Monitoring & Evaluation and
Digital Solutions for your projects

Mainlevel supports organisations in the humanitarian, development, academic and private sectors to increase the impact and efficiency of their interventions.

Vision and services

Our vision is to contribute to a world in which evidence-based decision-making becomes the standard for the implementation of any intervention.

We aim at making a difference by enabling organisations to increase the impact of their interventions and reduce the complexity of programme implementation with our expertise in monitoring, evaluation and digitalisation.

Mainlevel provides an innovative approach to digitalisation and to monitoring & evaluation to a wide range of organisations in the development, academic, humanitarian and private sectors. We conduct evaluations, establish learning-oriented monitoring & evaluation systems and develop targeted digital solutions that help our clients to:

  • manage complex programmes based on solid evidence;
  • improve collaboration between stakeholders;
  • efficiently collect and learn from robust data;
  • manage knowledge and turn it into action.

Our team of skilled consultants supports your interventions with short-term assignments, long-term technical assistance and IT development.

Monitoring & evaluation

We develop coherent mechanisms for monitoring & evaluation, ensuring improved reporting capabilities and evidence-based decision-making. Wherever it is suitable or required, we enhance the usability and effectiveness of monitoring & evaluation systems through digital solutions. Our M&E services are based on solid Theory of Change based models.

Services for monitoring

Mainlevel provides consultancy services for monitoring of projects, programmes, intervention strategies and organisational performance.  We are experts in developing monitoring systems that include the following elements:

  • Coaching and consultancy on theories of change
  • Formulation and classification of indicators
  • Identification of data sources
  • Development of adequate data collection methods
  • Analysis and processing of data
  • Development of dissemination and reporting strategies

"In our multi-stakeholder education initiative we are now able to collaborate and report efficiently based on a commonly agreed monitoring system developed by Mainlevel"

Services for evaluation

Mainlevel independently evaluates projects, programmes, intervention strategies and organisational performance in a way to support the derivation of lessons learnt and formulation of pragmatic recommendations. We are able to base our evaluations on:

  • Complex theory of change models specifying the logic of an intervention
  • Existing methodologies used by OECD-DAC, EU, GIZ, World Bank, SDC, etc.
  • Experimental and quasi- experimental designs
  • Psychological and sociological approaches (e.g. behavioural theories)

Digitalisation & IT solutions

We provide digital strategies and IT solutions that support more efficient project management, monitoring and collaboration. Our tools and strategies aim at bridging the gap between project stakeholders and between implementation and management. Our digital services are based on user-centric, agile approaches.

Mainlevel develops and implements digital strategies for any kind of intervention on national, regional and organisational level. Our solutions refer to a wide range from individual digital components to a holistic digital platform including the following services:

  • Analysis of existing processes, structures and tools in terms of efficiency
  • Assessment and definition of “digital needs” and requirements
  • Recommendations on technological opportunities
  • Design of a holistic digital strategy aligned to the specific context
  • Development of sub-strategies for communication, social media and capacity development
  • Coaching and training on the use of digital solutions

"The digital framework designed and currently implemented by Mainlevel leads to increased civic participation through better access to information and improved dialogue between government and citizens."

Facilitating programme management

Terms of Use

To inform you about our policies and activities relating to the collection, use and disclosure of personal data on the Internet, Mainlevel Consulting AG (or “Mainlevel”) provides this policy in electronic form. This policy applies to all websites owned or run by Mainlevel, their subsidiaries, branches and/or companies directly or indirectly controlled by Mainlevel. It does not apply to websites that have their own data privacy policy. The website you are currently using is referred to below as the “website”.

In this policy, the term “personal data” refers to data that relates to an individual and identifies this person either directly or indirectly (in conjunction with other information that may be likely to come into the possession of Mainlevel), such as your name, email address or telephone number.

Collection of personal data
In general, you can access Mainlevel’s website without providing any personal information. Your browser transmits information to our server which are technically necessary for display our website and to ensure stability and security. These are IP address, date and time of the request, time zone difference to GMT, content of requests, access status / http status code, amount of data transferred, webpage that the request comes from, browser, operating system and its interface and language and version of the browser software.

To access some areas of our website, for example to apply for a position or get in touch with us, we may need to obtain personal data from you. The entering of personal data in such cases is voluntary, and you are explicitly requested to provide such personal data and informed about the intended use of such personal data. If you do not provide us with the required personal data, you may won’t be able to use some functions offered by our website. The typical reasons for us collecting personal data are listed below, along with a brief description of how your personal data is treated in each case.

  • Communication with you. We will respond to any comments and requests that you submit to us through our website, such as online enquiries, comments, or registration to attend an event. This may involve calling you on the telephone or sending an email to you.
  • Creating aggregated statistics regarding the use of our website.
  • Your personal data will be stored accordingly on our systems.

Particularly sensitive personal data
As a rule, Mainlevel does not obtain any “particularly sensitive personal data” via its website. “Particularly sensitive personal data” includes personal data concerning race, political opinion, religious or philosophical beliefs, trade union membership, health or sex life. By voluntarily providing us with particularly sensitive personal data (such as by submitting your CV or applying for a job online), you expressly consent to the use of your personal data as described in this policy.

Disclosure of your personal data
Mainlevel is a global organisation. Our internal processes and infrastructures are therefore international in their nature and scope.

Accordingly, you should be aware that we may share your personal data with third parties, for the purpose of processing it on our behalf. We require that third parties treat the personal data they receive in accordance with Mainlevel’s Data Privacy and Security Policies.

Your personal data may therefore also be subject to cross-border disclosure. Cross-border disclosure of your personal data will be conducted only (i) to countries with equivalent data protection standards, or (ii) on the basis of officially recognized data protection agreements, or (iii) on the basis of officially recogniz ed standard data protection clauses.

Your rights
Below you find more detailed information on your rights regarding the processing of your personal data under the General Data Protection Right (GDPR):

I. Right of access
As a data subject, you have a right to obtain access and information under the conditions provided in Article 15 of the GDPR. This means that you have the right to obtain confirmation from us as to whether we are processing your personal data. If so, you also have the right to obtain access to the personal data and the information listed in Article 15 paragraph 1 of the GDPR. This includes information regarding the purposes of the processing, the categories of personal data that are being processed and the recipients or categories of recipients to whom the personal data have been or will be disclosed (points (a), (b) and (c) of Article 15 paragraph 1 of the GDPR). You can find the full extent of your right to access and information in Article 15 of the GDPR, which can be accessed using the following link.

II. Right to rectification
As a data subject, you have the right to rectification under the conditions provided in Article 16 of the GDPR. This means that you have the right to receive from us without undue delay the rectification of inaccuracies in your personal data and completion of incomplete personal data. You can find the full extent of your right to rectification in Article 16 of the GDPR, which can be accessed using the following link.

III.  Right to erasure (“right to be forgotten”)
As a data subject, you have a right to erasure (“right to be forgotten”) under the conditions provided in Article 17 of the GDPR. This means that you have the right to obtain from us the erasure of your personal data and we are obliged to erase your personal data without undue delay when one of the reasons listed in Article 17 paragraph 1 of the GDPR applies. This can be the case, for example, if personal data are no longer necessary in relation to the purposes for which they were collected or otherwise processed (point (a) of Article 17 paragraph 1 of the GDPR). If we have made the personal data public and are obliged to erase it, we are also obliged, taking account of available technology and the cost of implementation, to take reasonable steps, including technical measures, to inform controllers which are processing the personal data that you have requested the erasure by such controllers of any links to, or copy or replication of those personal data (Article 17 paragraph 2 of the GDPR). The right to erasure (“right to be forgotten”) does not apply if the processing is necessary for one of the reasons listed in Article 17 paragraph 3 of the GDPR. This can be the case, for example, if the processing is necessary for compliance with a legal obligation or for the establishment, exercise or defence of legal claims (points (a) and (4) of Article 17 paragraph 3 of the GDPR). You can find the full extent of your right to erasure (“right to be forgotten”) in Article 17 of the GDPR, which can be accessed using the following link.

IV. Right to restriction of processing
As a data subject, you have a right to restriction of processing under the conditions provided in Article 18 of the GDPR. This means that you have the right to obtain from us the restriction of processing if one of the conditions provided in Article 18 paragraph 1 of the GDPR applies. This can be the case, for example, if you contest the accuracy of the personal data. In such a case, the restriction of processing lasts for a period that enables us to verify the accuracy of the personal data (point (a) of Article 18 paragraph 1 of the GDPR). Restriction means that stored personal data are marked with the goal of restricting their future processing (Article 4 paragraph 3 of the GDPR). You can find the full extent of your right to restriction of processing in Article 18 of the GDPR, which can be accessed using the following link.

V.Right to data portability
As a data subject, you have a right to data portability under the conditions provided in Article 20 of the GDPR. This means that you generally have the right to receive your personal data with which you have provided us in a structured, commonly used and machine-readable format and to transmit those data to another controller without hindrance from us if the processing is based on consent pursuant to point (a) of Article 6 paragraph 1 or point (a) of Article 9 paragraph 2 of the GDPR or on a contract pursuant to point (b) of Article 6 paragraph 1 of the GDPR and the processing is carried out by automated means (Article 20 paragraph 1 of the GDPR). You can find information as to whether an instance of processing is based on consent pursuant to point (a) of Article 6 paragraph 1 or point (a) of Article 9 paragraph 2 of the GDPR or on a contract pursuant to point (b) of Article 6 paragraph 1 of the GDPR in the information regarding the legal basis of processing in Section C of this Data Protection Information. In exercising your right to data portability, you also generally have the right to have your personal data transmitted directly from us to another controller if technically feasible (Article 20 paragraph 2 of the GDPR).
You can find the full extent of your right to data portability in Article 20 of the GDPR, which can be accessed using the following link.

VI. Right to object

At the latest in our first communication with you, we expressly inform you of your right, as a data subject, to object. As a data subject, you have the right to object, on grounds relating to your particular situation, at any time to processing of your personal data which is based on point (e) or (f) of Article 6 paragraph 1, including profiling based on those provisions. In the event of an objection relating to your particular situation, we will no longer process your personal data unless we can demonstrate compelling legitimate grounds for the processing which override your interests, rights and freedoms or for the establishment, exercise or defence of legal claims. You can find the full extent of your right to objection in Article 21 of the GDPR, which can be accessed using the following link.

VII. Right to withdraw consent
Where an instance of processing is based on consent pursuant to point (a) of Article 6 paragraph 1 or point (a) of Article 9 paragraph 2 of the General Data Protection Regulation, as a data subject, you have the right, pursuant to Article 7 paragraph 3 of the General Data Protection Regulation, to withdraw your consent at any time. The withdrawal of your consent does not affect the legitimacy of the processing that occurred based on your consent until the withdrawal. We inform you of this before you grant your consent.

VIII. Right to lodge a complaint with a supervisory authority
As a data subject, you have a right to lodge a complaint with a supervisory authority under the conditions provided in point (f) of Article 57 paragraph 1 of the General Data Protection Regulation.
