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.

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.
Statistical Sampling
This involves choosing part of a population of interest for inspection. An example is selecting sixty-eight
sites from a list of four hundred.
Flowcharting

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

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.

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.
