    APPLICATION BACKGROUND AND BUSINESS /

    MARKET ANALYSIS LEADING TO PROJECT DEFINITION.

    Articulation of products /services and target customers. Clarity of business/market analysis, what are the

    success factors. What are the project deliverables, project quality statement?

    TELECOMMUNICATIONS MANAGED SERVICES PROVIDER

    Ericsson (2007) defined Managed Concept Services as A Managed Service is provided by a service

    provider that takes on management responsibility for a function that has traditionally been carried out

    internally by a telecom operator.

    Managed Services include establishing, operating and managing day-to-day operations of a telecom

    operators network, services and business support systems. TheProvider, provide for the telecom operator

    the required network capacity, hosting of content, applications and enablers when and where needed.

    They are telecom equipment vendors that leverage their expertise to supply additional services to

    customers, and other playersnon-traditional telecom vendors. Generally, Customer Relationship

    Management (CRM) services is provided in-house by the operator.

    REASONS WHY OPERATORS USE MANAGED SERVICES

    Telecom operators use the managed service providers for the following reasons;

    With increasing financial pressure due to increasing competition, operators can increase their profits by

    outsourcing functions to a partner that can provide higher efficiency and economies of scale than an

    individual operator can achieve.

    Due to an increasing degree of complexity, operators can reduce their need to build network and services-

    related competence and outsource this to Managed Services providers whose core competence in

    managing this complexity brings in higher quality and better network performance thereby meeting

    customers requirements.

    Outsourcing thesecomplex functions, allow the operator to focus more on its core business area which is

    revenue-generation. Through increase in market share and customer base.

    EATON TOWERS GHANA

    Eaton Tower is a telecommunications managed services provider that provides network infrastructure and

    related services to mobile operators in emerging markets. It operates Telecommunication sites and co-

    location slots .Eaton Towers has about 1,000 Tower sites available for co-location in Ghana and South

    Africa.

    "Tower sharing brings benefits to all parties, allowing operators to broaden coverage and quality of

    service whilst cutting capital investment and operating costs..

    Eaton Tower Management model can deliver savings in site operation costopen of up to 40% to the

    operator. Eaton Tower funds and build new site, thereby reducing and subsidizing cost of site build and

    operations cost to the operator.

    Vodafone Ghana Outsources Tower Management to Eaton Towers.

    On 5th Oct., 2010, Eaton Towers, the African tower company, signed a 10 year contract with Vodafone

    Ghana to take over the operations and co-location management of 750 telecom towers.

    Over the life of the contract Eaton is expected to invest up to $80 million on upgrading and improving the

    existing towers and on improving Vodafones network coverage in Ghana. Eaton will also upgrade and

    maintain the existing infrastructure and build new sites.

    The contract also empowers Eaton to sell co-location and shared-infrastructure facilities to other mobile

    operators, generating future revenues from separate long-term contracts.

    By outsourcing the management of its towers to Eaton Tower, Vodafone Ghana will benefit from cost

    savings and significantly reduced capital expenditure.

    Eaton is responsible for all operational aspects of the passive infrastructure, including health and safety,

    security and power provision. Upgrades to the existing sites will comprise new power generation

    equipment and advanced management systems aimed at reducing diesel consumption and other costs.

    The Class 1 Surge Protection and Earth Improvement Project

    What is a Project?

    According to Project Management Body of Knowledge PMBOK Guide (2008) A project is defined as atemporary endeavor undertaken to create a unique product, service or result.

    It has a beginning and an end.

    It has a purpose

    It consists of interrelated activities.

    The end is reached when the projects objectives have been achieved or when it is terminated because itsobjectives will not or cannot be met or when the need for the project no longer exists.

    Project Initiation

    Project Outline

    It has been observed that Vodafones passive infrastructure is not adequatelyprotected from commercial

    power spikes caused by lightning strikes, power surges etc. There is a high turnover rate of ATS and

    Generator Control Panels; largely due to power spikes received from the commercial mains lines.

    Existing Class I surge protection has been reportedly installed in the wrong location and some sites have

    direct lightning strikes and arrestors being physically bypassed. The Class 1 Surge Protection Project will

    identify sites without protection and correct the site protection. Prior to this project the site earth project

    would have been completed.

    The four main areas that this project will address are

    A. Move or Replacerelocate arrestor to correct position and if damaged or under duress, replace with

    new unit

    B.Earth ConnectionThis will include installation of 16mm2 earth conductor to earth ring

    C. New InstallationThis includes Lightening arrestors, earth down conductors, Transector high breed

    surge units installed in weather proof meter box enclosure,

    D.Earth Checksincludes Megger tests to determine correct earth readings

    Further complexities to this project will result due to the heterogeneous equipment installed over the past

    ten years and lack of information on existing surge arrestors and their condition, this will make it difficult

    to forward plan materials and timelines.

    QUALITY PLANS AND ROADMAP.

    Quality is defined as the totality of features and characteristics of a product or service that bear upon its

    ability to satisfy stated or implied needs.

    Project Quality Management Processes

    QUALITY PLANNING

    This involves identifying which standards are relevant to the project and determining how to satisfy them.

    It is the use of quality tools such as benchmarking, cost/benefit analysis, design of experiments, cost of

    quality etc. This is executed concurrently with all knowledge areas and processes.

    PERFORM QUALITY ASSURANCE

    This is the application or execution of planned systemic quality activities to ensure that the project will

    employ all processes needed to meet requirements. It is the structured review of quality activities or

    lessons learned.

    PERFORM QUALITY CONTROL.

    This involves monitoring specific project reports to determine whether they comply with relevant

    standards and identifying ways to eliminate sources of unsatisfactory results. It is executed during project

    controlling phase. The seven quality tools used are Marginal Analysis, Kaizen, JIT, ISO 9000, 14,000 etc.

    PLAN QUALITY; TOOLS AND TECHNIQUES

    CostBenefit Analysis

    This is the comparison of cost to benefit of quality. The benefits of quality include less rework, higher

    productivity, less defects and meeting customers expectation.

    Cost of Quality (COC)

    This is the costs incurred in preventing nonconformance to requirements, evaluation of product or service

    for conformance to requirements and failing to meet customers requirements (rework).

    Fig 3.

    Control Charts

    This is used to determine if a process is stable or if its performance is predictable. Upper and lowerspecifications are the boundaries acceptable to the customer in meeting his requirements. The customer

    rejects any thing is falls out from the limits. Upper and lower control limits are set by the project manager

    and stakeholders to represent the point corrective measures will be taken to prevent exceeding

    specification limits. A process is out of control when a data point exceeds a control limit or if seven

    consecutive points are above or below the mean. Control charts can be used to monitor repetitive

    activities, cost and schedule variance, volume and frequency of scope changes etc.

    Fig 3 Control chart.

    Benchmarking

    This involves comparing actual or planned project practice to other comparable projects to determine best

    practices, improvement and basis for measuring performances.

    Design of Experiments

    PMI (2008) defines Design of Experiments as a statistical method for identifying which factors may

    influence specific variables of a product or process under development or in production. It provides the

    statistical template for systematically changing all of the important factors, rather than changing the

    factors one at a time.

    SYSTEMATIC APPROACH TO QUALITY MANAGEMENT

    USING SIX SIGMA STRATEGIES

    (Sivaram 2009) defined Six Sigma is a well structured, data-driven methodology for eliminating defects,

    waste, or quality control problems of all kinds in manufacturing, service delivery, management, and other

    business activities. It is an institutionalized rigorous,disciplined ,fact based method to deliver more money

    to the bottom line through process improvement and process design projects ,selected by the top

    leadership and led by high potentials trained as Black Belts or Master Black Belts in Six sigma with the

    aim to create near perfect process ,products and services all focused to meeting customers

    requirements..(Kaizen 2010) definedSix sigma as. A system of continuous improvement in quality,

    technology, processes, company culture, productivity, safety and leadership.

    Six Sigma is used as tools for improving processes and products and as an approach for improving both

    the process- and people-related aspects of business performance. Six Sigma is also used as a hands-on

    approach to developing leadership and change management skills.. GE(2000) describes the changes

    brought by Six Sigma this way: Six Sigma has turned the Companys focus from inside to outside,changed the way we think and train our future leaders and moved us toward becoming a truly customer-

    focused organization.The main focus of Six sigma management is that if defects or non conformance can

    be measured in a process, systematically ways of elimination of defects can be initiated, to approach a

    quality level of zero defects or non conformance.

    SIX SIGMA QUALITY STRATEGIES

    To achieve Six Sigma quality, a process must produce no more than 3.4 defects per million opportunities.

    An opportunity is defined as a chance for nonconformance, or not meeting the required specifications.

    Key Concepts of Six Sigma

    Critical to Quality Attributes most important to the customer

    Defect Failing to deliver what the customer wants

    Process Capability What your process can deliver

    Variation What the customer sees and feels

    Stable Operations Ensuring consistent, predictable processes to improve what the customer sees and feels

    Design for SixSigma Designing to meet customers needs and process capability

    Six Sigma Methodologies

    The methodology of six sigma is based on the combination of well defined statistical quality control

    techniques, simple and advanced data analysis methods, and the systematic training of all personnel at

    every level in the organization involved in the activity or process targeted by Six Sigma.

    The methodology is to improve a business process by constantly reviewing, updating and re-tuning the

    existing process

    Six Sigma improves the process performance, decreases variation and maintains consistent quality of the

    process output. This leads to defect reduction and improvement in profits, employee morale, product

    quality and finally customer satisfaction.

    Six Sigma Strives for perfection. It allows for only 3.4 defects per million opportunities for each product

    or service transaction

    (Kaizen 2010) said that Six Sigma is a methodology to improve a business process by constantly

    reviewing, updating and re-tuning the existing process.

    Six Sigma improves the process performance, decreases variation and maintains consistent quality of the

    process output. This result in defect reduction and improvement in profits, employee morale, product

    quality and customer satisfaction.

    It allows for only 3.4 defects per million opportunities for each product or service transaction.

    Six Sigma uses statistical techniques to reduce defects and measure quality

    Six Sigma level and process.

    Three Levels of Six Sigma

    As a Metric

    1. Six Sigma is a scale of level of quality

    2. Equates to 3.4 defects per one million opportunities (DPMO).

    3. It is a defect reduction process that can be applied to any business processes.

    As a Methodology

    As a business methodology it focuses an organization on;

    1 Understanding and managing customer requirements

    2 Aligning main businesses processes to achieving these requirements.

    3 Applying rigorous data analysis to minimize variations in those processes.

    4 Maintaining rapid and sustainable improvement to businesses.

    As a Management Systems

    A top-down solution to assists organizations:

    Align their business strategy to critical improvement efforts

    Select and mobilizeteams to execute high impact projects

    Accelerate improved business results

    Manage processes that will ensure improvements are sustained

    Framework to prioritize resources for projects that will improve the metrics and it supports leaders whowill manage the efforts for rapid, sustainable, and improved business results.

    LEVELS OF SIX SIGMA IMPLEMENTATION

    Champion: Champions undergo five days of training and are taught how to manage projects and act asadvisors to various project teams.

    Green Belts: They are trained for two weeks of training that includes project-oriented tasks. They act asteam members to the Six Sigma project team.

    Black belts: They are trained for four weeks and are directly involved in the implementation of Six SigmaProjects. They are the project leaders and go through in-depth training on Six Sigma approach and toolsand work full time on the project.

    Master Black Belts: They conduct Six Sigma Training and also have on the job training and experience.

    SOME SIX SIGMA TOOLS

    QUALITY DEPLOYMENT FUNCTION

    Quality Deployment Function helps Six Sigma Black Belts drive customer-focused development acrossthe design process.

    Quality Deployment Function is a system and set of procedures to identify, communicate, and prioritizecustomer requirements.

    Quality Deployment Function helps Six Sigma teams focus more on activities that have the highest levelsof impact on meeting customers requirements, beat the competition and focus with the mission of theorganization.

    CAUSE AND EFFECT

    The Cause &Effect Matrix helps Six Sigma project leaders facilitate team decision-making.

    The Cause &Effect Matrix helps Six Sigma teams select, prioritize, and analyze the data they collect overthe course of a project to identify problems in that process.

    The Cause &Effect Matrix is used in the Measure phase of the DMAIC methodology.

    The Cause & Effect Matrix helps teams to reach consensus on the potential relationships between factorsthat affect a process and the output of that process

    FAILURE MODES EFFECTS ANALYSIS

    FMEA helps Six Sigma teams to identify and address weaknesses in a product or process, before theyoccur.

    Before new products, processes, or services are implemented, Six Sigma teams use FMEA to identifyways these newproducts, processes, or services might fail, and which will help team develop preventativemeasures targeted at the failure scenarios.

    FMEA identifies corrective actions required to prevent failures from reaching the customer and willimprove performance, quality, and reliability

    T-TEST

    The t-test helps Six Sigma teams validate test results using small sample sizes.

    The t-test is used to determine the statistical difference between two groups, not just a difference due torandom chance. Six Sigma teams might use it to determine if a plan for a comparative analysis of patientblood pressures, before and after they receive a drug, is likely to provide reliable results.

    22/38

    22

    CONTROL CHARTS

    Six Sigma teams use Control Charts to assess process stability.

    Control Charts are highly effective tool for monitoring and improving process performance over time. It

    is used by Six Sigma teams to observe and analyze variation.

    The three basic components of control chart are a centerline, upper and lower statistically determined

    control limits, and performance data plotted over time.

    DESIGN OF EXPERIMENTS

    DOE helps Six Sigma Black Belts make the best use of valuable resources.

    DOE is a statistical technique that comprise of planning, design, data collection, analysis and

    interpretation strategy.

    DOE is used to determine the relationship between factors (Xs) affecting a process and the output of that

    process (Y).

    Six Sigma Quality strategy sequence (DMAIC)

    DMAIC (Define, Measure, Analyze, Improve and Control)

    Define. The Definephase defines project goals and boundaries, and the identification of issues that need

    to be addressed to achieve the higher (better) sigma level.

    Measure. TheMeasurephase of the Six Sigma strategy is to gather information about the current

    situation, to obtain baseline data on current process performance, and to identify problem areas.

    Analyze. TheAnalyzephase is to identify the root cause(s) of quality problems, and to confirm those

    causes using the appropriate data analysis tools.

    Improve. TheImprovephase is to implement solutions that address the problems (root causes) identified

    during the previous (Analyze) phase.

    Control. The Controlphase is to evaluate and monitor the results of the previous phase (Improve).

    The DMAIC Six Sigma quality strategy sequence is an application used in process improvement project.

    DMAIC is a process for continued improvement. It is systematic, scientific and fact based. It is a closed

    loop process that eliminates unproductive steps, and focuses on new measurements, and applies

    technology for improvement.

    The DMAIC six sigma quality strategy will be applied in the Surge Protection and Earth Improvement

    Project.

    The word sigma, a statistical term measures how far a process deviates from

    perfection.

    Defect A measurable characteristic of the process or its output that

    is not within the acceptable customer limits, i.e., not conforming to

    Specifications. The sigma level of a process is calculated in terms ofdefects per million opportunities (DPMO).

    Figure 6.6. DPMO at sigma levels

    Six Sigma relies heavily on statistical techniques to reduce defects and measurequality.

    It measures a process in terms of number of defects. The statistical concept of sixsigma means that the processes are working nearly perfectly ,delivering only 3.4defects per million opportunities(DPMO).

    Six steps to six sigma

    1. Identify the product you create or the service you provide2. Identify the customers for your product or service and determine what you

    consider important.3. Identify your needs to provide product /service so that it satisfies the customer4. Define the process for doing the work5. Mistake the proof the process and eliminate wasted effort6. Ensure continuous improvement by measuring, analyzing, and controlling the

    improved process.

    Design for six sigma (DFSS)

    This is a systematic methodology using tools, training and measurements to enable

    the design of products, services and processes that meet customer expectations at six

    sigma quality levels. DFSS optimizes the design process to achieve six sigma

    performances and integrates characteristics of six sigma at the outset of new product

    development with disciplined set of tools.

    Conclusion

    The aim of Six Sigma is to achieve the target of 3.4 defects per a million

    opportunities, but from the above calculation of 1.5 sigma level which is 50% defect

    free, there is need for continuous improvement of the process

    Recommendations

    The critical success factors for Six Sigma effectiveness recommended for continuous

    improvement are;

    1. Strong proactive support with required resources provided by top management..

    2. High value should be placed on understanding and satisfying customer needs.

    3. The right project should be combined with the right people and right tools.4. There should be acceptance and implementation of Six Sigmas basic discipline

    5. There should be linkage with all innovative and infrastructural activities

    6. There should be accurate and fair evaluation of all successful six sigma

    7. Projects with intrinsic and extrinsic recognition and rewards for staff.

    8. The Company should invest on adequate resources.

    9. There should be focus on results.

    10.The company should embark on customer orientation

    11.Company should focus on training of staff for specific roles as Six sigma champions,

    Green Belt Black Belt and Master Belt holders for adequate implementation for Six

    Sigma quality strategy.

    12.The company should be ready to respond to external influences.

    13.There should be a cultural change in the organization.

    14.There must be effective communication in the organization.

    15.Six Sigma should be linked to business strategy

    16.Six Sigma should be linked to the customers.

    17.Six Sigma should be linked to the suppliers.

    18.Six Sigma should be linked to human resources.

    19.There must be good understanding of tools and techniques of six sigma.

    20.There should also be emphasis on Project management skills acquisition.21.There should be project prioritization, selection, reviews, monitoring and tracking.
