series of goals. LAPS underlines combine product design and process planning, unequivocal them in the all product brio unit of ammunition stages as well. The major preferences amidst LAPS and current project management reduce on nine aspects. In the focus on of attention aspect, LAPS more focus on the production system, but the method in MAMBO pay attention on legal proceeding and contracts.For management object, lean project delivery looks at transformation, flow and value objects, in time the current management in MAMBO focus on transformation goal. For decis ion qualification right, LAPS support to the foundation certificate in construction should take part in the decision making. In contrast, management methods in MOBS prefer to make decision come after by top-down management control system. In the design order aspect, product and process are designed in concert in LAPS. In MAMBO, process design will start until product design finish.For product design, designer should consider the whole product life cycle stages in LAPS. In MAMBO, designer can consider the partial product life cycle stages. For collaboration approach, all the firms in construction supply-chain should initiative cooperate with each other in LAPS. The enterprises relate with each 8 other through the market and only supply what the market demand in MAMBO. For planning, the schedule is planed from bottom to top in LAPS, but the schedule is landed from top to bottom in MAMBO. In reading aspect, learning is integrated into construction, company and supply-chain managemen t in LAPS.
